So all was well until the crude was burnt from going in and out of vacuum, deceases last night for today’s run and boom smoking when I turned on the vacuum today. So now all the glassware just reeks of this horrible burnt rubber smell.
Please help me rid this smell it’s taking over everything
I’m not an expert on glass and def double check this method bc I have not done it. Heating a solvent close to the temps you shut off the SPD. Maybe the glass captured the “stank” when expanded and when cooled down it’s stuck in the glass? This is a guess don’t take my word on it.
Agreed now I need to know how to remove the stank it’s so overpowering
going for a first pass you should have de terped better on decarb or decarbed in a rotovap and maybe tried liquid liquid extraction with methanol to pull water terpenes out and maybe better winterize more then once pre processing is easier then second pass to remove stink
what temps were you hitting do u have head temp mantle temp logged
a little more info on your setup like a pic and a breakdown on your process to get to this point would really be helpful i’m not an expert by any means just trying to help
Ventilation and ozium . Been there . Fresh air is your best friend
Sorry I was referring to from the glassware, no head temp because I am using a summit head and a key in it, hitting mains at 187 in the boiling flask at 300ish microns but turned it up to 190 just to be safe on because the high reading, but got to 200 halfway through mains, my vacuum connections are gl14s as well
The events that happened to the smoking of crude. decarbed at 130c for 60 mins decided to wrap up for the day and broke vacuum, pretty fast. Get in the next day and pull a full vac. BOOM smoking.
was it winterized crude?
Did not see any wax’s precipitate when chilled at -22 for over 24 hours and was filtered
Sounds like you extracted with alcohol.
Winterizing will not solve this problem
This is my “burnt” SPD cleaning SOP
Or if you have a sonicator
Bleach is my go-to when things are stanky. Oxidizes the smelly compounds. The oxidized compounds typically smell less bad but not always
be careful using a sonicator with glassware that is meant for distillation, the sonic waves can create micro fractures in the glass. A previous vacuum jacketed distillation head that I had lost its vacuum from those fractures.
What companies glass? If you don’t mind me asking
It was my old 2L Lab Society head, I could still distill with it, I dont think that the fractures caused any substantial weakening of the vacuum (though maybe after prolonged use it might?) but the head began floating in water instead of sinking to the bottom, so I knew something was up. Mr. Summit man mentioned this also, I’m just being extra careful with our distillation equipment now, still use the sonicator for other glassware though.
Have you seen a decrease in efficiency? If the jacket now has air in it you would expect it to insulate differently
This is not remotely cold enough. Needs to be atleast -40C. On top of that if your using alcohol you probably had it to diluted. Did you wash And then go straight to winterizing? You have to remove a solid amount of ethanol after soaking before going to winterizing or it’s going to be way to diluted to precipitate fats even if you were cold enough.
@Siosis
It was diluted 8:1 and I have seen room temp 190 proof precipitate fats, in bho, but maybe I should of gone colder
