松香衍生物的季铵盐阳离子表面活性剂的合成与性能测定

研究了以脱氢松香胺为原料合成N,N二甲基N苄基N脱氢松香基氯化铵和N,N,N三甲基N脱氢松香基硫酸单甲酯铵的工艺;测定了它们的物理性质和界面性能,诸如熔点、Krafft点、表面张力、乳化力、泡沫力等,表明它们具有良好的表面活性,并且与直链季铵盐类阳离子表面活性剂一样具有良好的杀菌和抑菌性能。

Synthesis and Performances of Quaternary Ammonium Cationic Surfactants with Dehydroabietyl Group

N,N dimethyl N benzyl N dehydroabietyl ammonium chloride and N,N,N trimethyl N dehyroabietyl ammonium monomethyl sulfate were synthesized from dehydroabietyl amine. Their physical and interfacial properites, such as melting point, krafft point, surface tension, emulfying ability, foaming ability were determined. The results showed they possess good surface activity and their germicidal ability are as good as alkyl quantery ammoniums cationic surfactants.
