ABSTRACT:
The extraction process includes supplying solvent under gas pressure for introduction of the solvent adjacent the bottom of a vessel containing the sample. The vessel lies in a water bath and ultrasonic energy is applied to the bath and hence to the sample to facilitate interaction between the solvent and the sample. Because the solvent is immiscible in the sample and of lesser density, the solvent and solubilized material rise to the top of the vessel. An extraction tube under vacuum pressure continuously removes the solvent with the solubilized material.
