What is an easy way to create HCl gas?

Here

Okay. First, here is what you need:

1. Beer bottle (transparant).
2. Plastic baby syringe (15 ml capacity) found at the pharmacy section at any
grocery store.
3. Four or so feet of ice-maker transparant-white polyethylene tubing found at
the hardware store. (I don't remember the exact diameter size. All I know is
that it IS the smallest size available.)
4. One table-leg stopper (rubber, beige or black). Another item of which I don't
know the size. Just take your beer bottle into the hardware store and see
which size fits snuggly on its top.
5. One aluminum tube that is the exact diameter size as the polyethylene tubing.
Found at the hardware store but don't know what they are used for. They are sometimes made of brass.
6. One bottle of sulfuric acid drain cleaner.
7. One bottle of concentrated hardware store muriatic acid (32%?)


Assembling the HCl generator is easy.

1. Use the aluminum tubing to burrow two holes to the top of the table-leg
stopper. Use a twisting motion while appling pressure for about a minute
and eventually the tube will pop through.
2. Place the table-top stopper over the top of the beer bottle. It'll fit snugly.
3. Insert the polyethylene tubing into the middle-most hole and push through
until the tubing hits the bottom of the beer bottle. With scissors or a knife
cut off the polyethylene tubing about two inches from the top of the beer
bottle.
4. Take the entire table-top stopper inserted with the polyethylene tubing off
of the beer bottle. Pour into the beer bottle a volume of sulfuric acid about
an inch high off of the bottom of the beer bottle.
5. Replace the table-top stopper/polyethylene tubing on top of the beer bottle.
Insert the remaining tubing into the last hole of the stopper until about
two inches into the bottle. Cut tubing down to desired length.
6. Pour about twenty milliliters of concentrated HCl into a cup. Extract into
baby syringe until syringe is full (15 mL). NO, the HCl will not dissolve
any part of the syringe in any way.

NEITHER THE HCl NOR THE SULFURIC ACID WILL REACT WITH ANY PIECE OF HARDWARE USED
IN THIS SYSTEM. THIS SET-UP HAS BEEN TESTED MANY TIMES WITH SUCCESS.

7. Insert the syringe into the middle tubing (the one that extends to the bottom
of the beer bottle. End should be submerged in Sulfuric acid.) If insertion
is difficult, use a knife to scrape the inside of the tubing to allow the
syringe to fit more easily.
8. Securing the set-up with a clamp of some sort attached to a stand is optional
but desirable.
9. Have handy on the side a container full of water.


The use of this set-up to gas ones solvent/amine is just as easy.

1. With right hand, hold the tubing that will expel gas and lower into the
solvent/amine solution.
2. With left hand slowly start to inject the HCl solution in the syringe into
the sulfuric acid. Once it hits the acid, there will be alot of fizzing and
foaming and IMMEDIATELY HCl gas will be pumped into the solvent/amine solution.
Foaming is sometimes a problem as it starts to reach the top of the beer
bottle. Simple wait a while and let it settle and then continue. Sometimes
certain brands of drain opener can cause excessive foaming. If this occurs,
switch brands.
3. One syringe is usually enough for an amount of about 30-40 g of product, but
if more is needed after all the HCl has been injected, slowly SLOWLY remove
the syringe from the tubing, first be letting a crack of air into the system.
BEWARE that this is suddenly going to bring a minor rush of HCl from the gassing
tube so make sure that it is submerged when doing this step. To continue, refill
the syringe and proceed as described above.
4. Once the gassing is complete, leave the syringe ATTACHED to the injection
tube and submerge the gassing tube in the container full of water (If the
syringe is not attached to the injecting tube, the following sequence will
not occur). Weigh down the gassing tube somehow as it must remain submerged.
In a few minutes (about five) the sulfuric acid will cool a bit causing a
sucking-back of the water into the beer-bottle. This will happen very suddenly
and very fast, but not to worry as the water will only go in as far as the top
of the beer bottle. This is actually an advantage as in this way one is able
to dilute the remaining HCl gas AND the remaining sulfuric acid. Of course the
bottle will get hot but if left aside for a few minutes it will eventually
cool making opening the container and dispensing with the acid solution an easy
task. If the bottle is opened for whatever reason without the above acid
dilution step, HCl gas will be everywhere.

Hope this method will prove useful to you, it sure has been for me!

I was thinking of a similar setup, just needed to know what chems would do the trick.
Thanks.

Ever try concentrated sulphuric acid heated with table salt?

H2S04+NaCL=>NaHSO4+HCL

if were tlaking clandstine kiss keep it simple stupid, fill a bottle half full of h2so4 thorught in some epsom salt, make a hoseing to run off the cap, bouble that into your honey ,

Um excuse me but..

Epsom salt is MgSO4 -7 H2O, so you add that to H2SO4 and where does the HCL come from?

Salt & sulfuric = bisulfate & HCL

If the acid is concetrated the gas is close to if not completely anhydrous.

Old Hive tale:

Take and old iron or carbon steel pressure cylinder from sometimg like a CO2 fire extinguisher or oxygen tank. Pour in some ice cold water softener salt NaCL and then dump in some ice cold conc sulfuric acid drian opener. Quickly repalce the valve and set the tank into tub of hot water.

HCL gas with pressurize the tank. The H2SO4 & HCL only mildly react with the iron tank which should be thick enough to withstand a little corrosion because it's design operate at pressures of at least a thousand psi.

Obviously you'd hafta do some gas calculations or just take it easy until you have a feel for it. There's obviously a hint of danger involved with this method.

I understand Dyler clearly. I am not stupid. And, I don't make "honey" as you would put it. Meth is bad for the body. Besides, I'd rather trip and gain insight. Meth is definitly not my drug of choice. I considered it at one time though.

mb, but the way we make it is not always the purest, it gets it done, and the boys get rich, i tried crank 2 times, i dont use it, more profitable that way,

Slow down there partener!

All I'm saying is salt and sulfuric make can HCl for whatever purpose.

I'm not advocating the manufacture of meth or any other illicit substance.

I'm just talking about HCL gas and it happens to have multiple uses. So please don't go pigeon holing me into being Dr. Crankenstien.

The whole thing about epsom and acid making HCl is bogus, so in the name of good science I was just clarifying some basic chemical facts and theories.

I was talking to rxrgood4u on that last post. I appreciate your info Dyler. I think you may have misinterpreted my las post. Or were you talking to Rxr? Arrggg.

a bootleg way of getin some hcl gas (this was taken from the hive and not from me... i havent even tested it but it is said to work)
add al foil to hcl and use the gas it gives off. you will need a drying tube as well. also 1 thing this actually produces hydrogen gas (i believe) and the only reason HCL gas is produced is because the reaction is exothermic.. Feel free to correct this if it is incorrect. i just read it.. never tried it. figured i'd post it since it seemed easy to do...

Oh I dunno it was a 'little fuzzy' so I just felt it would be best to clarify my intentions.

With conc H2SO4 and NaCL there's really no need for drying tube. HCL constantly boils at a conc of 20% and fumes at 38%.

If the sulfuric acid used is conc somewhere around +90%.. well there's just not enough water to begin with. The HCL formed will be in excess of 38%HCL and will readily gas out.

I mentioned a drying tube in relation to my post not yours dyler.. sorry for the mixup

I know,
I was just explianing the mechanics in case someone was wondering if you'd always need to dry the gas or not and the reasoning why.

Another side note:

If you substitute KBr for the NaCL it'd be possible to make HBr gas too.

Ohhh I see.. cool.. just wanted to make sure you knew what i was talkin about

Gee, this is REAL weird.
Mr clean changed his gassing setup?
Then he suggests foil/hcl which he's never tried?

Well, perhaps he tried it once out of curiosity and just forgot about it.

Surely mr clean has a picture of his gassing setup (which by the way, seems oddly familiar for some reason...)


Hmmmm....

Slim.

I see that the art of HCl gassing eludes yet another internet bulletin board.
