Sorry I thought it was just a name give by the calgon company to this material.
It gives little information on whats in it other then its a special watersoluble phosphate compound for use in micromat system(water purifiers).
Its a glass like substance pretty clear and broken into clear chunks roughly the size of a BB.

1-pentyl-3-(1-naphthoyl)indole, JWH-018.
I have made this compound on 3 occasions and after alkylation in DMSO/KOH or DMF/KOH I receive an amber oil which is slightly gummy, as expected.
But there are reports of the pure substance being a yellowish solid, or even white, while Huffman reports it as the amber gum. Which is it? Does
oxidation or some other factor cause it to be an amber gummy oil? I ask because there seems to be no sure answer after a browse on the net.
Over at hyperlab in the cb agonist thread one person received it as a solid, others as oil. The oil is apparently crystallizable from ethanol. I do
not need it in a particular form, but I wonder what causes it to take these different forms.

I have a question that i can't get my head around.
I saw this video : http://www.youtube.com/watch?v=m4fGIiIpY7A
It's in russian so i don't understand , but they seem to react molten sulfur with H2SO4?
Does sulfur really react with sulfuric acid? What are the products?

This is just my speculation. That the sulfuric acid oxidizes the formed SO2 into SO3 which reacts to form oleum. Sulfur is also formed as a product
visible on the testube
3 SO2 + 2 H2SO4 = S + 2 H2S2O7

I see everyone is trying to make phenol, but I see no things that can be done with it. What are some reactions or syntheses that I can do with it?

Well, I understand Russian.
And he is saying that reacting molten sulfur and hot concentrated sulfuric acid produces SO4 (how exactly thats possible- don't have a clue).

Sounds like tryptamine chemistry. It has a long alkyl chain, that usually
doesn't help with crystallization. Have you tried cleaning by chromatography with subsequent crystallization from a solvent? IMHO we should take some
pride in our products and making nice crystals is part of that.

I lack the resources to do a column at this time, but I have been trying crystallization from ethanol and isopropanol. I just cannot get it to
crystallize, it always deposits as little gummy balls on the sides/bottom of the beaker, it is actually very annoying. I'll keep toying with
xtallization from ethanol, and get some column supplies which are long overdue.

Err,today i mix KClO3 with H2SO4,It should produce chloric acid and potassium sulfate:
2 KClO3 + H2SO4 → 2 HClO3 + K2SO4
But mine have a gas released in the reaction,a pale yellowish-green gas,I tried to burn it,as I thought it was,it exploded.It is chlorine oxides.![:o](./images/smilies/shocked.gif)
So,which chlorine oxides produced here,and why does it produced?It should not been produced according to chemical equation.Maybe it was produced
because I am not using pure sulphuric acid?

Yikes ClO<sub>2</sub>!
Heres my short question:
Does mercury react with HCl <b>at all</b>? Like does it even in the slightest amount react with conc. HCl? Because I need to clean some
mercury from some metal oxides/dissolved metals and I was thinking HCl would be a great way but I do not want to have any remaining mercury salts, so
I wont to make sure nothing will happen.

Nope! reactivity series. Needs an oxidizing agent like HNO3.
BUT things like CuCl2 or FeCl3 might be able to oxidize Hg, sort of like etching copper off PCBs.

Thank you for the response!
Ok so if iron is my impurity and I produce FeCl3 then... am I no longer safe?

Fe + HCl --> FeCl2
FeCl2 and oxygen at acidic conditions ---> FeCl3, it could dissolve some mercury
Fe2O3 + HCl --> FeCl3 again, it could
You can use some reducing agents or something, maybe ascorbic acid with HCl

Ok thanks. I don't have ascorbic acid, any others you know will work? What about glucose?

Hello all,
does anyone out there have a good link to a PDF download of, 'Gmelins' it is one of the core I haven't found yet. Any nudge in the right direction
would be appreciated.

It is known that benzophenone condenses poorly or not at all in aldol-type condensations, due to it being insufficiently nucleophilic. Question: how
might thienophenone (2,2'-dithienyl ketone) perform in such mixed condensations, for example, with acetone under basic conditions?

Try with some metal salts that only coordinate with amines, but not with amides. Usually the solutions change colour somewhat after coordination.
Candidates are solutions of CuSO4, CuCl2, CoCl2, NiSO4, etc.
Do you need this for TLC visualization, for photometric determination or what else? Without further information it is no possible to give much of an
advice.

One time I heated a small pile of ammonium nitrate, potassium dichromate and either aluminum or magnesium powder, I don't recall which. With a direct
flame from a propane torch the stuff melted, burned a little and reduced down to some hard nodules about the size of a pea. If you were careful you
could heat these hard nodules to a dull red and nothing would happen. But just a little more heat and they would ignite and take off into the air,
crackling like some kind of electric discharge whizzing about. I remember one piece seemed to chase me like a bee as I dodged it zinging about. I
can't think what it could have been except some kind of thermite-like substance that could resist ignition at such high temperatures.
It kind of reminded me of well melted KNO3 and sugar, how small pieces will take off and whiz about, only these burned much hotter and made a sound
like crackling high voltage ball lightning if such a thing existed.
If you have ever melted or lit ammonium nitrate and aluminum powder, it kind of burns for a little bit and then flames out, flashing on and off with a
direct propane torch heating method. That's sort of how the stuff did with the dichromate added, like a watery weakly flammable goo as it reduced to a
hard rock-like residue.

I have found Platinum powder in an art shop. Its not much but I wanted to get some thoughts on if its ok to use for some reactions or not. Its only .4
grams for about $4 or something like that and I was thinking about using it to plate some electrodes for use in a kolbe electrolysis or something.
What do ya'll think. Would it be of any use?

Most probable explanation is intermediary formation of ammonium dichromate, which then decomposed.
