PENTENENITRILE ISOMERIZATION |
| 摘要 |
Pentenenitrile oligomers formed in a process for isomerizing cis-2-pentenenitrile to 3-pentenenitrile are minimized in the presence of an aluminium oxide catalyst. The process comprises providing an aluminium oxide catalyst having an alkali metal and/or alkaline earth metal and/or iron content, measured in the form of alkali metal oxide and/or alkaline earth metal oxide and/or iron oxide, respectively of less than 5000 ppm by weight. |

1. A method for minimising the amount of pentenenitrile oligomers formed in a process for isomerizing cis-2-pentenenitrile to 3-pentenenitrile in the presence of an aluminium oxide catalyst; said method comprising providing an aluminium oxide catalyst having an alkali metal and/or alkaline earth metal and/or iron content, measured in the form of alkali metal oxide and/or alkaline earth metal oxide and/or iron oxide, respectively of less than 5000 ppm by weight. |
