摘要: 研究了十二烷基聚氧乙烯醚硫酸盐(AES,AESA)和十二烷基硫酸盐分别与烷基聚氧乙烯醚(AEO9)、十二烷基三甲基氯化铵(1231),椰油酰胺丙基甜菜碱(CAB)复配体系(混合表面活性剂)对乙苯的增溶能力.结果表明:阴/非复配体系的增溶能力随着非离子比例的增加而增大,阴/阳(两性)复配体系的增溶能力随着阳(两性)离子比例的增加而增大.无机盐的加入对阴/非离子混合表面活性剂的增溶能力都起到了促进作用,且增溶能力随着无机盐用量的增加而增大,增溶能力顺序为CaCl2〉MgSO4〉NaCl.Abstract: The solubilization of ethyl benzene has been studied in mixed systems of dodecyl polyoxyethylene ether sulphate(AES,AESA)and dodecyl sulfate with different ratio of mixed surfactant of dodecyl polyoxyethylene Ether(AEO9),dodecyl trimethyl ammonia chloride(1231),coconut oil amide propyl betaine(CAB)respectively.The results showed that the solubilizing ability of anionic-nonionic surfactant increased with the quantity of nonionic surfactant enlarging.Besides,the solubilizing ability of anionic-cationic(or zwitterionic) surfactant increased in proportion to the quantity of cationic(or zwitterionic)surfactant.With the inorganic salt being added,the solubilization of anionic-nonionic surfactant has been improved,showing the relation of solubilization of the inorganic salt surfactants as CaCl2MgSO4NaCl.
