摘　　要：采用自制的镍催化剂,以双丙酮醇为原料,选用气液固三相淤浆床反应器催化合成2-甲基-2,4-戊二醇,在反应压力1.5～2.0 MPa,反应温度100～120℃,搅拌速度480 r/min条件下,建立合成2-甲基-2,4-戊二醇的动力学模型,可以指导合成工艺放大和工业化生产。With self-made nickel as catalyst, diacetone alcohol as raw material, and gas-liquid-solid three- phase slurry bed as reactor,2-methyl-2,4-pentanediol was synthesized. The kinetics model for catalytic syn- thesis of 2-methyl-2,4-pentanediol was set up under the conditions of pressure 1. 5 - 2.0 MPa,temperature 100-120℃ and mixing speed 480 r/min,which can guide the process magnification and the commercial- ization.
