Can you Use Hexane for Oil Extraction - Oil Extracting Solvents

In this method of oil extraction, a low toxicity chemical solvent, such as hexane, is mixed with the product that oil is being extracted from. The plant product sits soaking in the solvent allowing the solvent to pull the oil from the seed or plant. After the oil has been successfully extracted, heat is applied to boil the solvent and plant mixture, allowing the chemical solvent to evaporate

CBD Oil Extraction Methods - How Are They Different? - CBD

Liquid solvent extraction most commonly involves the use of ethanol. Butane, isopropyl alcohol and hexane are other liquid solvents that are sometimes used. In the liquid solvent extraction process, no specialized equipment is needed. The plant material is placed in a container and the solvent is run through it which takes the CBD from the plant.

Pros and Cons of Co2 Extraction Method vs Ethanol Extraction

Ethanol extraction typically destroys the terpenes when the ethanol is removed from the extract or is distilled from the winterized oil. Many ethanol extractors are seeking a way to preserve the terpene profile of the plant in the output oil. To this end people have tried techniques such as Steam distillation, CO2 stripping, and vacuum distillation.
