ニトロ基還元用触媒

Document Type and Number:

Japanese Patent JP4998889

Kind Code:

B2

Abstract:

To provide a cost-effective and highly-active catalyst for nitro group reduction.

The catalyst for nitro group reduction includes: rhodium nanoparticles obtained by reducing amide amine dendrimer-rhodium complex with chain formation of amide amine dendrimer, which is represented by formula I, wherein R1is n-valent organic molecule residue, n is 1-6, R2and R3are monovalent organic groups, x, y and z are 1-4, and m is 0-10 and shows the generation number of dendrimers, and rhodium complex; or includes rhodium/iron nanoparticles obtained by reducing amide amine dendrimer-rhodium/iron complex with chain formation of amide amine dendrimer, rhodium complex and iron complex.
