摘　　要：以N-椰油基-1,3-丙撑二胺(CPDA)、单氰胺和醋酸为原料,合成了椰油基丙撑醋酸二胍盐(CPGA)。利用FTIR和基质辅助激光解吸电离飞行时间质谱(MALDI-TOF MS)对产物结构进行了鉴定。考察了CPGA与3种阴离子表面活性剂[脂肪醇醚羧酸钠(AEC_(9)-Na)、月桂醇聚氧乙烯(3)醚硫酸钠(AES)、十二烷基苯磺酸钠(LAS)]和两种非离子表面活性剂[脂肪醇聚氧乙烯(9)醚(AEO)、C_(12-14)烷基聚葡萄糖苷(APG_(1214))]组成的5种复配体系的稳定性、润湿性能、乳化性能、泡沫性能、去污性能和抑菌性能。结果表明,AEC_(9)-Na/CPGA复配体系外观澄清透明,润湿、乳化、泡沫、去污和抑菌性能良好,在质量浓度0.02 g/L下对金黄色葡萄球菌的抑菌率达到75.96%,对大肠杆菌的抑菌率达到91.49%,综合性能优于其他4种复配体系,在抑菌洗涤剂方面有很好的应用前景。N-coconut-1,3-propylbisguanidine acetate salt(CPGA)was synthesized by reaction of N-coconut-1,3-propyldiamine(CPDA),cyanamide and acetic acid,and then characterized by FTIR and matrix-assisted laser desorption/ionization time of flight mass spectrometry(MALDI-TOF MS).The stability,wettability,emulsification ability,foaming property,detergency performance and bacteriostatic activity of CPGA compounded with three anionic surfactants[fatty alcohol carboxylate(AEC_(9)-Na),sodium lauryl polyoxyethylene(3)ether sulfate(AES),sodium dodecyl benzene sulfonate(LAS)]and two non-ionic surfactants[fatty alcohol polyoxyethylene(9)ether(AEO),C_(12-14)alkyl polyglucoside(APG_(1214))]were further investigated.The results showed that AEC_(9)-Na/CPGA compounded system,with a clear and transparent appearance,exhibited excellent wettability,emulsification ability,foaming property,detergency performance and bacteriostatic activity,and displayed best antimicrobial efficacy against Staphylococcus aureus and Escherichia coli of 75.96%and 91.49%respectively at mass concentration of 0.02 g/L compared with those of the other four compounded systems,which suggested the great development potential of AEC_(9)-Na/CPGA compounded system as antibacterial detergents.
