Study on the Property of Complexed Systems of a New Amphoteric Surfactant with Boron
【摘要】 以二乙醇胺与硼酸酯化合成硼酸酯 (DEAB) ,再与 1-溴十二烷烷基化合成了一类新型含硼两性表面活性剂 (RDEAB) .用二元表面活性剂溶液的热力学 ,研究了RDEAB AES、RDEAB -AEO92种水溶液的混合体系胶束中表面活性剂分子间相互作用参数 βm和胶束的组成 ,2种混合体系的 βm值分别为 :- 6 47、- 3 46 .
【Abstract】 A new type amphoteric surfactant(RDEAB) with boron was synthesized from boric acid,diethanolamine with alkyl bromide.The two mixtures of RDEAB AES,RDEAB AEO 9 were investigated by aid of the solution thermodynamics of the binary surfactants.Values of the molecular interaction parameters of the two surfactant molecules , β m in the mixed micelle and consistence of the micelle were obtained.The values of β m of two mixtures are -6.47,-3.46.
