FREMGANGSMAATE VED UTSKILLELSE AV FETTSYREESTERE FRA EN TILFOERSELSBLANDING OMFATTENDE FETTSYREESTERE OG KOLOFONIUMSYREESTERE.

摘要

An ester of a fatty acid is separated from a mixture comprising an ester of a fatty acid and an ester of a rosin acid by contacting the mixture at adsorption conditions with an adsorbent comprising silicalite, thereby selectively adsorbing the ester of a fatty acid. The fatty acid ester can be recovered from the adsorbent by desorption with a desorbent material comprising a paraffinic hydrocarbon. A simulated moving bed counter-current flow adsorption systemn can be used.
