Chlorophyll Is the green color found in most plant based extracts. High molecular weight and high boiling point makes chlorophyll easily removed by distillation, but the polar nature of the molecule also makes it easy to separate with other techniques that take advantage of differences in polarity such as liquid to liquid separation. Exposure to…
Purification by Altering Solubility (Winterization)
The process of removing waxes, fats, and lipids in general is often called winterization or dewaxing. When a solvent has several compounds with differing solubility you can remove the least soluble compounds by decreasing the solubility of the whole system. Altering the temperature, differences in polarity and agitation are ways to manipulate solubility and each…
Degradation
Because cannabinoids themselves have a high boiling point and would foul or degrade when exposed to high temperatures vacuum is applied to lower the boiling points. If you are not able to achieve a deep enough level of vacuum whether through leaks, poor vacuum pump performance, or other ways the temperature needed for distillation to…
