Two methods for refining THC distillate, one a Liquid Phase extraction (LPE), the other a Solid Phase extraction (SPE), are presented. The LPE is performed with the distillate suspended in a non polar alkane, then washed with a range of pH balanced saline. This both extracts the water solubles and buffers the solution for proper adsorption during the SPE. The solution is then passed over a chromatography column loaded with MagSil-PR. The alkane is then recovered and the distillate is distilled a second time. The resulting distillate passes PPB residual testing for most common pesticides, specifically Myclobutanil.
