The effect of length of carbon chain on spumescence capability ; detersive efficiency were studied , then choose proper length carbon chain for different purpose 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。
2.
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 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。
