| Abstract: | Preparation of 1,6-Hexanediol was carried out by hydrogenation of dimethylene adipate,and effect of process parameters on the hydrogenation reactions was investigated.The condition for the hydrogenation was mild,the pressure less than 8.0 MPa,the temperature below 250℃,the mole ratio of hydrogen and dimethylene adipate is 150~300,and the dimethylene adipate space velocity below 0.5 h-1.Under these conditions,dimethylene adipate was hydrogenated into 1,6-hexanediol.The conversion of dimethylene adipate was over 99%,and selectivity of 1,6-hexanediol was more than 95%. |
