Claims16
A method comprising:
- carrying out selective oxidation, in the vapor phase, of an olefinic compound with molecular oxygen to produce an epoxide, wherein the selective oxidation is carried out in the presence of an epoxidation catalyst, and wherein the epoxidation catalyst comprises:
- (i) more than 5 wt. % to 80 wt. % of a metal component and (ii) a support comprising a phyllosilicate,
- wherein the olefinic compound and the epoxidation catalyst are introduced to a reaction vessel via an input stream prior to introducing the molecular oxygen to the reaction vessel.
