## Abstract The kinetics of the sulphonation of benzenesulphonic acid and __m__βtoluenesulphonic acid have been measured in oleum, containing 0.7 to 43.6% of sulphur trioxide The composition of oleum solutions is expressed in the percentage by weight of sulphur trioxide, present in excess of the co

## 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 wtβ%. Similar trends are observed at 5Β° and 45Β°. The partial rate factors for __orthoβ, metaβ__
## Abstract The isomer distribution in the homogeneous monosulphonation of toluene in 77.6β98.8 wtβ % 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
