Dissolved freebase in IPA, dripped in HCl 31 % till pH acidic ( tried to hit 3, but easy to overshoot, I got pH = 1 or a bit less ) then let it dry, when sticky, added acetone. Crystals precipitated. First batch xtalized exactly same way. I also overshot the first one. I think the acetone removes the extra HCl, not exactly sure about it though.
Yes, also seen a tiny bit ( in fact almost white, even when looked over paper ) of yellow, if you shake the flask xtals move easily, but slighly sticky, xtals.
Not my idea, have seen it posted on the Hive before.
I haven't seen the capsules dissolve yet ( I have just two 0, two 3 sizes I am watching right now ) if they do I will post.
Thanks, W.
