Abstract

1500343 Aminoaryl sulphonic acids HOECHST AG 15 Aug 1975 [16 Aug 1974] 34044/75 Heading C2C An aminoaryl sulphonic acid is obtained by heating an arylamine sulphate in an "all-phase" reactor which is hermetically sealed. The arylamine sulphate is preferably in a preheated anhydrous liquid form. If the arylamine sulphate is produced continuously the process of this invention may be carried out continuously. An example is given for the production of sulphanilic acid.
