| 摘 要： | 在高压条件下，以叔胺和碳酸二甲酯为原料，合成了新型季铵盐表面活性剂-C16/C18烷基酰胺丙基三甲基碳酸甲酯铵，通过质谱和红外光谱对其进行表征。利用得到的碳酸甲酯铵分别与相应的酸进行反离子转化反应，得到系列具有新型反离子X- (X=HCOO, CH3COO, CH3CH(OH)COO)的季铵盐。初步研究了此系列化合物的表面张力，结果表明反离子对季铵盐的表面性能有影响。

| Abstract: | C16/C18 alkyl amidoproyl trimethyl ammonium mono-methyl carbonate was synthesized via a high pressure process with tertiary amines and dimethyl carbonate, the chemical structure of which was confirmed using mass spectral fragmentation and FTIR spectroscopic analysis. In addition, several quaternary ammonium salts with new counterions X- (X= HCOO, CH3COO, CH3CH(OH)COO) were also synthesized by ion exchange reaction of methyl carbonate quaternary ammoniums with corresponding acids. The surface activities of these quaternary ammonium salts were studied. The results show that counterion chain length has effect on the surface tension. |
