Resinous compound crystallization using non-polar solvent sequence |
| abstract |
A resin containing a desirable compound is extracted from plant material and dissolved in a volatile non-polar solvent. The solvent is evaporated, cooling the solution and increasing the saturation level of the compound in the solution. A second volatile non-polar solvent, in which the compound is less soluble, is then added to the solution and evaporated. This again cools the solution and increases the saturation level until the compound has started to crystallize. The crystals are then filtered and rinsed. Crystallization is more rapid compared to traditional techniques. The resin is obtained from the plant material using an extraction solvent to form a solution, which is then floated above an immiscible liquid, where it is drawn off through a screen and the extraction solvent evaporated. |
