| Abstract: | A non-ionic surfactant lauricacid diethanolamine was synthesized using lauric acid and diethanol amine with a mol ratio 1:2.Gas chromatography-mass spectrometer(GC-MS) was used in detection of percentage of lauric acid diethanolamide in the reaction system,factors affecting the synthesis such as temperature and time were studied.The refractive index of reaction system was analyzed in the reaction. Product performance was analyzed and a comparison was made with GB/T 15046-94,which shows that the optimal synthesis conditions are 170-180℃for 2-3h at atmospheric pressure,product performance conforms to GB/T 15046-94,and refractive index of the reaction system can determine the extent of reaction. |
