Improved liquid phase process useful in the hydrocyanation of diolefinic compounds to produce nonconjugated acyclic nitriles and to the liquid phase process of isomerization of the nitriles to 3- and/or 4-monoalkene linear nitriles. The improvement involves conducting the process in the presence of zero-valent nickel and a multidentate phosphite ligand. The invention also provides a novel method of making phosphorochloridite.
L'invention concerne un processus en phase liquide améliorée utile dans l'hydrocyanation de composés dioléfiniques pour la production de nitriles acycliques non conjugués et, par ailleurs, un processus en phase liquide d'isomérisation de nitriles en 3- et/ou 4-monoalcènenitriles linéaires. L'amélioration consiste à engager le processus en présence de nickel non-valent et d'un ligand de phosphite multidenté. On décrit également un nouveau procédé de fabrication de phosphorochloridite.
