Abstract

The invention comprises the phthalic acid derivative of p-aminobenzenesulphonamido-p-iodobenzene of the formula <FORM:0695055/IV (b)/1> in which the phthalic acid residue may or may not be substituted, e.g. by chlorine, bromine, iodine, alkyl or aryl groups. They are prepared by reacting p-aminobenzenesulphonamido-p-iodobenzene with substituted or unsubstituted phthalic anhydride in organic acid solution. In an example, the two reagents are dissolved in glacial acetic acid and refluxed together; the phthalic acid derivative of p-aminobenzenesulphonamido - p - iodobenzene separates on cooling. Specification 603,220 is referred to.
