摘要
利用在线红外光谱技术监测了聚叠氮缩水甘油醚与2,2-炔丙基丙二酸二甲酯的摩尔比为1∶1、1∶2、1∶4、1∶5的常温催化反应历程。实验结果表明:反应过程中叠氮基特征峰(2101 cm^(-1))的强度呈减弱的趋势,1285 cm^(-1)和1316 cm^(-1)处代表的N=N特征峰强度增加的趋势,说明了反应过程中存在叠氮基的消耗和三唑环的生成。
The online infrared spectroscopy technology is used to monitor the catalytic reaction process of glycidyl azide polymer(GAP)and 2,2-ethynylpropylmalonic acid dimethyl ester(DDPM)at room temperature with molar ratios of 1∶1,1∶2,1∶4 and 1∶5.The experimental results show that the characteristic peak intensity of azide group represented at 2101 cm^(-1) trends to decrease during the reaction process,and the intensity of N=N characteristic peak represented at 1285 cm^(-1) and 1316 cm^(-1) trends to increase,indicating the consumption of azide group and the generation of triazole.
