Abstract

Abstract: Using home-made tris(acetylacetonato)ruthenium(Ⅲ), Ru(acac)3, as catalyst, the hydrogenation of nitrobenzene to aniline via a hydrogen transfer process using sodium formate as hydrogen donor was investigated. The effects of reaction conditions such as temperature, time, dosage of catalyst and categories of hydrogen donor were investigated. The optimized reaction conditions are: the reaction temperature is 80 ℃, the reaction time is 4 h and the molar ratio of sodium formate to nitrobenzene is 2∶1. Under optimized conditions, the conversion of nitrobenzene is nearly 100% with 96.65% yield of aniline. This result shows that Ru(acac)3 exhibits good catalytic activities in the hydrogenation of nitrobenzene.

Key words: tris(acetylacetonato)ruthenium（Ⅲ）, catalytic transfer hydrogention, nitrobenzene, aniline
