Estimating the term…
Acetic acid is produced by oxidation of methane with an oxygen-containing gas in the presence of an acid selected from concentrated sulfuric acid and fuming sulfuric acid, a palladium-containing catalyst and a promoter, preferably a copper or iron salt. The addition of a promoter and O2 to a system that includes a palladium-containing catalyst such as PdCl2 increases the rate of acetic acid formation from methane by more than an order of magnitude as compared with prior art and, in addition, inhibits the precipitation of Pd black.
A process for the production of acetic acid from methane comprising contacting a methane-containing feed with an oxygen-containing gas in the presence of a palladium-containing catalyst, a promoter, and an acid selected from concentrated sulfuric acid and fuming sulfuric acid.
