Question What to do now with mdma freebase mixed in acetone (after total failure with HCL gas)?

[workworkwork]

I mixed about 800 ml mdma freebase in 8 L cold acetone. I was then supposed to acidify with dry HCL gas, but was a total failure, not 1 bubble from HCL arrived the flask with the mdma freebase in acetone...
Can I keep the freebase in acetone in the freezer or does it deteriorates?

My setup were 3 plastic buckets connect by plastic tubes. The plastic bucket number 2 was an empty bucket, a trap, if the freebase on bucket number 3 got sucked.

In the first bucket I put 800g of calcium chloride. I put the lid on the bucket and through one of the previously prepared holes I poured muriatic acid. There was no reaction! Not 1 gas bubble in my mdma freebase in acetone.

Interesting segment conveniently start at 4:20
No need to get fancy, using not dried hcl gas will yield product still, focus on getting that down than maybe think of adding drying tubes to your working solution.

But that is with sulphuric acid? I was trying dry the HCL with calcium chloride and didn't work. So, I added the muriatic acid directly in the mdma freebase in acetone till PH 6-7 and put in the freezer.

You cant dry HCL acid with calcium chloride.

CaCl and HCl(aq) do not react to create HCl(g). Also to dry the gas you would need to pass it through the drying agent not put it in the reaction. You can do H2SO4 and dry NaCl (or CaCl if you really want to use it) to produce the HCl(g). MDMA should be able to sit in acetone no problem as long as there isn't other chemicals in your solution. Adding HCl(aq) to your solution will cause the salt to form; however you also added a bunch of water, which your MDMA is going to be soluble in. You may have some product precipitate in the freezer, but most will stay dissolved. To put it nicely, you kind of fucked up lol. I am going to presume you don't have a rotovap or even a vacuum pump, so my best advice for you is to get a electric blanket, a large dish and a fan. Pour all of your solution into the dish (you can do it in portions if it doesn't fit) put it on top of the electric blanket and blow your fan on it. Put it outside or somewhere the fumes can escape, and you are going to wait for it to evaporate. The fan and the gentle heat will speed it along. If you heat it too much it will decompose. Be patient. After all of your solvent is gone you will be left with a residue of MDMA HCl.
Best of luck

Yes, I have distillation equipment and a small vacuum pump I bought from ebay for 12 euros 15l/min. I don't need the electric blanket! And I already collect the mdma that precipitated.

Now I have the mdma mixed with water in acetone. I will distill the acetone and after that I think the best method is make an acid-base extraction?
First I will mix the dirty solution with water, non polar solvent such as methanol and hcl. The mdma salt will dissolve in water but not in the non polar solvent. I remove the methanol layer.
After that I add water withNaOH and methyle chloride, the mdma freebase will go to the bottom together with the methylene chloride and I remove the water layer.
I'm studying the acid-base extraction, is this correct?

You could try a vacuum distillation to remove the acetone instead then. Your pump is pretty weak but it will help a little.
An acid base extraction is a viable option. Methanol is miscible with water so it will not form a separate layer. If you have DCM it will work, but not methanol. You will have to remove all the acetone, add DCM to your water and separate it after to remove any impurity. Add NaOH and more DCM. Now the MDMA will move to the DCM layer. Evaporate off your DCM. Redissolve in IPA/toluene or some other solvent that you can pass your HCl(g) through. Then filter your product.

I did evaporate acetone from acetone-FB mixture. It is not more difficult than evaporate pet ether after base extraction. And boliling point is less.

If you are not sure about how to gas it properly, you could just use the acid and a small amount of dH20 to get to pH 6-7 and let the water evaporate slowly to get your MDMA HCl. A non-polar solvent (Toulene, Xylene, DCM etc) would keep your freebase well disolved and to this you add the HCl (after proper cleaning/washing of the freebase) with basic/water, brine or however you decide to perfect it ad needed.

Or you just gas it. Honestly I never used gas on Acetone with freebase in it but with Xylene and Ether a lot of gassing has been made. Both ways are acceptable unless you are in a hurry or something.

Kind regards,
