Process for the preparation of 3-cyano-3,5,5-trimethylcyclohexanone |
| 摘要 |
A process for preparing isophorone nitrile is disclosed, whereby isophorone is reacted with hydrogen cyanide in the presence of a quaternary ammonium catalyst. Remaining catalyst is removed by thermal destruction and nitrogen sparging. Residual cyanide is removed by acidification and nitrogen sparging.
