I just prefer to not evaporate solvents, but that takes extra time. I would use a gravity filtration though in both cases though. It's just as fast and doesn't have as many problems as a vacuum one. Still do a recrystallization though. Without a recryst/hot filtration, the ASA is still pretty dirty. Hey guys, today we are
