HYDRATION OF NITRILES TO AMIDES |
摘要 |
Disclosed herein is a process for the hydration of a nitrile compound. Owing to the use of a Raney copper catalyst having an iron content of 0.7 wt. % or less based on the copper component in a suspended state, the process allows the catalyst to retain high activity and facilitates the separation of the catalyst and liquid reaction mixture by sedimentalion and/or filtration. In an example, a catalyst with 0.1 iron achieved 67% conversion of acrylonitrile to acrylamide, whereas a catalyst with 1.56% iron achieved only 40%. |
