CATALYZED VAPOR-PHASE ISOMERIZATION OF NONCONJUGATED 2-ALKYL-3-MONOALKENENITRILES

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.
