Synthesis and Properties of a Series of Amine Oxides Containing Sulfonic Group

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.
