【摘要】 以脂肪醇、多聚甲醛、氯乙醇和三甲胺为原料，经缩合、季铵化反应合成了１类新型的含缩醛型结构的可分解的季铵盐型阳离子表面活性剂（ＲＯＣＨ２ＯＣＨ２ＣＨ２ＮＣ（ＣＨ３）３Ｃｌ，Ｒ＝Ｃ１２Ｈ２５－，Ｃ１６Ｈ３３－）。并用ＩＲ、１ＨＮＭＲ等手段对中间体和产物的结构进行了测定。还对所合成产品的表面性质（γ，ｃｍｃ）以及其杀菌性能进行了研究，表明此类产品具有较好的表面活性和优异的杀菌性能。更多还原

【Abstract】 The acetal containing surfactants (ROCH 2OCH 2CH 2N(CH 3) 3Cl,R:-C 12 H 25 ,-C 16 H 33 )have heen prepared from alkanol , paraformaldehyde, 2 chloroethanol and trimethylamine. The structure identification was performed by using IR、 1HNMR. The properties such as the cmc, and surface tension of the aqueous solution of the surfactants were measured. They showed excellent surface active properties in water. The biocidal effect of these products on sulfate reducing bacteria(SRB) was evaluated. It is shown that they are effective biocides.更多还原
