Abstract
1451697 1,3-Diamino-2,2-dimethylpropane RUHRCHEMIE AG 15 Nov 1974 [23 Nov 1973] 49562/74 Heading C2C 1,3-Diamino-2,2-dimethylpropane is made by contacting neopentyl glycol, ammonia and hydrogen at a temperature of 220-300‹ C. and a pressure of at least 10 atmospheres with a nickel-containing catalyst. The catalyst may also contain chromium (III) oxide and may be supported on kieselguhr. The latter may contain alumina and magnesia in addition to silica.
