반응 단계
439.7 g of powdered anilinium hydrogensulphate were heated for 7 hours at 200° C. in a closed autoclave. After cooling, the autoclave was opened and the solid was dissolved in 1N NaOH (pH 7.2), deposited aniline was separated off, residual aniline was removed by extraction with methylene chloride (2×100 ml) and the aqueous phase was evaporated to dryness. The analysis of the powdery product showed a yield of p-sulphanilic acid Na salt of 68.5%, based on employed aniline. 0.7% of aniline-2-sulphonic acid and 0.02% of aniline-2,4-disulphonic acid were formed.
