Verfahren zur Herstellung von substituierten Nitro-benzoesäuren durch Oxidation der korrespondierenden Nitro-toluole, Nitro-benzylalkohole, -ester und/oder -ether

摘要

The invention relates to the production of nitro benzoic acids by oxidation of special nitro toluenes, nitro benzyl alcohols, esters and/or ethers in the presence of nitric acid at a high temperature and high pressure. The special nitro toluenes, nitro benzyl alcohols, esters and/or ethers can be oxidized in a particularly secure and economic manner in order to form benzoic acid derivatives with high yields when added to nitric acid.
