METHOD FOR PRODUCING SUBSTITUTED NITRO BENZOIC ACIDS BY OXIDATION OF CORRESPONDING NITRO TOLUENES, NITRO BENZYL ALCOHOLS, ESTERS AND/OR ETHERS |
| 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.
