Abstract

A catalyst carrying ionic liquid and metallic nanoparticles for preparing high-quality arylamine by hydrocatalyzing aromatic nitro compound is prepared through preparing immobilized ionic liquid by bonding the ionic liquid onto carrier, binding it with the active component containing transition metal or precursor, and reductive exchange. Its advantages are low reaction temp, long service life andno waste generation.

Description

Technical field:

[0001] The invention relates to an immobilized ionic liquid-nano metal particle catalyst and its preparation method and its application in the hydrogenation of aromatic nitro compounds to synthesize aromatic amines under mild conditions, more specifically, a A liquid stable nanometer metal catalyst, a preparation method thereof, and a method for preparing high-quality aromatic amines by using the catalyst to catalyze the hydrogenation of aromatic nitro compounds. Background technique:

[0002] Aromatic amines are an important class of organic raw materials and intermediates, widely used in chemical, pharmaceutical, dye, pesticide and other fields, and can be used to prepare agricultural chemicals, dyes, medicine and polyurethane polymer materials. Catalytic hydrogenation is a simple, clean and economical method for the reduction of nitro compounds to the corresponding aromatic amines, and is currently the main method in industrial production. Among the worl...
