Process for the preparation of 2-hydroxybenzonitrile |
| abstract |
The present invention relates to a process for the preparation of 2-hydroxybenzonitrile by dehydration of 2-hydroxybenzamide in the gas phase, which is characterized in that the reaction is carried out heterogeneously. In particular, a silica gel impregnated with phosphoric acid, which is suitably dried before use, is used as the catalyst. The reaction is preferably carried out under reduced pressure and at a temperature between 200 and 400 ° C. |
