CATALYTIC ISOMERIZATION OF 2-METHYL-3-BUTENENITRILE TO A LINEAR PENTENENITRILE

摘要

A process for isomerizing 2-methyl-3-butenenitrile to a linear pentenenitrile such as 3-pentenenitrile with a pi -allyl nickel catalyst compound. The linear pentenenitriles can be further hydrocyanated to produce adiponitrile, an intermediate to hexamethylenediamine used in manufacture of polyamides for fibers, films and molded articles.
