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 9 ）、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。

Abstract: 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 9), 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.
