Title:
置換芳香族アミノ化合物の製造方法
Document Type and Number:
Japanese Patent JP4318753
Kind Code:
B2
Abstract:
The present invention relates to a hydrogenation process for the preparation of aromatic amino compounds containing directly on the aryl ring or in a side chain one or more entities that may also undergo hydrogenation, such as carbon multiple bonds, nitrile groups, imino groups or carbonyl groups. The preparation is carried out by catalytic hydrogenation of the corresponding aromatic nitro compounds in the presence of a phosphorus-modified noble metal catalyst. The invention relates also to the use of modified noble metal catalysts for the hydrogenation of aromatic nitro compounds containing carbon multiple bonds and/or substituted by nitrile, imino or carbonyl groups.
