METHOD FOR PRODUCING 2-HALO-6-NITROBENZOIC ACIDS

摘要

The invention relates to a method for producing 2-halo-6-nitrobenzoic acids by the oxidation of 2-halo-6-nitrobenzyl alcohols and/or their esters and/or ethers with nitric acid at high temperatures. The invention also relates to a method for producing 2-halo-6-nitrobenzoic acids, starting from 2-halo-6-nitrotoluene and comprising the following stages: bromination, saponification and subsequent oxidation, whereby the oxidation is carried out according to the first method.
