Abstract
1340027 Aromatic diamines E I DU PONT DE NEMOURS & CO 19 Nov 1971 [18 Dec 1970] 53875/71 Heading C2C [Also in Division B1] Aromatic diamines are prepared by reacting a mixture of an aromatic hydrocarbon or an alkyl substituted aromatic hydrocarbon, and a monoamino derivative of such an aromatic hydrocarbon with ammonia in the presence of a nickel/nickel oxide catalyst composition at a temperature of from 250‹ to 475‹ C. and a pressure of from 100 to 800 atmospheres, the mole ratio of the monoamino derivative to the aromatic hydrocarbon being from 1 : 2 to 2 : 1, thereby converting the aromatic hydrocarbon to its monoamino derivative and the monoamino derivative to the corresponding diamine. The nickel/nickel oxide catalyst may additionally comprise at least one oxide or carbonate of Zr, Sr, Ba, Ca, Mg, Zn, Fe, Ti, Al, Si, Ce, Th, U or an alkali metal.
