Hi, guys.
Not a chemist, but somewhat chemistry "aware".
If the goal is to eliminate chlorophyll in RSO, I believe one has to look first at the solvent being used. Most commonly, ethanol or propanol. Unfortunately, these alcohols are "partially" polar, meaning polar molecules like water and chlorophyll will also dissolve into solution. I use the "winterized" (bud and solvent frozen in freezer) technique as it also helps reduce waxes and lipids dissolving into solvent.
Rick Simpson also used "light" naptha, which is non-polar. Butane, hexane and heptane are also non-polar possibilities, but much more dangerous due to flammability. A real lab set up (exhaust hood, distillation glassware, etc.) would be a MANDATORY safety requirement! Terpenes are also non-polar and should dissolve into non-polar solvents, but not water.
Your thoughts?
