Abstract
White crystalline solid of di-m-chloroanilinium sulfate (di-m-ClAS) wa s obtained when m-chloroaniline and cone. sulfuric acid were mixed tog ether in the ratio of 1:1 or 2:1 at room temperature. Thermal decompos ition of di-mClAS gave two isomeric chloroaminobenzenesulfonic acids ( sulfonated products) and kinetics for the same was evaluated using bot h isothermal and non-isothermal TG data. Di-m-ClAS seems to decompose by N-H bond heterolysis prior to sulfonation.
