Abstract

The rate of reaction in the sulfonation of some aromatic compounds with sulfuric acid was increased by the presence of thionyl chloride which, by reacting with the water of formation, effectively maintained the concentration of sulfuric acid above the level at which sulfonation can occur. The thionyl chloride had no measurable effect on the formation of isomers.

The sulfonstion reactions studied included those of toluene, naphthalene, bromobenzene, ortho-bromotoluene, and chlorobenzene.
