| 摘 要： | 用微量量热法研究了十二烷基硫酸钠(SDS)和十六烷基三甲基溴化铵(CTAB)胶束对天然肉桂油碱性水解的催化作用,并考察了反应温度、时间、pH对该水解反应的影响。实验室实验及工厂放大实验结果表明,当反应温度为368-375 K、选择碳酸钠和三乙醇胺为混合碱调节pH=10、m(肉桂醛)∶m(水)=1∶4、c(CTAB)=2.03×10-3mol/L、反应时间14 h时,苯甲醛得率最高达61%。

| Abstract: | The micellar catalysis of sodium lauryl sulfate(SDS) and cetyltrimethylammonium bromide(CTAB) on the basic hydrolysis of natural cinnamon oil was investigated by micro-calorimeter.In laboratory and factory pilot plant scale experiments,61% conversion was achieved under the conditions that reaction temperature,pH,mass ratio of oil to water,concentration of CTAB and reaction time were controlled at 368～375 K,pH=10(adjusted with sodium carbonate and triethanolamine instead of sodium hydroxide),1∶4,2.03×10-3 mol/L and 14 h respectively. |
