Selective cis/trans isomerization of 2-pentenenitrile in a solution of pentenenitrile isomers |
| abstract |
Cis- and trans-2-pentenenitriles in a mixture of pentenenitriles are brought closer to their equilibrium ratio by contacting the mixture with a Lewis acid/Lewis base catalyst composition. By this process trans-2-pentenenitrile can be removed from a mixture containing mainly 3-pentenenitrile by isomerizing the trans-2pentenenitrile to cis-2-pentenenitrile and removing the more volatile cis isomer by fractional distillation. There is substantially no isomerization of 3-pentenenitrile to cis- or trans-2-pentenenitrile. |
