| 摘 要： | 甜菜碱表面活性剂的烷基碳链的长度对其表面活性及其它性质有不同程度的影响。通过实验测定碳链长度对泡沫力、洗涤力等的影响情况,为不同使用目的选择合适长度碳链的烷基甜菜碱提供依据。结果表明:十四烷基甜菜碱的起泡力较强,十二烷基的次之;十四、十六烷基甜菜碱的洗涤力较强,十四烷基的洗涤力更强;相对碳链长的甜菜碱活性剂具有较好的加溶作用和钙皂分散力。

| Abstract: | The length of alkyl carbon chain about betaine type amphoteric surfactant affects its surface activity and other properties.The effect of length of carbon chain on spumescence capability;detersive efficiency were studied,then choose proper length carbon chain for different purpose.The result indicate that spumescence capability of myristyl lycine is strongest,lauryl lycine take second place;myristyl and cetyl lycine have better washing and decontamination capability,myristyl lycine is best for foam taking dirt;comparatively speaking,those with longer carbon chain have better action of adding dissolve and decentralization capacity of calcium soap. |
