Synthesis method
Originated from the reduction of 2-chloro-5-nitrobenzoic acid. Add 2-chloro-5-nitrobenzoic acid to the reducing solution prepared from hydrochloric acid, water, and iron powder. After reduction, add sodium hydroxide to turn it into sodium salt. Filter out the iron slag and wash the filter residue with hot water. , combine the filtrate and washing liquid, use activated carbon to decolorize, add hydrochloric acid to the clear filtrate obtained after filtration, and filter to obtain the product.
Purpose
Intermediates for anti-halation dyes.
