Abstract

1,202,875. Preparation of aminopivalic acid. IMPERIAL CHEMICAL INDUSTRIES Ltd. 16 Feb., 1968 [14 March, 1967], No. 11954/67. Heading C2C. Aminopivalic acid is prepared by heating hydroxypivalio acid with ammonia at 175- 260‹ C. and at superatmospheric pressure in the presence of H 2 and a hydrogenation catalyst. The invention is preferably performed at 215- 230‹ C. at 150-250 atmospheres pressure using a Raney nickel catalyst, in aqueous solution.
