Hi!
After swim finished the DPT synth ala shulgin he purified it severel times via A/B. The result was still a brown viscious liquid(the HCl salt) and no nice crystals. What do you suggest to purify it? Recrystallise in acetone perhaps? Or is it essential to vac distill it?
If so, what kind of vac should be used and what temps?
Thanks
Regards
