WU Ji-min~1,ZHAO Feng-sha~2,LI Shi-han~1 (1.Nylon 66 Salt Co.Ltd,Shenma Group of China,Pingdingshan 467013,China;2.Petrochemical Research Institute of Lanzhou Petrochemical Company,PetroChina,Lanzhou 730060,China)  
This paper analyzes the causes of running off for cyclohexene hydration catalyst.Rotation rate of agitator,concentration and interface of the catalyst are major factors,and crystal regeneration and deterioration of the catalyst are also factors.Wherefore,we optimize processing conditions shown as follow:reaction temperature 120℃,pressure 0.5MPa,agitator rotation rate 45r/min,catalyst concentration 20%,catalyst interface 10%.As a result,the effect is remarkable.
