METHOD OF PREPARING CATALYST FOR HYDROGENATION OF NITROBENZOTRIFLUORIDE INTO AMINOBENZOTRIFLUORIDE Russian patent published in 1997 - IPC

FIELD: catalysts for organic syntheses. SUBSTANCE: in a method where catalyst is prepared by applying 3.7-4.0 wt % of metal palladium onto carbon carrier from palladium acetate toluene solution in presence of formic acid at elevated temperature, distinguishing feature is that, as carbon carrier, carbon material with specific surface area 120-660 sq.m, transition pore volume 0.4-1.2 cu.cm/g, and rubbing strength 0.5-0.1 %/min, which is carbon black reinforced with pyrolytic carbon obtained in pyrolysis of gas hydrocarbons, and metal palladium is applied at 90-99 C for 15-60 min. EFFECT: increased activity and service life of catalyst.
