CATALYST FOR SELECTIVELY HYDROGENATING AROMATIC NITRO COMPOUND, METHOD FOR PRODUCING AND REGENERATING THE CATALYST, AND METHOD FOR SELECTIVELY HYDROGENATING AROMATIC NITRO COMPOUND BY USING THE CATALYST

Title:

Document Type and Number:

Japanese Patent JP2011036748

Kind Code:

A

Abstract:

To provide a catalyst for selectively and economically hydrogenating only a nitro group even when the nitro group, a carbon-carbon double bond, a halogen atom bonded to an aromatic ring, and groups such as an aromatic ketonic carbonyl group, an aromatic carboxylate group, an aromatic amidic carbonyl group and an aromatic nitrile group are present in one and the same compound and to provide a method for selectively hydrogenating an aromatic nitro compound by using such the catalyst.

The catalyst for selectively hydrogenating the aromatic nitro compound is obtained by depositing silver and/or silver oxide on alumina as a silver component and has the deposited silver component of 0.5-3 nm average particle size. There is also provided a method for producing the catalyst. The method for selectively hydrogenating the nitro group of the aromatic nitro compound comprises a step of heating/mixing the aromatic nitro compound, the catalyst, an organic solvent and hydrogen gas.
