Abstract
Continuous, countercurrent flow, fluid-solid contacting process for the separation of more unsaturated fatty acid ester from a less unsaturated fatty acid ester in a mixture comprising the two types of esters. The solid adsorbent utilized in said process is a Type X or Type Y zeolite containing specified cations at the exchangeable cationic sites, and the desorbent is a mixture of a paraffinic hydrocarbon and an ether.
