In the process of catalytic hydrogenation of nitrotrifluoromethylbenzene (NTB) as a model nitro compound, they investigated the pressure region of 0-5 bars. The catalyst was 5% palladium on carbon (BP-5M) with a grain size less than 60 ..mu..M. The hydrogen was 99.9% purity cylinder type. The industrial NTB was distilled under vacuum. In the experiments, they took the freshly distilled substance containing 89% meta isomer, 8% ortho isomer, and 3% para isomer. The reaction orders with respect to hydrogen were calculated by the van't Hoff method with the assumption that over a 1-min interval the reaction order with respect to hydrogen did not change, which is valid for a residual substrate concentration not less than 16.6 mole-%. The single-interval reaction orders with respect to hydrogen n/sub H/sub 2// were treated statistically.
