| Abstract: | N-(3-long chain alkyloxy- 2 - hydroxy ) propyl-N, N, N-trimethyl ammonium bromide were synthesized from the reaction of trimethyl ammonium bromide and long chain alkyl glycidyl ether which were prepared from fatty alcohol and epichlorohydrim under a condition of phase transfer catalyst in a yield of 97%.Their structures were confirmed by IR,HNMR and elemental analyses. Surface tension and critical micelle concentration of the products were also determined in this paper. |
