L. Brendel et al., THE SULFONATION OF AROMATIC-HYDROCARBONS .2. THE SULFONATION OF TOLUENE IN ROTATION FILM REACTOR, Hungarian journal of industrial chemistry, 22(3), 1994, pp. 199-204
The previous paper dealt with the mono- and disulphonation of benzene
using oleum and concentrated sulphuric acid. This paper discusses the
parameters of batch sulphonation reaction. The sulphonation of toluene
can be carried out with excellent yield and selectivity, moreover, ev
en at short residence times. A suitable analytical method was elaborat
ed for the evaluation of the experimental results, for the analysis of
samples taken from the reaction mixture. The experiments were carried
out in a rotation film reactor. Sulphuric acid and oleum were used in
the sulphonation of toluene.
