A/B extraction with hydrogen cloride
Thanks for reading,
Just wondering on the a/b extraction process.
Take my psuedo after gakk removal procedures, make the psuedo basic at ph 12-13 then of course extract the water with my epsom and let dry.
Here's where i need a little help...add double psuedo volume with toulene right?? Then gas it with hydrogen cloride(how long...any clues to stop) and see the snow storm....then seperate the toulene and the crystals should form, correct? Then wash with dh2o and siphon off top and let dry into once again crystals?? Is that clean enough? maybe wash a couple more times??
Thanks again for any input you can offer

Re: A/B extraction with hydrogen cloride
this i have done! what they mean by white snow storm!thats what it will do but the soulution actully gets really thick like matter the white solution that forms, forms to settle at the bottom of course it gets thicker and thicker and than ofcourse when the reaction is complete you filter it and your meth stays in the filter and the liquid is discarded
