PRODUCTION OF ALKYLENE OXIDE ADDUCT TO ALKYL ESTER BY ADDING ALCOHOL

摘要

A manufacturing method of an adduct of alkylene oxide by adding alcohol in alkyl ester is provided reduce the product cost and improve the product quality of adduct without additional process. A method for manufacturing an adduct of alkylene oxide to alkyl ester comprises: a step of putting a catalyst and alkyl ester in a reactor and heating at 100°C-180°C; a step of inserting alkylene oxide in the reactor; a step of lowering the temperature of the reactor, discharging remaining pressure of the reactor and putting alcohol; and a step of reheating the reactor at 100°C-180°C and inserting alkylene oxide. The alkylester is fatty methyl ester, methyl meta acrylate (MMA) or triglyceramide. The catalyst is NaOCH3, NaOH or KOH. The manufacturing method further comprises a step of maturing after the addition reaction and a step of neutralizing after discharging adduct.
