摘要:
从理论上分析了失水山梨醇倍半油酸酯的合成，并通过变量法试验对影响反应的温度、时间、催化剂用量等条件进行考察。用得到的失水山梨醇倍半油酸酯制备乳胶基质，测试乳胶基质的储存稳定性，以此得到优良的失水山梨醇倍半油酸酯合成条件。结果表明：采用醚化温度155 ℃、醚化时间90 min、醚化催化剂磷酸（质量分数0.5 %）、酯化温度205 ℃、酯化时间4 h、酯化催化剂NaOH（质量分数0.3 %）为合成条件时，能够得到优良的失水山梨醇倍半油酸酯。用其制备的乳胶基质在高低温循环测试中，循环次数可达20次。
Abstract:
Synthesis of sorbitan sesquioleate was theoretically analyzed, and the effect of temperature, time, catalyst amount and other reaction conditions were investigated by variable method. The stability of emulsion matrix prepared by sorbitan sesquioleate was tested. Better conditions to synthesize sorbitan sesquioleate were obtained. Optimal reaction conditions are that: the etherification temperature is 155 ℃, the etherification time is 90 min, the etherification catalyst is phosphorous acid, and the mass ratio of catalyst is 0.5%; the esterification temperature is 205 ℃, the esterification time is 4 h, the esterification catalyst is NaOH, and the mass ratio of catalyst is 0.3%. The emulsion matrix prepared by sorbitan sesquioleate with optimal reaction conditions was tested by high and low temperature cycling, and the number of cycles will be up to 20.
