Abstract
This disclosure describes a new route to acrylate esters via direct catalytic partial oxidation of allyl ether using heterogeneous manganese oxide catalysts. The method involves forming allyl acrylate by contacting allyl ether, where the allyl ether is in solution with a solvent, with one or more oxidants in the presence of a mesoporous manganese oxide (MnOx) catalyst. Oxygen or peroxide can be used as the oxidant. The yield of and selectivity for acrylate ester can be very high, and process efficiency is improved over current processes.
