Abstract
The protodesulphonation of 7-hydroxy-2-naphthalenesulphonic acid (F-acid) was investigated in dilute aqueous sulphuric acid at temperatures of 522–553 K. The hydrolysis of the sulpho group is irreversible and F-acid can be completely converted into 2-naphthol in a short time. The hydrolysis rate depends strongly on the temperature and on the sulphuric acid concentration; a rate equation was derived from the experimental data.
