摘　　要：以丙烯酸松香、聚乙二醇、蔗糖合成了一种新型的松香系列非离子表面活性剂 ,用IR谱、TGA谱进行结构表征 ,对其表面性质进行了测定及探讨。结果表明 :在合成反应中 ,中间产品的最佳控制条件为酸值≤ 6mgKOH/g ,溴值≤ 2 84 5mgBr2 /g。中间产品的n(PⅡ)∶n(蔗糖 ) =1 0∶2 0 ,w(复合催化剂 ) =2 % ,反应时间 6 0h ,各阶段反应温度分别为 2 2 0、180、10 5℃ ,产率为92 5 %。A new type rosin series of non ionic surfactant was synthesized by acrylic acid rosin,polyethylene glycol and sucrose.The structure of the product was investigated by IR spectra and TGA spectra and the surface property of the product was determined.The results showed that the best control conditions for the intermediates were acid value≤6 mgKOH/g and bromine value≤284.5 mgBr\-2/g.Intermediate P\-Ⅱ/sucrose (mol ratio) was 1.0∶2.0.Compound catalysts with trace amount of I\-2 was used.Ratio of compound catalyst to reaction material was 0.02 (w/w),reaction time was 6 0 h,and reaction temperatures in three stages were 220,180 and 105 ℃.The yield was 92.5%.
