摘要
以松香和环氧乙烷为主要原料合成松香聚氧乙烯醚非离子表面活性剂,通过羟值的分析,探讨不同催化剂、反应温度、压力对环氧乙烷加成数及断链的影响。
The synthesis of polyoxyethylene with rosin and ethylene oxide was studied. Applied hydroxyl value as a indicator, the effect of different catalysts, reaction temperature, pressure on the adduct number of ethylene oxide were observed and discussed.
