실험 절차

The isomerization of cis-2-pentenenitrile (boiling point 127° C./1013 mbar) gives rise to the target products trans-3-pentenenitrile (boiling point 143° C./1013 mbar) and cis-3-pentenenitrile (boiling point 146° C./1013 mbar), and also small amounts of 4-pentenenitrile (boiling point 146° C./1013 mbar) and trans-2-pentenenitrile (boiling point 144° C./1013 mbar). Trans-3-pentenenitrile, cis-3-pentenenitrile and 4-pentenenitrile can be used, after distillative removal, for the hydrocyanation with hydrogen cyanide to give adiponitrile. cis- and trans-2-pentenenitrile can be recycled into the isomerization stage after distillative removal.
