catalyst, phosphonite binder, processes for the preparation of a mixture of monoolefinic c5-mononitriles, for the catalytic isomerization of branched aliphatic monoalkene nitriles, and for the preparation of adipodinitrile, and use of a catalyst.

摘要

A catalyst which comprises at least one complex of a metal of subgroup VIII having at least one bidentate phosphonite ligand of the formula Ior salts and mixtures thereof, a process for the preparation of mixtures of monoolefinic C5-mononitriles, a process for the catalytic isomerization of branched aliphatic monoalkenenitriles and a process for the preparation of adiponitrile.
