含酯基联接基的双子表面活性剂的合成及性能
Synthesis and properties of Gemini surfactants with ester group in the spacer
摘要
Abstract
Two quaternary ammonium type Gemini surfactants with ester group in the spacer, N, N'-didodecyl-N, N, N', N'-teramethyl-di-(2-aminoethanol)-adipate-dibromide ammonium ( DTAD) and N, N'-didodecyl-N, N, N', N'-teramethyl-di-( 2-aminoethanol) terephthalate-dibromide ammonium ( DTTD) were synthesized. The molecular structures were characterized by NMR and element analysis. The critical micelle concentration (cmc) , ionization degree of micelle ( a ) , foaming ability and foam stability were measured. The results show that DTAD has higher cmc, a than DTTD. But its foaming ability and foam stability is lower than that of DTTD. These results imply that the structure of the spacer has an important influence on the properties of Gemini surfactants.关键词
