Abstract

1,129,180. Diamines. IMPERIAL CHEMICAL INDUSTRIES Ltd. 19 Sept., 1967 [23 Sept., 1966], No. 42622/66. Heading C2C. Aromatic monocyclic m -diamines are prepared by reduction of the corresponding dinitro compounds, the latter having been heated with an alkali metal phenate to lower the content of odinitro compounds. The diamines may be converted by phosgenation to diisocyanates.
