Abstract:
The present invention generally relates to processes for the catalytic hydrogenation of halonitroaromatics. In particular, the present invention includes processes for the catalytic hydrogenation of halonitroaromatics such as 2,5-dicloronitrobenzene to 2,5-dichloroaniline over a platinum-containing catalyst. The present invention also relates to processes for producing 3, 6-dichloro-2-methoxybenzoic acid.

Claim (Index 63):
A process for preparing a haloaminoaromatic compound, the process comprising:\n feeding hydrogen and a feed mixture comprising a halonitroaromatic compound to a hydrogenation zone; and reacting the halonitroaromatic compound with hydrogen in the presence of a hydrogenation catalyst comprising platinum on a carbon support to produce a reaction product comprising the haloaminoaromatic compound, wherein the process further comprises one or more of the following features: (1) the hydrogenation catalyst is a calcined hydrogenation catalyst; (2) the feed mixture further comprises a solvent comprising an acid; (3) the hydrogenation catalyst is an unmodified hydrogenation catalyst; (4) the feed mixture is free of dehalogenation suppressors; (5) the reaction product further comprises 2-chloroaniline and 3-chloroaniline and the mole ratio of 3-chloroaniline to 2-chloroaniline is no greater than about 6:1, no greater than about 5:1, no greater than about 4:1, no greater than about 3:1, no greater than about 2:1, or no greater than about 1:1; (6) the reaction product further comprises 2-chloroaniline and 3-chloroaniline, and the loss of selectivity from 2,5-dichloroaniline to 2-chloroaniline and 3-chloroaniline is less than about 0.4 mol. %, less than about 0.3 mol. %, or less than about 0.2 mol. %; and/or (7) the hydrogenation catalyst comprises platinum metal particles of a size up to 10 nm in their largest dimension and no more than about 50% (number basis), no more than about 25% (number basis), no more than about 20% (number basis), no more than about 15% (number basis), or no more than about 10% (number basis) of the platinum metal particles are less than 2 nm in their largest dimension.
