If my hydro extraction is crc’d and is dewaxed do i need to winterize before spd?

Pardon my ignorance but what do you think is the difference between dewaxed and winterize?

Loool
Id assume he means inline dewaxed via closed loop, vs actual polar solvent precipitation of lipids. As a guess.

Correct
Yes, winterizing will help with purity and possible cloudiness of distillate after spd. 48 hours at -20C is the standard. You can do it for 24 hours, but you’ll need a good freezer (-40C to -60C).

Thanks! Ill be using dry ice to speed the process.

Required? No.
Desirable? Probably.
Best way to find out?
Actually winterize some and see what you pull out…
Why? Because your “inline dewax” is undoubtedly going to be different from anybody else’s…
(did you list extraction, CRC, or dewax parameters? No. So HTF does anyone know exactly what you’re doing?!?).
Distill some of each and get it potency tested.
Some winterize between first and second distillation…others don’t winterize and just send it after a single pass.
What scale are you planning to achieve this?

Or you could use methanol and get it done in a wayyyyyy shorter time then that. I do 6:1 methanol to crude and filter it once it hits -20c which takes 4 to 6 hours max
Ethanol definitely will take longer because you have to go colder but from my experience you dont really need to let it sit.

OOOO exploiting lower heat capacities is a great idea. I filtered once a week, so I always let everything sit for a while and accumulate for ease of use.

Solid suggestion for folks who know what they’re doing, and are doing it at scale.
Not sure that’s our OP.
If endpoint is distillate (as stated), residual solvent should not be an issue.
However, if this is essentially an “at home” operation (my impression, which certainly could be wrong), then it is unlikely OP has the appropriate knowledge or equipment to use methanol safely and is better off using ethanol (imo)
that could be changed…
Care to share the risks involved and how you would mitigate if doing this with basic tooling (eg open buchner)?
It’s not…but if you swallow it doesn’t take much

Agreed, Acetone and Isopropyl work within 24 hours at -20f as well.

Ah so K.O.T.K. has been drinking methanol. That explains a couple things
You do realize you drink methanol everytime you drink any kind of alcohol right? Even food grade ethanol has methanol in it and sometimes even isopropyl
And all it takes is drinking some ethanol to prevent it
If you go to the hospital for methanol poisoning theyll literally give you ethanol to counter it.

You edited your comment while I was typing to make it less retarded*

Doesn’t matter you’re still drinking both methanol and isopropyl anytime you consume food grade alcohol
And btw it doesnt produce formic acid like you said in your edited comment
Lol
Yes. I do. (Along with an appropriate “antidote”. so that snippet is irrelevant unless you drink ethanol while working in lab…)
Point is @Kwad1298 or any of the next 100 viewers might not.
So it would be irresponsible not to point out the LD50…which is about 1000 times more than cyanide and ~10x lower than ethanol.
How does that change: “10-30ml of methanol can kill you”?
It doesn’t.

Can you explain why?
It’s not because ethanol inhibits alcohol dehydrogenase…
Its through competitive inhibition
Its giving the enzymes somethings else to break down instead of the methanol so the methanol can be passed without being broken down. Ethanol has much higher affinity than methanol which is why it works.
Fomepizole actually works the same way it just has 8000 x the affinity for the enzymes compared to ethanol
