Im a trying to figure out how to distill my solvent (40 butane, 40 isobutane, 20 propane). The label says its 99.97% pure but I heard I need to distill the solvent regardless. I currently have the solvent tank hooked up to my collection pot. The collection pot is in ice water. The collection pot gauge is reading 40 psi. A little bit of solvent has come out but it stopped. What am I doing wrong? Or what else should I do to get more solvent out?
Sorry if this is basic but Im brand new. Any advice is greatly appreciated.
