## Abstract The isomer distribution in the homogeneous monosulphonation of toluene in 77.6โ98.8 wtโ % aqueous sulphuric acid has been determined at various temperatures between 5 and 65ยฐ. Sulphone formation and disulphonation are negligible. The isomer distribution is independent of toluene convers
From the electrochemical fluorination of the chloride and the fluoride of benzenesulphonic acid, in addition to the main product C,F,,SO,F, the side products C,F,(CF,)SO,F, a structural isomer of the main product and C,;F,,CI-SO,F are also obtained. The NMR analysis of these products was performed.
## Abstract Rate measurements have been made on the homogeneous sulphonation of toluene in aqueous sulphuric acid varying from 70.0 to 95.9 wtโ% at 5.0ยฐ, 25.0ยฐ and 45.0ยฐ. In addition, rate constants have been determined for the homogeneous sulphonation of ethylbenzene and isopropylbenzene at 25.0ยฐ
