Abstract

A benzenesulphonyl derivative of gelatine is prepared by adjusting the pH of an aqueous gelatin solution to 9.5 with aqueous sodium hydroxide, heating to 110 DEG F., adding benzenesulphonyl chloride while maintaining the pH at 9.5 and the temperature at 110 DEG F. and for 45 minutes after the addition, and reducing the pH to 6 to set the mass. Phenyl and p-tolyl isocyanate, maleic anhydride, benzoyl and furoyl derivatives may be similarly prepared. A benzoyl derivative may be prepared from glue. Phthalyl and m-carboxybenzenesulphonyl derivatives of gelatin may be similarly prepared using solutions of phthalic anhydride and m-carboxybenzenesulphonyl chloride respectively in dry acetone. Specifications 649,543, 649,544, 649,545, 649,547 and 649,549 are referred to.
