This is the fora you're looking for. Also the
BLAB tek goes through some more details and conversion steps.
When you pull with xylene/toulene/d-limo and you don't want to evaporate, you need to "salt" the alks out.
Basically, when you do a xylene pull, your alks are freebased so they will stay in the solution until you add an extra salt molecule. The salted molecules aren't soluble in the xylene.
You'll need to get some fumaric acid, there is a great shop in the supplier section, use the search feature. You'll also need some acetone and some epson salt. You'll bake the epson salt and add it to the acetone to get any excess water out. Then you'll saturate the acetone with the fumaric acid and add it dropwise to your xylene pull. The slower you add the FASA, the cleaner your end product will be. You'll end up with DMT-Fumarate which is great for oral trips with an MAOI. If you want to smoke your end result, you'll need to freebase the alks with some sodium carbonate.
Research that fora and you should be good to go. Good luck
