Collaborative newsletter for ScienceMadness??

symboom - 18-10-2018 at 10:44

By the month like for instance making sodium metal by alcohol catalysis or nitric acid by transition metal salts was finished on 24 Oct link to the wiki it might make building the wiki easier it would have the current montlth and a point in history on that month or something like that.
I think this will raise awareness and interest in more experiments to further the study in that direction.

Seems a bit forced. Some months are very busy while others may have very little to report on.

Edit: An annual report may be more feasible, and it would be a good stepping stone towards the journal.

Oct 2018 or
2018

Sodium metal has been made using everyday chemicals.

Similar to in a thread in sciencemadness fourm in which potassium is made in an armateur setting an obscure pathway to sodium metal by alcohol catalysis had been achieved using common chemicals. the chemicals sodium hydroxide tea tree oil and magnesium. Turning something ordinary to extraordinary is common with armature chemistry.
A turning point and Change in what is possible with so few chemicals.

What else has happened in 2018

Just a thought it's short have more to add this is what I have so far.

Publishing every month might be a bit ambitious, but a semi-annual newsletter or perhaps an annual State of Mad Science report is an excellent idea. Hard deadlines will encourage people to get things accomplished and submit their work.

Heptylene - 18-10-2018 at 13:06

I really like the idea of an annual report. It gives a sense of importance and "officialness" (I don't have a word for that). But a group of people would have to decide what to include: what is relevant and what is not. That might generate some conflict and competition between the members, maybe in the same way that the race for publication in presitigious journals does.

Or maybe a poll could select what makes it into the annual report? Maybe a poll with many criteria, for example: quality of the post, interest generated, impact on the amateur community, how successful it was, etc. as perceived by the members.

Maybe a "hot topics" section would be appropriate, where top-voted and recent threads could be rewarded. Like a thread-of-the-month but with some flexibility in the duration.

Just a few thoughts

Oh, that's called "flattery."

You'd think that a single editor would be able to handle it.

I really think this is the wrong approach. Chemistry isn't a popularity contest; any decison as to what makes it into the final newsletter should be made on rational grounds by people who are competent chemists.


Texium - 18-10-2018 at 15:24

I'd be happy to write up the annual report! If it was to get published in January of each year I should be able to do it no problem, as I have a lot of free time in winter.

  • Significant experiments presented by members
  • Significant new procedures -- since Nurdrage's progress on the sodium has occupied much of out thoughts and a bit of discussion. (Although I am not aware of anyone who is actually following his procedure yet.)
  • Significant postings and procedures in prepub
  • Changes in availability of chemicals / equipment.
  • Changes in legislation that affect members.

    Some things related to this community:
  • progress on the spam issue
  • we had SM member of the year a while back (thanks to aga). Maybe some accolades to individuals.
  • Highlights from some of the favourite threads: pretty pictures, tour my lab, that kind of thing
  • Personal developments: for example Tdep's great new (top secret) job doing chemistry for the military. Metacelsus heading off to the UK to pursue some great opportunities in education. Blagfost26 (not his real name) saying, "to hell with it: if you can't beat the system you may as well go all-in" and opening a corner store selling sodium perchlorate to card-carrying terrorists.

    Very true thank you for resurecting the thread if any thing is new it should be included.

    J_sum_1 has many good ideas along with others thoughts and concerns Voting seems to be the quickest way to Finish a lot of the project.
    if there is any disagreement we should have a poll to maintain constructive discourse.

    NEW PROCEDURES

    Make Sodium Metal with Menthol
    It is a great project and achievement for the experienced amateur chemist
    A more efficient way to obtain sodium metal heat sodium hydroxide with magnesium in mineral oil above 200 °C, in the presence of a tertiary or sterically bulk secondary alcohols, like t-butanol and menthol. The yield of this route if done right can be as high as 90-95%, though the process takes hours to completion.

    Make Nitric Acid by Thermal Decomposition of Copper Nitrate
    Copper sulfate is reacted with calcium nitrate the resulting calcium sulfate is filtered from the solution as copper nitrate remains.
    This reaction is a cheap source of nitrogen dioxide, which can be bubbled through water to generate nitric acid.
    The gas can also be bubbled into hydrogen peroxide producing a higher yield

    Preparation of elemental phosphorus
    (The lesser known reactions)

    Cleaned, boiled and dried chicken bones (bone meal can also be used with if used as organic firtalizer) are burned with a bunsen burner on a fireproof surface and directly heated with the flame until they have turned into white ash.
    2g of this bone ash are mixed with 0.5g magnesium powder
    or activated carbon powder and 0.5g Diatomaceous earth. The mix is heated and vapors are lead underwater for the vapors to cool and condense to white phosphorous.
    ----
    low-temperature production of phosphorus,

    the most interesting candidates appear to be phosphates of lead, bismuth, and antimony. silver phosphate can be
    reduced and yields finely divided metallic silver and phosphoric acid, which is catalytically reduced in the presence of the silver to give free phosphorus.


    lead phosphate is reduced under hydrogen or methane with hydrogen resulting in the highest yields and methane at 50%
    The reaction consists of three stages: 1. The Pb3(PO4)2 is heated up to 300C to drive off any existing water.
    2. Once the temp hits 300C the hydrogen is turned on and the tempurature slowly raised to 500C. The hydrogen reduces the Pb3(PO4)2 by ripping off the oxygen molecules and forming Pb3P2, aka lead phosphide.
    3. Upon the cessation of evolution of water, the furnace is again slowly raised up to somewhere between 650-800C. According to the patent, small amounts of PH3 are liberated at around 600C. This makes sense, the Pb3P2 probably starts to break down somewhere around 600C and thus liberates PH3, which subsequently start to be reduced to H2 and elemental P at around 650C, so basically at the beginning of the reduction temp the phosphine being liberated is not hot enough to break down.

    phosphates can be reduced by hydrogen at temperatures between 300° and 750°C. Lead phosphates are particularly easy to reduce by hydrogen. For example, pyromorphite, 3Pb3(PO4)2*PbCl2, starts to react at 300°C and is completely reduced at 850°C.

    Other possible reducing agents
    CaC2 would make a good reducing agent in such a reduction as phosphate reduction. I suspect that sodium polysulfide would work well in a phosphate reduction. 4Na3PO4 + 2Na2S2 ----> 8Na2O + 4SO2 + P4

    Using sodium acetate as a carbon source
    fusing Hexasodium metaphosphate with Sodium acetate the mixture liquefies quickly and a strong smell of garlic was released. Sodium acetate acting as a carbon source and a flux because once the melt was fluid there was a large release of Phosphorus.

    Phosphorous from phosphine
    phosphine with dimethylchloramine, which reacts to form elemental phosphorus and dimethylammonium chloride (as
    reported here: http://pubs.acs.org/doi/abs/10.1021/ic50067a009).

    "Journal of Amateur Chemistry"?

    clearly_not_atara - 21-10-2020 at 10:04

    We had had another similar thread proposing a free journal for home chemistry, with a poll for the name -- I liked Acta Chemica Libera -- but this effort is much more specific, with no submissions, just a report on what happens on the forum.

    So I think the better name is just Mad Science Reports or something else containing "ScienceMadness" or "Mad Science". It also sounds more tractable because honestly neither I nor anyone else had the time to run a journal apparently (and I have less time these days).

    Also I would suggest putting the "journal" out every two months rather than every month, truly interesting results don't come around that often and it would save half of the work.

    Organic Chemistry

    Many amateurs have attempted to make acetic anhydride at home due to its tremendous usefulness in organic chemistry. Only a few have succeeded, though a write-up of the preparation of acetic anhydride from sulfur, bromine, and anhydrous sodium acetate was reported by Magpie.

    Another more accessible method involves the reaction of acetyl chloride and anhydrous sodium acetate.[1]


    A preparation that is as of yet not well-researched involves the dry vacuum distillation of anhydrous zinc acetate, which gives off acetic anhydride and converts to basic zinc acetate. If achievable, this would mean a route to acetic anhydride that only requires glacial acetic acid and cheap zinc metal.

    bromine is the limiting reagent. The sulfur, except that released as SO2, is recycled in situ.

    Vacuum Distillation
    Set up for vacuum distillation of the Ac2O using the 3-neck 500mL RBF. Place an insulating blanket over the RBF. With a vacuum of 23”Hg (absolute pressure = 178 mmHg) the Ac2O comes over at about 72°C. Yield of the crude Ac2O will be ~30 mL.

    E. Simple Distillation
    Set up for simple distillation of the crude Ac2O at atmospheric pressure. Use a 50 mL RBF as pot. Collect 2 cuts. The first cut (~15 mL) will come over at about 128-135°C. The 2nd cut (~10 mL) will come over at 135-143°C. Literature value for the bp of Ac2O is 140.0 °C. Yield, based on the 10mL of cut 2 and the amount of Br2 charged, is ~27%.

    Sulfur trioxide


    The preparation of this compound is extremely dangerous and should only be attempted by chemists with experience working with hazardous volatile reagents.

    SO3 can be made in low yield through the pyrolysis of sodium persulfate, first forming ozone and then SOSO3. A catalytic amount of 100% sulfuric acid is required.

    Nearly the same reaction takes place when sodium bisulfate is very strongly heated, first evolving water, forming sodium pyrosulfate, which then decomposes above 460 °C to sodium sulfate, releasing SO3.

    There are reports that heating sodium pyrosulfate with concentrated sulfuric acid to 150°C results in SO3 and bisulfate.

    Heating iron(II) sulfate at 700 °C with carbon yields iron(III) oxide, sulfur dioxide and sulfur trioxide. The same reaction also works with iron(III) sulfate, at a much lower temperature, 480 °C, and produces mostly sulfur trioxide.

    Pyrolysis of copper(II) sulfate above 560 °C yields sulfur trioxide and copper oxide. If the temperature gets lower, copper sulfate will reform. Aluminium sulfate also works, though the decomposition temperature is slightly higher.

    Adding phosphorus pentoxide to extremely concentrated sulfuric acid will release sulfur trioxide, which can be extracted via distillation. Metaphosphoric acid can also be used instead of the pentoxide.

    Roasting calcium sulfate with silicon dioxide (very fine sand can be used) at 1000 °C for 1 hour yields calcium silicate and sulfur trioxide. Adding small amounts of chromium(III) oxide or tungsten(IV) oxide improves the process.[3]

    In industry sulfur trioxide is produced via the contact process. Purified sulfur dioxide is mixed with dry air and injected through a bed of V2O5 catalyst heated to temperatures between 400-600 °C (the optimum temperature is 450 °C), at 1-2 atm. The resulting hot sulfur trioxide is recirculated and passed through more layers of catalyst to increase the yield. The gaseous SO3 is cooled by passing it through a heat exchanger and can be collected if required. The condensed trioxide is dissolved in concentrated H2SO4 in the absorption tower to form oleum.

    Sulfur trioxide can also be obtained by oxidizing sulfur dioxide in the presence of several metal oxides, such as copper(II) oxide at high temperatures[4] or chromium(III) oxide (at temperatures between 180-400 °C).[5]


    Sulfuric acid


    How to make sulfuric acid by electrolysis of copper sulfate using an inert anode. Copper sulfate is very easy to obtain in large quantities at gardening and hardware stores and provides a convenient route to sulfuric acid if the appropriate anode can be obtained.

    Warning: This should be done in a well-ventilated area as hydrogen gas build up is explosive. Copper sulfate is toxic and sulfuric acid is corrosive, wear gloves when handling them.

    The procedure is extremely simple, just get a copper sulfate solution, insert two electrodes and run a current through them. The anode, the positive electrode, must be an inert material that can withstand extremely oxidizing conditions. Very few materials meet this condition, platinum, lead dioxide, and carbon among them. Other metals, even stainless steel, are quickly destroyed under these conditions and cannot be used. The cathode, the negative electrode, is exposed to reducing conditions so the metal requirements are must less stringent. Copper is the best choice here since it has high electrical conductivity.

    When applying power, the current should be adjusted so that corrosion at the positive terminal and bubbling at the negative terminal are both minimized. The bubbling at the negative terminal is hydrogen production and that's wasted energy that should have gone into reducing the copper sulfate.

    After the solution has gone clear, filter off the particles and the clear filtrate is dilute sulfuric acid that can be boiled down to obtain concentrated sulfuric acid. It will have trace amounts of metals but for most purposes this is not an issue.

    Keep in mind that it will take a long time for the solution to go clear. if after filtering it's still blue, you'll need to keep electrolyzing it. You'll need over 60 amp hours of current per mole of copper sulfate, and usually more since the process is not very efficient
    _____

    Make Sulfuric acid (metabisulfite/oxidizer method)


    sulfuric acid from sodium metabisulfite, hydrochloric acid and an oxidant such as hydrogen peroxide or nitric acid.

    Warning: The procedures in this video produce large quantities of toxic gases and deal with highly corrosive acids. All work must be performed in a fume hood with proper safety equipment. And all apparatus must be glass to withstand the acids.

    Sodium metabisulfite upon reaction with acid will generate sulfur dioxide. This provides a convenient source of sulfur dioxide that is easier to handle than burning sulfur, but it is acceptable if you want to go that route. You'll just need to build a sophisticated gas capture and scrubbing system so the sulfur vapors and soot don't clog your tubes, poison your air and possibly burn down your workspace.

    Sulfur dioxide is converted into sulfuric acid by reacting it with an oxidizer in water. In this case either hydrogen peroxide or nitric acid.

    Industrially, sulfur dioxide is reacted with oxygen over a catalyst to make sulfur trioxide. This is cheaper but extremely difficult to do safely for the home chemist so the metabisulfite/oxidizer method is used instead.

    You may use potassium metabisulfite instead of sodium metabisulfite. Both are used by home brewers to sterilize winemaking and beermaking mixtures. It's also used for homemade dyeing processes. Therefore it is very easy to obtain the metabisulfites without the need for expensive shipping fees or licenses.

    The oxidizers must be present for this reaction to work. You cannot simply use water or you'll just make sulfurous acid which decomposes on heating and is useless for the reactions that sulfuric acid is intended for.

    In future videos, we may show other methods of sulfuric acid production including sulfur trioxide based methods so please subscribe!




    Make Sulfuric Acid by the Copper Chloride Process


    Take a solution of copper (II) chloride and bubble sulfur dioxide into it until most of the copper (II) chloride is converted into copper (I) chloride. This reaction also converts the sulfur dioxide into sulfuric acid and produces hydrochloric acid. Now the copper chloride can be regenerated by bubbling air into the mixture until the copper chloride dissolves again. This cycle can be repeated. When you want to isolate the sulfuric acid you forgo air infusion for that step and filter off the preciptated copper chloride. Then you distill off the hydrochloric acid and water from the filtrate. The sulfuric acid left behind will precpitate out most of the remainig copper salts and when filtered will give you relatively pure sulfuric acid with some water and minor copper contamination. The copper chloride can be recombined with all the hydrochloric acid from before and the cycle repeated.

    ________

    Sulfuric acid water and sulfur (electrobromine process)


    make sulfuric acid from sulfur and water using electrolytically generated bromine as the catalyst.

    Warning: Bromine and sulfur bromides are volatile and toxic. This might be done outside or in a fume hood.


    We start with 16g of sulfur in a 250 ml beaker. We install 5 lantern battery carbon electrodes for the anode and a copper wire for the cathode. To this setup we add 200mL of 5M hydrobromic acid. The copper cathode is readjusted to be as physically close to the top of the electrolyte as possible while still being immersed in it. A current is then applied of less than 2 amps. The electrolysis is performed for 40 hours with occasional stirring and addition of water to make up for evaporative loses.

    Whats happening is the electrolysis converts hydrobromic acid to bromine and hydrogen. The hydrogen bubbles away and the bromine reacts with sulfur to produce disulfur dibromide. This in turn reacts with more bromine and water to produce sulfuric acid and hydrobromic acid.

    At the end of the run, the solution is filtered and then refluxed for 30 minutes to drive the conversion to completion. The solution is then distilled to first recover water, then hydrobromic acid and finally sulfuric acid.

    Progress so far
    This is the information I want to add
    At the moment I'm compiling it onto
    My laptop with abiword my free trial of word ended in my laptop. It saved with a .doc Microsoft word compatible format.

    I plan to do a poll after i complete the final draft

    Which will say
    Is the mad science report newsletter ready to be added to prepublication

    Final draft posted on the poll

    >Yes
    >No I would add
    >No I would remove

    For it to be ready

    Hello everybody,

    Creating a journal/magazine may be a very challenging task.
    It will require a lot of work but I feel it is worth it.

    If I can be helpful in anyway (e.g. graphical design, reaswrch, etc.), I will help.

    Thank you for your effort.

    P.S. It can be named: Journal of Mad Science, or something. I am not the best in creative titles.

    @BrainAmoeba
    Hey graphical design sounds great and would really make this work
    For research this is a completion of sciencemadness and many discussions are based on articles on other web sites. If there is something you feel like would be a great addition go for it and post pieces of it here.

    We want typesetting!
    I'll try to mock something up this weekend if nobody gets to it
    before me.

    A note of encouragement of collaberation
    The only thing I worry about is this project dying in the process as one person waits for the other person and doesn't want to put out the samething most of the time you will be the only one and we could always vote if needed. Whatever gets this to it's goal before January. Unfortunately that happens a lot with collaboration projects. It happened with the collaboration book of chemistry, and many others it is hard to do. Don't be discouraged if any one wants to try it have a hand at it.

    Glassware is not illegal in texas anymore. That law was repealed in 2019

    hello guys, first post here, i've been browsing the forum several years ago, the idea of ​​the periodic publication journal brough my attention and im planning on being more active user.



    This is some great news and what I intended it to help with engagement so amature chemistry can grow more with the newsletter then the journal can be build on this momentem
    I don't want to stifle innovation.
