Abstract
a -Alkyl-a , o -dinitrile alkanes are obtained by reacting a dinitrile of the formula NC-(CH2)n-C(CN):CR1R2 where n is an integer from 1 to 12 and R1 and R2 are hydrogen or C1- 12 alkyl, with hydrogen at 10 DEG to 100 DEG C. and at a pressure of 1 to 135 atm. in the presence of a Group VIII hydrogenation catalyst. The catalyst may be employed on a support and an inert diluent, e.g. a C1- 12 alkanol, may be present. In Examples I and II, 2-methyl glutaronitrile is obtained by hydrogenating 2-methylene glutaronitrile in the presence of a palladium or carbon catalyst at 22 DEG C./100 atm. and 40 DEG C./68 atm. respectively. In comparative Example III, 3-methyl piperidine, 2-methyl,1,5-diamino pentane, 2-methyl-5-aminovaleronitrile and 1,3-dicyanobutane are obtained by hydrogenating 2-methylene glutaronitrile in the presence of a supported nickel catalyst at 100 DEG C. and 170 atm.
