摘要
以活性中间体缩水甘油基三甲基氯化铵(GTA)和腰果酚为原料,制备了新型腰果基季铵盐表面活性剂——(3-腰果酚氧基-2-羟基)丙基-N,N,N-三甲基氯化铵,产物收率约为72%,采用高效液相色谱、红外光谱和高分辨质谱对产物进行了表征,溴酚蓝检验证实产品含有阳离子基团,泡沫性能测定显示产品具有良好的起泡及稳泡能力。同时初步测试了其表面活性,结果表明,25℃下,产品的临界胶束浓度(CMC)为6.38 mmol/L,临界胶束浓度下的表面张力(γCMC)为38.86 mN/m,新型腰果基季铵盐还具有良好的乳化作用。
A new type of cardanol based quaternary ammonium salt surfactant, i.e. 3-cardanol-oxy-2-hydroxy) propyl-N, N, N- trimethyl ammonium chloride as raw materials, was synthesized with a yield of about 72% by using cashew phenol and glycidyl trimethyl ammonium chloride(GTA) which was a kind of active intermediate. The aimed product's superficial characteristics was identified with high performance liquid chromatography, infrared spectroscopy and high resolution mass spectrometry. The cationic group was found in the product through bromophenol blue inspection. It showed good foaming capacity and foam stability through foam performance measurement. The surface activities of the product were preliminarily measured. The results showed that the critical micelle concentration (CMC) of the products was 6.38 mmol/L, surface tension at CMC (γCMC) was 38.86 mN/m. The new products shows excellent emulsifying ability.
