Hey, Ace is the place to go for me! Rooto baume 98% H2S04. Several specialty shops sell food grade Na0H and K0H.
I'm waiting for the day they take away everything, for shortly there after, secret and devilishly easy recipes will spring forth from a Pandora's box.

business. Mixtures of narcotics superior to heroin. Synthetic caines, full of power, but low on the NE and easy on the heart.

I wonder if the nitrate is in there to control the temperature, since it has a really endothermic heat of dissolution?
Otherwise, the stuff with the aluminum chips is like a "drano bomb" in a can... just add water!

The nitrate is reduced to ammonia, I don't know why though, maybe to raise the heat?
I never asked for this.

Needing some toluene I visited Ace, my usual source for OTC chemicals. They had it but only in a 1 gallon container. I was able to find it at other
hardware and paint stores but also only in 1 gallon containers. I finally found the 1 qt size at a recreational equipment store. Apparently it is
the solvent of choice for repairing inflatable rafts.
I was happy to note that MEK is still available at Ace and other places. In fact the Klean-Strip website says that the "MEK substitute" is being
discontinued. Sometimes we win one.

nitrate stump remover with the metabisulfite variety, and naphthalene moth balls with the p-dichlorobenzene kind.
I think the bigger stores are afraid of their public image. A small chain is much more concerned about money than looking "environmentally
responsible" in the public eye. Also, the bigger stores have a lot more to lose if someone is injured by one of their products. I'm sure they have a
legal department which does nothing all day but sit around and think of what could go wrong and how to prevent it. |
Yeah man, that shit sucks. Does banning xylene and friends (solvents, hydroxides) have a significant impact on the environment? I'd imagine much of
the problem is caused by industrial manufacturing or something, rather than individual dumbfucks pouring solvent all over the place.

It must vary by state. My buddy in California has told me his local Home Depot carries NO workable solvents or hydroxides barring acetone (offered
only in 16 oz cans). Thankfully it's not quite that bad here, but I'm not optimistic for the future.

reduction to ammonia because the average person would shit themselves knowing that NaOH on contact with aluminium forms nicely explosive hydrogen gas,
probably even the NH3 forms NH4OH which .. ofcourse also helps to remove plugs of whatever sort
there should be a SM main base in the US and in the EU.. buying home a tonne of all sorts of chemicals running our own business 
i mean.. who havent been gazing at the insanely low prices on alibabba for bulk chemicals??

I have actually considered making a business out of chemicals. Now when there is the bitcoin, it makes it a lot simpler but unfortunately my country
is very much too remote and authoritarian for such purposes. Even if I managed to smuggle out some concentrated hydroxic acid, the shipping costs
would render the business obsolete. On a second thought, I have noted that once you get a registered company, you can order virtually anything without
nobody raising a question, even the bad-badies.

Good thing I recently bought 1 gallon of 96% Rooto sulfuric acid at Ace, also Ammonium Nitrate happens to be the only OTC Nitrate salt available to
me, so I got plenty of that too

In the Netherlands we have a new development. Many hardware stores want to go ECO. In practice this means that many chemicals which are "bad for the
environment" are banned. Solvents like white spirit, ligroin and even acetone are replaced by their eco-variants. So, instead of acetone we can buy
eco-acetone, which is a mix of at most 10% butoxyethanol, water and soap-like stuff and is inflammable and does not need to carry the Xi or Xn hazard
symbol.
http://www.pearlpaint.nl/nl/merken-producten/eco-line/aceton...
They even call this crap acetone, but it does not contain any acetone at all. I almost bought a bottle of this stuff, but when I read the label on the
bottle I decided to leave it.
Not only acetone is replaced, but nearly all solvents, and also sodium hydroxide and somewhat more concentrated hydrochloric acid. For the home
chemist, this is a small disaster. So, very soon, in the Netherlands the only source of pure chemicals will be special online shops.

I have decided to only buy online anyway, It's cheaper, so the only downside is shipping costs. But if you buy only large shipments, you save lots of
money, and the chemicals are more pure.

I just buy my chemicals on amazon for the most part. I have an Ace just a few minutes away, but I end up paying more money for a worse product. I can
get a 2lbs of FCC grade NaOH for $15, 1L 32% HCl for $15 on amazon, but I would pay probably $28 for 2lbs of NaOH drain cleaner at Ace. I get way
better deals and they have way more things.
Since all of the chemicals you can buy through amazon aren't actually sold by amazon I don't have to worry about setting off any red flags for buying
a bunch of reagents. Each third party seller is responsible for tracking their chemical sales - not that I buy any suspicious chemicals or bulk
chemicals. It's just a added benefit of using amazon third party sellers. I also use ebay if amazon doesn't have something for whatever reason.

Do you think that the NSA really doesn't share all that lovely
data with the FBI/DEA/CIA? Amazon and Ebay are 'watched'
but given the volume of transactions it may take years to
actually get investigated.

No but I think they have bigger fish to fry than some 23 year old kid buying small quantities of unwatched reagents. I would fear a local raid from
police working under a tip or something but I don't think the NSA is giving info to the local police on my buying habits.

8lbs of NaOH for 15.99.. think the industry it is used in and wash your hands of losing your hard earned money. Or you can pay 15.99 for 2Lb at your
local hardware store because it is convenient..

I got 5 gallon cans of acetone and toluene from a paint store. Then they had a fire and went out of business. I can still buy methanol from a fuel
seller.

Even the Ace hardware website says it's discontinued  . I just bought a liter from
Ace the other day - I guess I'll be going back to buy a few gallons. It's way more expensive to buy ethyl acetate on amazon.

Are you sure ethyl acetate is in the substitute formulation of MEK? I was just at home depot and I saw 1qt bottles of MEK "substitute" (Klean
Strip). There was a good 24 bottles on the shelf.
If so, what percentage of it contains EtOAc? I believe it was 10.00 per quart. I googled but could not find the answer regarding the constituents in
the formulation.

I have used just plain ethyl acetate from the bottle for extractions, and it works fine. For more sensitive reactions, I distill, and I have not had
any problems.
