Preparation of 2-butanol by catalytic hydrogenation of biobased butanone over Pd/C catalyst

Preparation of 2-butanol via hydrogenation of biobased butanone catalyzed by Pd/C catalyst was studied.Effects of reaction time,reaction temperature,hydrogen pressure and catalyst dosage on the yield of 2-butanol were investigated.The results indicated that catalytic hydrogenation reaction of buta- none could be carried out over Pd/C catalyst and the main product was 2-butanol.2-Butanol yield increased with the increase of temperature under suitable temperature condition and decreased with the increasedof temperature over certain temperature.2-Butanol yields reached 53.1%,52.8% and 45.5%, respectively,under reaction condition as follows:hydrogen pressure 1 MPa,reaction time 8 h and reac- tion temperature 90 ℃,120 ℃ and 150 ℃.2-Butanol yield decreased with the increase of hydrogen pressure.Increasing catalyst dosage quickened reaction speed and shortened reaction time,but had little influence on 2-butanol yield after reaction for 8 h.
