摘　　要：合成了一类结构为R-(CH_3)N(O)-CH_2CH_2SO_3Na(R=C_8H_(17)～C_(18)H_(37))的氧化胺表面活性剂(Ⅰ),测试了各项主要物化性能。由于在结构上引入了阴离子基团,Ⅰ在溶液中随pH不同而呈现出两性/阴离子的特性。测定了Ⅰ的表面张力、临界胶束浓度、起泡力、泡沫稳定性和乳化力。A series of amine oxides was synthesized and their properties were tested. The amine oxides, R(CH_3)N(O)CH_2CH_2SO_3Na i. e. sodium N-alkyl-N-methyltaurine-N-oxides, where R is a straight chain alkyl group having from 8 to 18 carbon atoms, show amphoteric/anionic characteristics in aqueous solution depending on pH. The surface tension, the critical micelle concentration, the foaming power, the foam stability and the emulsifying power of these amine oxides were determined.
