Abstract: A method for producing benzoic acid or a methylbenzoic acid isomer is disclosed which comprises forming a dispersion comprising oxygen-containing gas bubbles dispersed in either toluene or an xylene isomer, wherein the bubbles have a mean diameter less than 1 micron. The dispersion is then subjected to reaction conditions comprising a pressure of less than about 1013 kPa and a temperature of less than about 160° C., whereby at least a portion of the toluene or xylene isomer is partially oxidized to form benzoic acid or the corresponding methylbenzoic acid isomer, respectively. In some embodiments, the methylbenzoic acid isomer is an intermediate compound, and the method further includes subjecting any unreacted xylene isomer and the intermediate compound to further oxidization, to form 1,2-benzenedicarboxylic acid, 1,3-benzenedicarboxylic acid, or 1,4-benzenedicarboxylic acid. A system of apparatus for performing the method is also disclosed.
