Abstract
A process for direct oxidative carbonylation of lower alkanes to acids having one greater carbon atom. The process uses a metal salt catalyst promoted by halide ions and/or a metal with oxygen as the oxidant in an aqueous medium. The process is especially effective for conversion of methane to acetic acid.
