Preparation process for indoles |
| abstract |
Disclosed herein is to react an aniline and an ethylene glycol at a superatmospheric pressure in preparing an indole by subjecting the aniline and ethylene glycol to a gas-phase catalytic reaction in the presence of a catalyst, thereby improving the selectivity of the reaction and the service life of the catalyst. |
