| titleOfInvention | Epichlorohydrin production process by direct epoxidation of chloropropene, modified heteropolymetalate-supported catalyst and production method |
| abstract | The present invention relates to a process for producing epichlorohydrin by direct epoxidation of chloropropene, a modified heteropolymetalate-supporting catalyst and a production method, and more specifically, chloropropene is peroxidized in the presence of a modified heteropolymetalate-supporting catalyst. It relates to a process pathway for producing epichlorohydrin by direct epoxidation using hydrogen water as an oxygen source. The main advantages of the process are: (1) The ratio of chloropropene to hydrogen peroxide solution is low, and the amount of chloropropene used is small. (2) Reaction and separation processes are combined, equipment is saved, and the process is simple. (3) Avoid side reactions where epichlorohydrin hydrolyzes with water under acidic conditions, High yield and selectivity of epichlorohydrin. |
