If I follow the RSO recipe from extraction to distillation and finish with my oil. Can I let the oil cool and then add acetic anhydride to the oil and distill the acetate. I am thinking this should change the THC to THC O-Acetate. Then wash the product with chemicals and a separatory funnel. My goal is to take THC (oil) and turn it into THC O-Acetate (WATER SOLUBLE) so I can administer as a suppository. The THC O-acetate is water soluble and will pass through the membrane of the sphincter, where the THC (oil) will not pass through the membrane wall as well because it is a fat. Thanks for the help.
