Parameters of epoxidation of cyclohexene by tert-butyl hydroperoxide
The process of epoxidation of cyclohexene by tert-butyl hydroperoxide in the presence of Mo(CO)(6) as the catalyst has been investigated by applying statistical methods of experimental design. The influence of essential process parameters on the hydroperoxide conversion, the Selectivity of transformation to the epoxy compound with regard to the hydroperoxide consumed, the cyclohexene conversion, and the selectivity of transformation to the epoxy compound with regard to the cyclohexene consumed (response functions (Y) over cap (1) - (Y) over cap (4), respectively) have been described by regression equations in the form of polynomials of second order. The analysis of the obtained regression equations and the technological parameters allows the optimum ranges of the reaction parameters for cyclohexene epoxidation with tert-butyl hydroperoxide to be established as follows: reaction time, 2.4-5 h; temperature, 90-120 degreesC; and molar ratio of alkene to tert-butyl hydroperoxide, (2.1-4.4):1.
