Abstract
A process for the complete or partial oxygenation of hydrocarbons comprises contacting a C1-C8 hydrocarbon, molecular oxygen, and hydrogen peroxide, in the presence of water and a heterogeneous catalyst, under conditions suitable to convert the C1-C8 hydrocarbon to at least one corresponding C1-C8 oxygenate product, wherein the heterogeneous catalyst provides confinement and contains both Brønsted-Lowry acid centers and Lewis acid centers. The reaction may be carried out at a temperature ranging from 2° C. to 90° C. The use of molecular oxygen increases the economic attractiveness of the process while also improving yield.
Claims8
A process for the complete or partial oxygenation of hydrocarbons, comprising contacting a C1-C3 alkane, molecular oxygen, and hydrogen peroxide, in the presence of water and a heterogeneous catalyst, under conditions suitable to convert the C1-C3 alkane to at least one corresponding C1-C3 oxygenate product, wherein the heterogeneous catalyst provides confinement of the C1-C3 alkane molecule, contains both Brønsted-Lowry acid centers and Lewis acid centers, and is selected from iron modified heterogeneous catalysts;
- and the conditions include a total system pressure of at least 0.81 megapascals.
