Where can one obtain this? Any tips chemheads can give me to obtaining (or making) this. thanks.

There are many ways to get anhydrous HCl gas just do some research.You could heat muriatic acid or you could go with H2SO4 + NaCl

The cheapest easiest way to dry HCl gas is by dumping salt into concentrated >98% sulphuric acid. The reagents are dirt cheap, and the gas is automatically dry cause there is no H2O in the reaction to begin with.

Muriatic acid when heated gives off HCl and H2O so you need to bubble it through H2SO4 to dry it.

If you can't get 98 percent H2SO4 you aren't looking hard enough.

I dump sulphuric acid and 35% hydrogen peroxide (peroxysulphuric acid) down my drain to burn out hairballs.

thanks ghetto. do you know the right temp to get the muriatic acid to fume just right? i tried doing some research on it, i must not of tried hard enough but none of my chem books mention it. if you could give me some helpful hints on this process (since im a beginning chemhead obviously) i could trade you info on psilocybe production (if interested) as that is my specialty. thanks.

edit: 98% sulphuric acid is beyond my reach and im paranoid about mail-order, tryptamine; however i do appreciate the muriatic acid cleaning method you mentioned.

email me and I'll help you

Simply heating HCl near boiling will produce lots of vapour of HCl gas and water. Pass through several drying tubes filled with dried MgSO4.

You could set up a flask w/ an 3-way adapter attached... on the top place an equalizing addition funnel... and place HCl in there. In the flask place some H2SO4. On the remaining attachment place a hose convertion. When the HCl is dropped into the H2SO4 it will create anhydrous HCl(g)... I have gotten the highest yeilds this way.

Nuglobe you are explaining to a ghetto chemist how to make gas with an apparatus he will never own, with reagents he can't get.

Muriatic acid will also work if you put a shitload of salt into it, you don't have to heat it and your gas will stay dryer. Don't tell me you can't get 98% sulphuric acid, hardware store(drain opener), plumbing supply store, Fuck I'll send you some.

thanks everyone for the info, i didn't realise there was so many methods. Tryptamine, they really don't sell 98% sulphuric acid in hardware stores do they? i woudn't imagine using a product that contains other shit besides sulphuric acid, unless you know an extraction method you would be kind enough to tell? thanks everyone, keep em comin.

Yup they do sell 98% sulphuric in hardware stores, it is brownish syrupy shit that will burn you like you've never thought possible. Sure it has impurities in it but it is fine for making HCl gas as these impurities don't go anywhere. If you need it purer for any other reason you need to vacuum distil (with an aspirator please) cause it decomposes to SO3 before it boils at atmospheric.

okay tryp, how do you ventilate the ether+ meth free-base solution w/ the hcl gas bubbling through too? what can i do to get rid of this dangerous gas?

'If you need it purer for any other reason you need to vacuum distil (with an aspirator please) cause it decomposes to SO3 before it boils at atmospheric.'


Remember... ghetto... ghetto

Nuglobe: Yes I know, but they will never need H2SO4 any purer so they won't need to vacuum distill.

As far as how to gas, just bubble through with your tube in the liquid. you can do this inside if you control the amount of gas produced. A little extra escaping into the room won't hurt anything. Alot escaping will rust anything metal and burn your lungs so if you go overboard with the gas generation or are worried do the gassing outside.

Alternatively you can rig up a gassing bottle that has another tube going off the (sealed) top going into a bottle of NaOH solution. This now can be done inside.

Instead of running the second tube through that... if you run it through a cup of DH2O the HCl(g) w/ bond with the water forming HCl. You then go reuse any extra gas that was produced. Thats how a guy in my dream does it.
