Abstract: 1305787 Disodium m-benzene disulphonate FARBWERKE HOECHST AG 2 Feb 1970 [8 Feb 1969] 6009/70 Heading C2C Disodium m-benzene disulphonate is prepared by adding continuously to a mechanically agitated bed of disodium m-benzene disulphonate, m-benzene disulphonic acid and a substantially stoichiometrically equivalent amount of sodium hydroxide as an aqueous solution having such a strength that the heat of neutral - ization liberated by the reaction is at least partially removed by evaporation of the water in the solution, and continuously removing from the bed an amount of disodium m-benzene disulphonate substantially equal to that formed from the reactants. The heat of neutralization liberated by reaction may be partially removed either by evaporation of water added separately to the bed or by cycling the disodium mbenzene disulphonate over a heat exchanger. The m-benzene disulphonic acid may be added to the bed as a melt.
