I’ve always wondered how running a hot solvent vapor would work for terp extraction. Basically just distill your solvent through a packed material column, then recover the solvent with as low of a temp as possible.
Edit: I also imagine you’d want a jacketed column that you could heat too.
I wonder if DME would work well for that application as well. Or chloroform maybe. I feel like pentane might still be too close in properties to a lot of our desirable compounds than is ideal (then again that’s probably why “steam” distillation works well with them)
Right, likely to lose the goods while purging the solvent. I had never heard of it being pitched as a butane alternative till you said that lol.
I thought DME was immiscible with water but I must have been mistaken, I imagine that’s a useful property for this method to allow using fresh frozen/fresh material.
“Diethyl ether is miscible with water only in small amounts (up to 6% or so).”
If I’m off base here correct me haha. Not a scientist by any means.
Google again in regards to DME:
“Dimethyl ether (DME) is a synthetically produced alternative to diesel for use in specially designed compression ignition diesel engines.”
