A process for the preparation of non conjugated linear acyclic 3-and/or 4-monoalkenenitriles by vapor phase isomerization of an acyclic aliphatic nonconjugated 2-alkyl-3-monoalkenentrile

摘要

A vapor-phase process for the catalytic isomerization of 2-alkyl-3-monoalkenenitriles to 3- and/or 4-monoalkene nitriles, wherein a supported composition of zero-valent nickel and multidentate phosphite ligand is used as the catalyst. Preferably, specially treated or selected catalyst supports are used.
