Soooo I never have issues cleaning up azulene. But suddenly we had to buy distillate instead of buying crude and distilling it ourselves, and this batch of distillate had THE MOST azulene come over that I’ve ever seen and now I’m unable to seperate it out after even 3 passes in a SPD.
So going to try methanol dissolved mag sil flush, maybe some LLE, just throw the book at it I guess. But I’m at a loss as to how this could happen (the distillate was made from the exact crude we normally run, just our supplier distilled it for us this time instead of us distilling it. So I’m guessing some sort of wierd PH issue with their process?)
Anyone have good ideas on how to clean this shot up?
We usually use our volatile pass on our wiper. Was that crude you purchased THC free or thc complaint? I know the conversation process THC to CBD creates a lot of azulene.
Dont use methanol with magsil, definitely incorrect. Hydrocarbons are what make magsil work. I have a post about it called “because i can”
Beyond that, magsil may or may not remove the blue fraction.
If you keep repeating spd runs, then i would say try a bump trap to remove it. 24/40 “bump trap” from precision labware. Very precise and just use an adapter for whatever size flask opening you have. The 24/40 works best to remove just that pesky heads fraction.
