用在线红外研究TADFIW的碱性水解反应

Study on the Hydrolysis of TADFIW under Alkaline Condition by Online Infrared

采用在线红外光谱仪对TADFIW的碱性条件水解反应进行了研究。结果表明,TADFIW笼形化合物中六元环上的两个甲酰胺在碱性条件下很容易发生水解反应,在室温下就能够顺利进行;而TADFIW笼形化合物中五元环上的乙酰胺在碱性条件下很难发生水解,即使将温度升高到60℃,反应时间延长到3h,乙酰胺也不易发生水解反应。TADFIW在碱性条件下只能通过水解反应生成TAIW,进一步水解需要改变反应条件才能进行。

The hydrolysis of TADFIW under alkaline condition was studied using the online infrared. The results show that the hydrolysis of the two formamides on the TADFIW＇s six member ring can be easily carried out at room temperature. But the two acetamides of the TADFIW on the five-member ring almost have no reaction, even if the temperature rised to 60℃ and reaction time extended to three hours. Under the condition, through the hydrolysis of TADFIW,TAIW can be obtained, and further hydrolysis reaction can not take place, if only the reaction condition be changed.
