Chlorophyll crude

Crude to distillate

You can clean up any extract very well by boiling it first in 70/30 iso/water rubbing alcohol. This will cause any green chlorophyls to swell up along with the waxes which get denatured too by the alcohol. Iso and water form an azeotrope so the iso will not boil off completely at first but the mix will become a higher percentage of water as you boil it off. Extract will drop out of solution as the percentage of water increases and you will be left with an emulsion of water and compound. Putting …

Getting out the green

Here is a great shot. The terps have already been removed via liquid to liquid extraction. Starting compound was dark brown. Compound was boiled in isopropyl alcohol and water after the LLE to remove terps then cool to room temp. Waxes were removed over alumina. Mixture was transfered into a cryogenic bath held at -85C for several hours. Then another alumina column was prepared and packed under vacuum using 70/30 iso to water rubbing alcohol. At that point the cryogenically cooled terpene free …
