Latest Patents
Masao Nonobe holds a patent for a process titled "Process for producing aromatic carboxylic acids and methyl esters thereof." This patent discloses an improvement in the method of making an aromatic carboxylic acid or its methyl ester from an aromatic compound that has at least one methyl or formyl group bonded directly to a nuclear carbon atom of the aromatic ring. The process involves oxidizing the compound in the liquid phase with molecular oxygen or a gas containing it, using a catalyst that comprises a heavy metal compound. Notably, this process occurs in the substantial absence of an aliphatic carboxylic acid as a solvent, resulting in a reaction mixture that includes the acid. If the ester is desired, the acid is then esterified with methanol. The improvement in this process includes carrying out the oxidation in the co-presence of a lithium compound at a concentration of 0.1-10 moles per mole of heavy metal compound. The lithium compound is at least partly soluble in the reaction mixture or reacts with an acid component of the reaction mixture to form a lithium compound that is soluble in the reaction mixture.
