Abstract

A diethyl diacetyl succinate derivative of gelatine is prepared by dissolving gelatine in water, adjusting the pH to 9.5 to 10 with aqueous sodium hydroxide, adding diethyl diacetyl succinate, maintaining the pH at 10 by occasional additions of alkali, and continuing the reaction for 6 hours at 40 DEG C. The pH is lowered to 6 to 7 by the addition of dilute sulphuric acid, and the gelatine derivative is chill set, sliced and dried. Specifications 479,239, 568,399, 649,543, 649,544, 649,547 and 649,549 are referred to.
