Abstract
The kinetics of phenylhydroxylamine hydrogenation reaction on skeletal nickel catalyst in 2-propanole aqueous solutions was studied. It was shown that the value of phenylhydroxylamine and aniline adsorption increases with an increase in the molar fraction of water in the binary solvent 2-propanole-water. It was found experimentally that the hydrogenation reaction is of the first order with phenylhydroxilamine and of the zero order with hydrogen. It is noted that the amount of hydrogen absorbed in the reduction of phenylxydroxylamine in the initial phase of the reaction is considerably lower than the stehiometry of the reaction would indicate. The reasons for the effect of solvent on the features of phenylhydroxilamine hydrogenation are discussed.
