International Classification:

C07C 29/03

US Classification:

568910

Abstract:

A process for converting methane to methanol using a homogeneous catalyst has been developed. The catalyst is a metal compound having an empirical formula of MXwhere M is a metal such as Pd, Cu, Co, and Mn, X is an anion such as acetate, trifluoroacetate, sulfate, propionate, “m” is the oxidation state of M, and “x” is the anion valence of X. Generally the process involves contacting a gas stream containing methane with the homogeneous catalyst and an oxidant such as hydrogen peroxide at oxidation conditions to produce methyl trifluoroacetate. Finally, the methyl trifluoroacetate is hydrolyzed to give a methanol product stream.

US Classification:

518703, 514703

Abstract:

A process for the selective oxidation of methane to methanol using a supported transition metal catalyst has been developed. Examples of the transition metals which can be used are copper and palladium, while an example of a support is silica. Optionally, the catalyst can contain a modifier component such as cesium. Generally the process involves contacting a gas stream, comprising methane, a solvent such as trifluoroacetic acid and an oxidizing agent such as air or hydrogen peroxide with the catalyst, at oxidation conditions to produce a methyl ester, e.g. methyl trifluoroacetate. Finally, the methyl ester is hydrolyzed to yield a methanol product stream.

The process comprises forming a mixture comprising the para-xylene, a solvent, a bromine source, and a catalyst; and oxidizing the para-xylene by contacting the mixture with an oxidizing agent at oxidizing conditions to produce a solid oxidation product comprising terephthalic acid, para-toluic acid, 4-carboxybenzaldehyde. The solvent comprises a carboxylic acid having from 1 to 7 carbon atoms and an dialkyl imidazolium ionic liquid; and the catalyst comprises at least one of cobalt, titanium, manganese, chromium, copper, nickel, vanadium, iron, molybdenum, tin, cerium, and zirconium. The solid terephthalic acid composition comprises, less than about 4,000 ppm-wt 4-carboxybenzaldehyde content, and more than about 2,000 ppm-wt a para-toluic acid.
