摘　　要：以三种脂肪酸酰胺基丙基叔胺和2-羟基-3-氯丙基磷酸酯钠为原料,通过不同的实验方法,合成了三种脂肪酰胺丙基磷酸酯甜菜碱(简称Cn-APA,n=12,14或16),结果表明加压反应的产率高达95%,相比于常压反应,加压反应能极大地缩短反应时间,提高反应产率,产物结构通过红外图谱和质谱表征。研究了三种产物的表面活性、去污性能、泡沫性能、乳化性能以及抗静电性能。结果表明C12-APA,C14-APA和C16-APA的cmc分别为5.1×10^-4,3.4×10^-4和8.2×10^-5 mol/L,产物拥有良好的发泡稳泡性、乳化性能,对皮脂的去污力良好,且具有优良的抗静电性能。Three fatty amide propyl phosphobetaines(abbreviated as Cn-APA,where n=12,14 or 16)were synthesized with three fatty acid amidopropyl tertiary amines and sodium 2-hydroxy-3-chloropropyl phosphate by different experimental methods.The results show that the yield of the pressurized reaction is as high as 95%.Compared with the atmospheric pressure reaction,the pressurized reaction can greatly shorten the reaction time and increase the reaction yield.The structure of the products was characterized by infrared spectroscopy and mass spectroscopy.The surface activity,detergency performance,foam properties,emulsifying properties and antistatic performance of the three products were investigated.The results show that the cmc of C12-APA,C14-APA and C16-APA are 5.1×10^-4,3.4×10^-4 and 8.2×10^-5 mol/L,respectively,and all products possess good foam stability,good emulsifying properties,good detergency to sebum,and excellent antistatic properties.
