He(swim) thinks he understand the a/b washes.(duh) He has had 3 sucessful runs. He was only trying to understand HOW he got crystals as he had nevr done this before in his fucking life, with little more than a writeup to go by. NO he is not a (chemist) but I was kinda proud of him anyway. He DID do the rest of the steps on some and it seemed to mess it up. He didn't know why.(ph likely was off)
Well, he did and has been reading a lot for the past 3 years. He just doesn't post very often. Something a lot more people should try, obviously.(don't take that wrong) I know, a why the hell didn't you get oil instead of crystals search. Obviously it's over in the Meth section. How stupid of me.
The paticular step said " a light brown precipitate will fall out" and it was indeed that but only it was allready in a crystal form, hence the confusion. He tasted and liked it , what the hell. He wasn't sad about it. It's no big deal. What ta fu
I think from what I'm reading here though is Mr . M's wasn't good . I'm not sure but swims was. so he thought it was a good thing. Your right, he doesn't know.
I like the sound of the chilled acetone thing. Nice and slow. (saw that from a search he did)
He did have sucess with BS recrystaisation and it Was quick,as you said. And he did notice that no matter how many acetone washes it never came any purer ( a slightly yellowish or light brownish)
He does not use hcl and gas and all that because it's not in the BS synth. and that is the only reason other than availibility reasons and all that. It's simple, only make sure there is absolutely no water in the mix or you get crapola as they say.
