If youre able to use a flammable solvent like pentane then I’m sure you could use butane. Butane or bust…
Ethanol and pentane may be slightly soluble, where as methanol and pentane are insoluble.

I know people running a method like this and getting fantastic results. Except using methanol and then LLE into pentane once mostly evaporated (rather than completely evaporated).

I made a ton of sauce like this
Sounds interesting…do you know if they capture the entire profile and terpenes with this method?

I don’t really have any test data, but they made sauce/HTE and it was as delicious as the butane ones i’ve had.

Pentane dryacetone for the win

What order? I was thinking Dewax in acetone, Rotovap, then re-dissolve in Pentane to process further.

Dewar in acetone
Distill solvent cold 80%
Pass treu dried epsom salt
Add pentane boil of azeotrope pentane/acetone at 32C
Have it all in pentane
Pass treu bentonite evap pentane till 5%
Oven

Will -40 etoh to evap to pentane than evap produce a terpy shatter the same as butane? This may be an easier route for people as alot of guys already has centrifuges or pandas and they can just run a super cold etoh > evap > pentane 8:1 > evap and oven for etoh/pentane slabs
Will this have a terp profile as good as butane?
No I don’t think so. You’re still removing ethanol on the rotovap at 38C under reduced pressure. There are azeotropes between mono terps and ethanol, such that the mono terps will boil with ethanol during your rotovap step.

What about methanol with the low bp as replacement for etoh to obtain high terpene profile with the pentane?
You’re asking if you can extract with methanol? Wtf?

No im trying to keep the terpene profile intact ane avoid the azeotropes of etoh.
So heptane warm > methanol dewax warm > evap > 8:1 pentane > evap
Would this result in high grade shatter similiar to using butane? Goal is to make perfect shatter without the use of a CLS system

Here’s the pros talking about methanol extraction
That’s what my friend did as i said above, with very good results

Realize that it s hard to get the noids from heptane to methanol
But easy to get them from methanol to heptane

We have also had better results with methanol not codistilling with terpenes but it does still happen. I have some buckets of methanol teprshine that smell fucking amazing lol. Stop smelling that, you’ll go blind

But i want to use heptane for initial extraction as I can do it warm and not worry about chloro.
What do you think is best route?
heptane > methanol > pentane > terpy/fire shatter?
