| titleOfInvention | Air oxidation of an aromatic aldehyde to an aromatic acid |
| abstract | A low temperature process for preparing an aromatic acid having formula (I),said process comprising reacting an aromatic aldehyde having formula (II)with a gas having an oxygen content of 1 to 100 weight percent, based on the total weight of the gas, at a temperature of about 20° C. to less than 100° C. in the presence of a supported Group VIII metal catalyst, and a solvent having a flash point greater than 95° C. and/or a melting point less than 55° C., provided that the flash point of the solvent is greater than the reaction temperature, wherein R<1 >and R<2 >are independently selected from the group consisting of hydrogen and a C1-C8 linear, branched or cyclic alkyl group. The process of the invention yields an aromatic acid in excellent yield, and (i) does not involve the use of deleterious oxidizing agents; (ii) is essentially free of by-products; and (iii) is accomplished at a temperature of less than 100° C. |
