I need help in precipitating meth hydrochloride salts

[ahmad999]

Hello
After completion of the reduction
I filtered the liquid
Until he became pure then
Then it started to precipitate meth by hydrochloric gas.
Table salt and sulfur acid were used in the production of gas, and the result is as in the video
After filtration, the salts did not come out
After the hydrochloride gas stops, all the salts disappear, what is the problem, please help

Maybe you had too much water in the non polar solvent, did you dry it over magnesium sulfate?

It doesn't look like there is much product to be had. Are you trying to do a .5 gram cook ?
Try to reduce a bigger batch. Try to get it cold before you gas. Make sure the solvent being gassed is dry, and the gas needs to be dry too!
You should see bigger particles gathering and sinking to the bottom. Otherwise what you doing looks correct. Yield is just extremely low I think.

Thank you for your reply
I have a lot of product but I took a small sample of liquid to try with it
I was afraid of experimenting on the entire product so that it would not be lost in its entirety
I'll filter the liquid again I'll cool it down and then poison it with gas.

The solution should be acidic
Use pH indicator paper to confirm the acidic of solution
The solution evaporate to crystallization

When prec, Amph,sulf excess acid will make the salt redissolve. I dont know if it relates to this .....

not applied for HCl, HBr etc., only for polybasic acids as H2SO4, H3PO4 etc.

Too much water in your solution, boil off the water
