Abstract

1284139 Dinitriles IMPERIAL CHEMICAL INDUSTRIES Ltd 15 Oct 1970 [18 Nov 1969] 56403/69 Heading C2C Aliphatic dinitriles are obtained by reacting at 300‹ to 450‹ C. aliphatic dicarboxylic acids with ammonia in the vapour phase and employing a fluidized bed of silica-supported catalyst wherein the silica particles, prior to their incorporation in the catalyst, have been calcined at 450‹ to 900‹ C.
