中文摘要：首先将桐油与甲醇经过酯交换反应制备桐酸甲酯,然后在浓硫酸的催化下将其与过氧化氢和乙酸反应,制备环氧桐酸甲酯,最后以阳离子光引发剂(三芳基硫鎓盐)为催化剂,在UV光照条件下催化环氧桐酸甲酯与二乙醇胺进行光化学开环反应,制备桐油基多元醇。并通过红外光谱、紫外光谱、核磁波谱、凝胶色谱等方法来鉴定产物的结构。结果表明,在UV光下三芳基硫鎓盐可以催化环氧桐酸甲酯开环制备桐油基多元醇,其羟基值为599.54mg KOH/g,平均分子量为544。

外文摘要：In this paper,firstly,the methyl eleostearate(ME)was prepared via transesterification of tung with methanol,then epoxidized methyl eleostearat(EME)was synthesized via the reaction of methyl eleostearate with hydrogen peroxide and acetic acid under the catalysis of concentrated phosphoric acid.Finally,the tung oil based polyol(TO-based polyol)was acquired through the reaction of EME with diethanolamine(DEA)using cationic photoinitiators(triarylsulfonium salts)as catalytst via ultraviolet photocatalysis.The products were confirmed by the characterization results of Fourier transform infrared spectroscopy(FT-IR),ultraviolet-visible spectroscopy(UV-Vis),nuclear magnetic resonance spectroscopy(NMR)and gel permeation chromatography(GPC).The results showed that TAS could catalyze the ring-opening reaction of EME with DEA under UV irradiation,and the hydroxyl value of TO-based polyol was 599.54 mg KOH/g and the average relative molecular mass was 544.
