Apparatus for continuous extraction: Its application to the determination of unsaponifiable matter in fats and of total fatty acids in soapstock

  • Published:
Oil & Soap

Abstract

The apparatus consists of a pipette-like glass tube (solvent distributor) into the side-wall and inside of which is sealed a somewhat smaller tube for carrying solvent vapor. This device is supported in a test tube, the sidearm of which is connected to a distillation flask containing the solvent. The solvent distills from the flask through the tube, is condensed in a condenser, runs down the inside walls of the distributor and accumulates in the test tube until its level reaches the sidearm, where a portion overflows back into the solvent reservoir.

Data are given comparing results obtained by official methods with those obtained using the apparatus described.
