Epoxidation of rubber seed oil, an abundant non-edible vegetable oil in Yunnan Province, over bifunctional titanium silicate zeolite catalyst was investigated. In order to obtain more unsaturated fatty acids, the seperation of unsaturated fatty acid was studied firstly. Based on total preparation and characterization of Pd-bifunctional titanium silicate zeolite catalyst, the epoxidation of the model unsaturated fatty acid, oleic acid, over the catalyst was investigated to explain the mechanism of the epoxidation. After the activity test and other properties of the catalyst, the optimized catalyst and its preparation conditions were obtained by using the control method. Effects of the epoxidation conditions, such as reaction temperature, time, catalyst amount, on the conversoin, selectivity, reaction rate/kinetic rate, epoxided product structure were investigated mainly. Finally, the epoxided product of rubber seed oil with excellent properties would be obtained. Through the project, it will be valuable and helpful for the high-valuable utilization of vegetable oil and the complete or part replacement of pectroleum chemicals by non-edible vegetable oil-based chemicals.
