【Abstract】 the effect of doping a third element (such as Ti,Cu, etc) into the Raney nickel catalyst on the activity of the hydrogenation of butynediol was studied. Suitable conditions of the reaction when using Ti as the third element were obtained as follows: temperature: 90 ℃ ~ 110 C; hydrogen pressure: 2. 0 MPa ~3. 0 MPa; concentration of 1. 4-butynediol: 1. 5 mol/1; catalyst weight: 2. 0 kg/m3 . Under the above conditions, a high yield of bytanediol is obtained with a butynediol conversion ratio of 100%, and the selectivity of butanediol is 98. 7 %.更多还原
