【Abstract】 With ultrafine amorphous NiB as catalyst and ethanol as solvent, the selective catalytic hydrogenation of 2-butylenecyclohexanone at atmospheric pressure was studied. Through the experiment, the value of the reaction order n of this selective catalytic hydrogenation of 2-butylenecyclohexanone is confirmed: n =1, and at 80℃ the reaction rate constant k of this quasi first-order reaction is equal to 3.4×10 -3 min -1 . Moreover, the effects of outer diffusion, temperature and the quantity of the catalyst on the reaction was researched. Also the activation energy of the reaction Ea was calculated : Ea=16.391 kJ/mol.更多还原
