摘　　要：以异烟酸、长链脂肪醇和溴乙烷为原料,通过酰化、酯化和季铵化3步反应合成了2种异烟酸酯类季铵盐表面活性剂,用定性方法、红外光谱和核磁共振氢谱鉴定了其结构,并表征了这2种表面活性剂的表面活性.结果表明:这2种表面活性剂均有一定的降低水表面张力的能力.With isonicotinic acid, long chain aliphatic alcohol, bromethane as raw materials, two kinds of isonicotinic acid ester quaternary ammonium surfactants were prepared by acylation, esterification and quaternary ammoniation. Their structures were identified by qualitative experiments, IR and ^1H NMR. At the same time, the surface activities of the two surfactants were determined. The results show that the two kinds of surfactants both have ability of decreasing the surface tension of water.
