摘要

Procedure for obtaining the Treo dihidroxioctadecanodioico 9,10 - acid -, I -, acid - and Treo 9,10,18 trihidroxioctadecanoico, II, from Cork. The Cork is subjected to alkali metal and Alkaline metanolisis with excess Methanol, during a period of time that varies between 4 to 6 hours, hot or cold days.The filtered Liquid is Evaporated to Dryness and The residue dissolved in acetic acid undergoes a Trans hydroxylation adding Hydrogen peroxide and concentrated sulfuric acid, at a temperature of 40 025 45 - C for 3 to 5 hours.This is the solution with boiling water, producing a precipitad cooled undergoes a saponification by dispersion in water and addition of alkaline hydroxide heated to reflux for 3 to 5 hours. Hot filtered to separate the solid not dissolved and filtered by acidification with mineral acid precipitates a Crystalline mix of acids to obtain.
