Synthesis of Rosin Pentaerythritol Ester under Microwave Heating Conditions
摘要
Abstract
An etticient and rapid method of synthesizing rosin pentaerythritol ester is described under microwave conditions in a closed system.Conventional heating process of rosin esterification needs 270 min.This unprecedented synthesis improves the performance of the products significantly and reduces reaction time to 40 min.Furthermore,an orthogonal test of L9 (34) was also designed in order to study factors which affected the color and acid value of the products.The optimized synthesis conditions are as follows:the dosage of BEP,0.30％ ; the dosage of pentaerythritol,16％ ; heating time,40 min; microwave power,200W.The rosin pentaerythritol ester with light color (Gardner 4),low acid value (12.7 mg/g),and high softening point (102℃) was obtained under optimized conditions.关键词
