Process for Preparing Epichlorhydrin from Ethane

Process for Preparing Epichlorhydrin from Ethane

A process for preparing epichlorohydrin comprises (1) converting ethane to 1,2-dichloroethylene (cis/trans mixture) in the presence of a catalyst; (2) producing 2,3dichloropropanal by (a) hydroformylating the 1,2-dichloroethylene in the presence of a catalyst, carbon monoxide, and hydrogen, (b) addi...

Zusammenfassung:A process for preparing epichlorohydrin comprises (1) converting ethane to 1,2-dichloroethylene (cis/trans mixture) in the presence of a catalyst; (2) producing 2,3dichloropropanal by (a) hydroformylating the 1,2-dichloroethylene in the presence of a catalyst, carbon monoxide, and hydrogen, (b) adding MeOH to the 1,2dichloroethylene, or (c) subjecting the 1,2-dichloroethylene to direct reductive hydroformylation in the presence of a reductive hydroformylation catalyst; and (3) epoxidizing the 2,3-DCH with a base to produce epichlorohydrin.
