Abstract
The production of acrylates and methacrylates, made by the oxidative esterification of propylene or isobutylene wherein gaseous reactants are contacted with one or more catalysts and ethylene or an alcohol can be advantageously conducted in a single fluid bed reactor to obtain the desired ester.
Claims11
A process for the oxidative esterification of unsaturated olefins selected from the group consisting of propylene and isobutylene, to produce acrylates and methacrylates, respectfully, comprising:
- a. passing a gaseous stream comprising the olefin, molecular oxygen and ethylene or an alcohol to a single fluid bed reactor, said reactor containing one or more oxidation catalysts effective for the oxidation of the olefin to its corresponding aldehyde and acid, and operated at a temperature between 200.degree. to 600.degree. C., and
- b. collecting the acrylates or methacrylates in the reactor effluent.
