AbstractIsomeric phenolsulphonic acids and phenol-2,4-disulphonic acid were nitrated with 63% nitric acid. Chromato-polarographic method was used for separation and identification of the products. As known, nitro groups can be introduced: (1) directly into the benzene ring, (2) by substitution for sulphonic groups. It was found that both processes can proceed independently and that the existing views on the mechanism of nitration of sulphonic derivatives of the phenol require correction.
