Butane vs hexane for large crude production

I’m learning.
Patience is required.
It’s sorta like a titration.
After I get to 50/50 and let it settle, I extract with two more aliquots of heptane.
After that, it’s back in ethanol for some adsorption treatments.
I like to end up in ethanol so I can be sure of stripping off all the heptane.
A little EtOh in the final product adds a bit of taste…

Can one make a full spectrum extract with Hexane? Say from fresh frozen flowers or 10% moisture flowers?

If you include chlorophyll in your particular definition of “full spectrum” then no. Nonpolar solvent gets nonpolar goodies.

Of course chlorophyll is not part of the full spectrum. All i want is to recreate live resin made using hexane instead of butane and understand how I can achieve it. Right now I am working on a system and any ideas would improve my design. I want to know the following things

  • Should I use sub zero temperatures to cool hexane. I can do that by either chilling the solvent or using cool water and running it in a jacket around the reactor

  • Does butane extracts undergo wax removal for live resin?

  • will the product be called live resin if I use hang dried buds instead of fresh frozen ones?

I come from a non-legal country and have limited experience handling cannabis but have done several botanical extractions like green tea.

The issue with hexane extracts (other than the toxicity) is that dewax is very challenging/ineffective.

If you winterize with a polar solvent, it is a great process.

Very cold hexane can make great live resin. A lab i know used to win awards for theirs.

no…

Will fresh buds(moisture level >50%) extract well with hexane?

So rumor would have it…

Thanks for the reply. This is indeed promising. I can bring down hexane to less that 10 ppm limit.

I have personally ran wet bales with Hexane and I can assure you it does not work well. 15 kilos from 1800 pounds. After running the bale and getting such a poor yield I put some material that was left under the microscope. The material seemed to have a gelatinous compound the was encapsulating it. My theory is that it’s comprised of water solubles which would make sense for the low yield. I feel that the pressure of baling causes this. The Hexane simply flowed around everything. Maybe someone else figured it out but it didn’t work well for me.
Saw the same thing with Pelletized biomass.

120c And any anything over -22 in/hg of vac for 4 hours with agitation will get you to 0 ppm.

Very interesting observation Jed!
Were these wet bales considered “properly wet baled” or na? I havent hsv the chance to test process on wet bailed material yet, but planning to do so soon with hexane.

I personally don’t think there is a proper way to wet bale material for Hexane extraction.
Seems that even if they are baled and filled with No2 they still decomposed due to anaerobic bacteria. I feel that the pressure explodes the cell walls of the plant which is bad for guys like me. We did dry the wet bale as well and still had horrible efficiency’s. Maybe if it was dried then baled it might work but from my experience with pellets I tend to think not.

I’ve been around farming most of my life and the one thing we all know is not to bale material wet as its a fire risk as it decomposes. Waters a hell of a solvent.

I havent ran wet baled material but ca tell you when we extract biomass with >10% water we HAVE to add in some methyl acetate to the hexane or our yields drop.

Do you leave 1% in the material on average? I see anywhere from 1.3% to .65%.

Were usually right at .5% total cbd in the biomass after extraction.

Your doing better than I am! is that using a centrifuge? I saw an increase in the CBD remaining once I switch to the centrifuge. I used to see around that when I was doing a second quick wash. Quantity was higher but the quality went down.
