Applications of a High Pressure Soxhlet Extractor Using Liquid CO2 for theExtraction of Organic Phosphonates from Solid Adsorbents

摘要

The feasibility and efficiency of extraction of various organic phosphonates fromdifferent adsorbents was studied using a soxhlet extractor enclosed in a stainless steel canister. Liquid CO2 was used as the solvent The CO2 was introduced into the sealable cylinder, and the entire unit was pressurized by vaporizing the CO2 with slight heating, and condensing the vaporized CO2 on a cold finger.
