摘要:
红外光谱采用漫反射模式(diffuse reflectance infrared fourier transform spectroscopy, DRIFTS)可直接对固体表面化学基团进行定性和定量分析. 通过在DRIFTS上安装热台,实时监测不同反应温度时异氰酸酯基的含量及其变化,可实现在固体表面原位表征端羟基聚丁二烯(hydroxyl-terminated polybutadiene, HTPB)与甲苯二异氰酸酯(toluene diisocyanate, TDI)的聚合反应. 通过不同温度时异氰酸酯基(—NCO)含量随反应时间的变化计算了活化能. 实验结果表明,原位漫反射红外光谱可准确监测HTPB与TDI的聚合反应,且实时快捷.
Abstract:
A diffuse reflectance infrared fourier transform spectroscopy (DRIFTS) was loaded down with extra heating device in order to determine the concentration of isocyanate (NCO) on the solid surface via the band area at 2 270 cm-1 in situ. The real-time progress of the curing reaction between toluene diisocyanate (TDI) and hydroxyl-terminated polybutadiene (HTPB) can also be monitored directly with only tiny amounts of the reactant mixtures at elevated temperatures. The corresponding reaction activation energy was obtained by fitting the data of NCO concentration at different temperatures. The experiment results indicate that DRIFTS in situ can determine accurately and rapidly the curing reaction of HTPB and TDI in real time.
