Methanol for winterization

i would be interested to know who is extracting with methanol as well. would be pretty sweet to extract, filter and winterize with the same solvent without dry ice or ultra low temps.

I dont extract at all anymore, only distillation

Extraction is too messy to use methanol for in my opinion. But if you have a fully enclosed system it would be okay

I would never extract with methanol, even at cryo temps because of the polarity you’ll pull chloraphyll

I extract with methanol not always but often
clorofyl is not an issue at cryo temps
biggest drawback are sugars you pull a lot of sugers that hurt when distilling
I am doing some test right now to see if I can pull them out before distillation
brine washing
any suggestions welcome

Maybe washing with water? Or a less than fully saturated brine solution?

yes I am washing with water and louching with different alcohols
have 250 ml of each will spd each and see wich leaves a flask without some black glass tar behind
it s really old weed but some are stuck with it see if I can make something that will set them free

does excess sugars cause any other problems to distillate other than the residue on glass?

no not really it starts to darken your tails a little more
it s a pain to clean the glass
and this batch is so large I want to pull it on a wiped film so I want it to be as clean as possible

I would think that a brine wash would take care of the sugars rather easily. Since a brine wash is usually performed on crude that’s headed to distillate it kind of makes more sense to just extract with cryo methanol.

That way you really dont have to winterize the solution and your solvent is much cheaper and more recyclable too because it doesnt form an azeotrope with the water your going to pick up during extractions. You get to skip the long step.

But if your going to be extracting with methanol you should probably make a triclamp rig to minimize exposure to the vapors.

if only you knew I will post my extraction facility in the mountains this summer
it s a madmans heaven https://www.cdc.gov/niosh/mining/UserFiles/works/pdfs/tloca.pdf
it s a hyperbaric room of 8 x 6 ‘’ with a co 2 nitrogen enriched atmosphere wich is cooled to -5C
oxygen level around 2 percent and sort of like a tube snorkel as breading apparatus
2 x300L wash buckets and a 20 kg atex centrifuge
methanol and butane are the only solvents used hmmm I hear you thinking
4 x-86C freezers made in the walls for storage of biomass only the doors are in the room the compessors are out the cooling unit is atex and everything is grounded
it still ain t safe but at least I am doing what I like most if shit hits the fan

anyone know where to find methanol in LA?

Check performance car part stores or shops that specialize in diesel engines. Methanol is often used in drag racing and methanol injection for diesels.

i got it from an RC car place

distilled it yourself to purify it or is it good to use straight out of the jug?

expensive?

i think i will do this at room temp, then chilled. then brine/hexane wash for sugars, water solubles, then distill
