摘要: 研究Gemini磷酸酯表面活性剂的最佳合成工艺。以正癸醇与环氧氯丙烷为原料在相转移催化剂存在的条件下合成Gemini磷酸酯表面活性剂的中间体I—正癸基缩水甘油醚,讨论催化剂种类及用量对反应的影响;以乙二醇和正癸基缩水甘油醚为原料,金属钾为催化剂合成Gemini磷酸酯表面活性剂的中间体Ⅱ—正癸基低聚二醇,讨论催化剂种类与用量对反应的影响;以P2O5与正癸基低聚二醇为原料合成Gemini磷酸酯表面活性剂,讨论投料比、反应温度和反应时间等因素对反应的影响。实验选择苄基三乙基氯化铵为催化剂,用量为4%,投料比为2∶1,反应温度为60℃,反应时间为6时,最终产率为78.3%。

Abstract: This paper studied the optimal technology of synthesizing the Gemini phosphate surfactant.The intermediate decyl-glycidol ether(I) of Gemini phosphate surfactant was synthesized with decanol and epichlorohydrin in the presence of phase-transfer catalyst;the intermediate decyl digomeric glycol(II) of Gemini phosphate surfactant was prepared by opening ring reaction of decyl glycide ether and glycol in the presence of potassium as catalyst;and the influence of type and dosage of phase-transfer catalysts was studied.The Gemini phosphate surfactant was synthesized with decyl digomeric glycol and phosphatizing agent P_2O_5 by phosphatizing.The influences of the ratio of reactants,temperature and time on the reaction were studied.Benzyl triethyl ammonium bromine was used as catalysis,the quantity of catalyst was 4%,the proportion of the materiel was 2∶1,the reaction temperature was 60℃,the reaction time was 6h,and the final yielding was 78.3%.
