Opis:: An influence of the molar ratio of cis, trans, trans-1,5,9-cyclododecatriene to tert-butyl hydroperoxide, the concentration of the catalyst and the reaction time on the performance of the epoxidation process of cis, trans, trans-1,5,9-cyclodecatriene with tert-butyl hydroperoxide at the presence of molybdenum hexacarbonyl Mo(CO)6 was examined. Examinations were performed using statistical methods of the design of experiments. A mathematical model describing the influence of the parameters on conversion cis, trans, trans-1,5,9-cyclododecatriene was obtained. An analysis of the data and rests was performed and an optimal value of conversion of cis, trans, trans-1,5,9-cyclododecatriene was established.

Opis:: The process of the epoxidation of cis,trans,trans- 1,5,9-cyclododecatriene (CDT) to 1.2-epoxy-5,9-cyclododecadiene (ECDD) with the 30% aqueous hydrogen peroxide under the phase transfer conditions and with /tert-butyl hydroperoxide under the homogeneous conditions was investigated. Onium salts such as AliquatŽ 336, ArquadŽ 2HT, methyltrioctylammonium bromide and the Na2WO4/H3PO4 catalyst system are very active under the phase transfer catalysis (PTC) conditions for the selective epoxidation of cis,trans,trans-1,5,9-cyclododecatiene (PTC method). These catalytic systems were found to be as active and selective as the homogeneous phase system Mo(CO)6/TBHP (hydroperoxide method).

Opis:: The optimization studies of the epoxidation process of (1Z,5E,9E)-1,5,9-cyclododecatriene (CDT) with tert-buthyl hydroperoxide (TBHP) over the molybdenum catalyst Mo(CO)6 were performed. The reaction was examined in terms of a uniform-rotatable design. Three factors were analyzed: the reaction time, CDT:TBHP molar ratio, and the molar concentration of the catalyst (Mo(CO)6). According to the design 20 experiments were performed at the constant temperature of 70°C.
