利用电荷作用负载法，使离子型[RuCl（（R）-BINAP）（p-cymene）]＋ Cl -配合物负载于介孔γ-Al2 O3上，获得了羟基丙酮不对称加氢催化剂。考察了溶剂、温度和氢气压力等对羟基丙酮催化加氢反应的影响。结果表明，[Ru]配合物能够负载于介孔γ-Al2 O3上（Ru 质量含量为3.6%），且催化剂主要位于γ-Al2 O3表面曲度大的位置，催化剂结构在负载前后没有发生变化，具有催化反应中的热稳定性。在60℃、24 h、氢气压力8 MPa 和10 mL 甲醇作为溶剂的反应条件，58.5 mg 催化剂催化2 mL 羟基丙酮不对称加氢反应，获得了63.6%的催化转化率和42.6%的对映体选择性。

Cationic[ RuCl(( R)-BINAP)( p-cymene)]+ Cl - supported by mesoporous γ-Al2 O3 in the charge adsorption method was prepared as a catalyst for the catalytic asymmetric hydrogenation of acetol. The effect of the solvent,temperature and hydrogen pressure on the catalytic activity and the enantiomer selectivity of product was investigated. The results showed that[Ru]complex was successfully loaded on mesoporous γ-Al2 O3(Ru mass content was 3. 6% ),and the catalyst was mainly located in the big curva-ture position of γ-Al2 O3 surface,the structure of the catalyst did not change before and after loading,pres-enting the thermal stability in the catalytic reaction. Under the optimal reactions of the catalyst of 58. 5 mg,the acetol of 2 mL,the reaction temperature of 60 ℃,the hydrogen pressure of 8 MPa,the reac-tion time of 24 h and 10 mL methanol as solvent,the conversion and the enantiomer selectivity to chiral 1, 2-propanediol reached 63. 6% and 42. 6% ,respectively.
