PROCEDURE FOR THE PREPARATION OF 4-CHLORO-2,5-DIMETOXI-ANILINA. |
| abstract |
Procedure for the preparation of 4-chloro-2,5-dimethoxy-aniline by catalytic reduction with hydrogen of the nitrated compound in liquid phase at elevated temperature and pressure, characterized in that the reduction is carried out in the presence of a platinum catalyst on sulphided or sulphited carbon with the addition of catalytic amounts of buffer substances, which in aqueous solution give rise to a pH value of 8 to 10.
