Document Type and Number:
WIPO Patent Application WO/2022/224741
Kind Code:
A1
Abstract:
[Problem] In hydrogenating an aromatic halonitro compound, to improve the yield of a halogenated aromatic amine that is the target product without requiring a dehalogenation inhibitor, while suppressing the formation of a nitroso compound. [Solution] A hydrogenation catalyst to be used for hydrogenating an aromatic halonitro compound, said hydrogenation catalyst comprising a carrier containing at least one of silica, titania and alumina and at least one metal that is supported on the carrier and selected from the group 10 elements of the periodic table.
