Title: Anyone making THC extract with propane?
Post by: BlarghRawr on March 25, 2012, 03:08 am
I know it is possible, probably the only concern is the purity of the propane. I also know it is safer, far safer even, than BHO. Propane is non-toxic in the human body, and given that it has a lower boiling temp [around -40 c], it should leave less residue behind anyway. I would like to suggest that someone look into this, if nothing else.

ive wondered that before too ive also wondered if you took a 20lb co2 tank and regulator n tubing n a glass bho tube of trim and made a bho style product in theory the gas would freeze your trichomes and then push them out through the force of the gas expelling from the tank. i thought it would work cuz making dry ice hash is basically the same process but with out the shaking. just a high theory

I used for extraction mix of absolute alcohol and di methyle ether in proportions 6:1. 15 minutes at room temperature. if you will keep longer it will not improve extraction, but will increase amount of unwanted substances in extract, like chlorophyll, beta carotin and others.

for 250g of dry weed take 450ml of solvent, keep in solvent for 15 min, then filter and recover solvent by distillation with condenser. no heating more then 90C.  250g of dry weed will give about 1.4 g of extract.
