【摘要】 将长链烷基季氮和非高于烷氧链引入同一个分子中,合成了兼有阳离子和非离子表面活性剂特点的低聚合表面活性剂聚氧化丙烯-α-十六烷基二甲基氯化按(PPOCA)和聚氧化丙烯-α-十四烷基二甲基氯化铵(PPOTA)。研究了其基本性质,并试用作光度分析胶束增敏试剂。更多还原

【Abstract】 Two new polymer surfactants polypropylene oxide-a-tetradecyldimethylammo-nium chloride(PPOTA)and polypropylene oxide-a-cetyldimethylammonium chloride(PPOCA)have been synthesized,which possess the characteristics of both cationic and nonionic surfactants.The properties of PPOTA and PPOCA were investigated.The synthesized surfactants can be used as sensitizing and solubilizing reagents for spectrophotometric analysis.Some examples of micellar improved spectrophotome-tric systems such as Sc(Ⅲ)-CAS,Ge(Ⅳ)-PF and Ni(I)-CAS were given.更多还原
