## Abstract The isomer distribution in the homogeneous monosulphonation of toluene in 77.6‐98.8 wt‐ % aqueous sulphuric acid has been determined at various temperatures between 5 and 65Β°. Sulphone formation and disulphonation are negligible. The isomer distribution is independent of toluene convers

## Abstract The ratio of the overall rate constants for the sulphonation of toluene and benzene in aqueous sulphuric acid at 25Β° decreases from 110 to 25 on varying the acid concentration from 78 to 92 wt‐%. Similar trends are observed at 5Β° and 45Β°. The partial rate factors for __ortho‐, meta‐__

## Abstract Rate measurements have been made on the homogeneous sulphonation of toluene in aqueous sulphuric acid varying from 70.0 to 95.9 wt‐% at 5.0Β°, 25.0Β° and 45.0Β°. In addition, rate constants have been determined for the homogeneous sulphonation of ethylbenzene and isopropylbenzene at 25.0Β°
