Selective hydrogenation of p-chloronitrobenzene to p-chloraniline over ruthenium catalyst was found to be promoted remarkably (Selectivity: from 80.4% to 98.6%; TON: from 0.89 x 10(-2) s(-1) to 3.20 x 10(-2) s(-1)) by simply adding some water into the solvent of ethanol. The optimized volume percent of water in ethanol was 30%. The promoting effect of water was also found over various supported metal catalysts, such as Fe/SiO2, CO/SiO2, Ni/SiO2, CU/SiO2, and Ag/SiO2.
