Di(2-ethylhexyl)1,2-cyclohexane dicarboxylate was prepared,by using bis(2-ethylhexyl) phthalate (DEHP,industrial grade) as raw material,and with fixed-bed hydrogenation process and noble metal Ru-Pd catalyst. The influence of temperature,pressure,space velocity and volumetric ratio of hydrogen to oil on catalytic activity were investigated. Under process conditions of reaction temperature 190℃,pressure 15MPa,space velocity 0.5h-1 and volumetric ratio of hydrogen to oil 800∶1,DEHP conversion was above 99.99%and selectivity was higher than 99.7%. Moreover,the catalyst kept excellent hydrogenation activity during 8000h test running.
