摘要
用原位红外过程分析技术研究了异丙胺与环氧丙烷的N-烷基化反应。随反应的进行,反应物环氧丙烷826cm-1处吸光度的下降和产物位于1069cm-1峰高的逐渐增加,可清楚反映出反应的进程、反应条件的影响和反应终点的判断。结果显示该技术是研究反应机理、动力学和优化反应条件的十分有力的手段。
Fourier transform infrared spectroscopy method has been developed for in situ
monitoring the reaction of iso propylamine on propylene oxide without the need to sample the
reaction medium.The profile of the reaction and the influences of conditions can be directly
reflected in the feature absorbance changes of the reactant and product at 826 cm -1 and 1
069 cm -1 ,respectively.It is shown that the in situ infrared spectroscopy is a powerful
technique to investigate the mechanism and kinetics of the reaction and to optimize the control
conditions.
