“…In the presence of homogeneous molybdenum catalyst the effect of solvent was also investigated, and it was thought that the formation of molybdenum complexes with solvent can influence the performance of catalyst dramatically [23]. Herein, protic and aprotic solvents are chosen to investigate their effects on the performance of MoO 3 /SiO 2 catalyst, and the results are shown in Table 1.…”

This work presents the studies on the epoxidation of 1,5,9-cyclododecatriene (CDT) with hydrogen peroxide as the oxidizing agent, under conditions of the phase transfer catalysis (PTC), and with the following catalytic system: H2WO4/H3PO4/[CH3(CH2)7]3CH3N+HSO4− (compounds were mixed at the ratio of 2:1:1). The influence of the following parameters on the course of this process was investigated: catalyst content, molar ratio of H2O2:CDT, temperature and type of solvent. The highest yield of 1,2-epoxy-5,9-cyclododecadiene (ECDD) (54.9 mol%), at the conversion of CDT reached 72.3 mol%, was obtained at the temperature of 50 °C, for the catalyst content of 0.45 mol% (in relation to the introduced CDT), for the molar ratio of H2O2:CDT 1.5:1, with toluene as the solvent and after the reaction time of 30 min. Considering the he obtained results and numerous applications of ECDD, further research should be developed to provide a more efficient and environmentally friendly way of obtaining this compound.

“…Cyclododecanone is formed during the isomerization of epoxycyclododecane catalyzed by MgI 2 . Small amounts of cyclododecanone and cyclododecanole are obtained as a result of ECDD hydrogenation in the presence of such catalysts as Ni Raney, Ni/Al 2 O 3 , and Ni/Cr 2 O 3 . By conventional methods cyclododecanone is converted to ω-dodecanolactame and decanedicarboxylic acid, which are semiproducts in the production of polyester and polyamide resins and fibres .…”

The influence of the technological parameters on the epoxidation of (Z,E,E)-1,5,9-cyclododecatriene (CDT) with 30% hydrogen peroxide to (E)-1,2-epoxy-(Z,E)-5,9-cyclododecadiene (ECDD) was studied under the conditions of phase transfer catalysis (PTC), in the presence of H3PW12O40/Aliquat 336 catalytic system. The parameters considered included stirring speed, the molar ratios of CDT:H2O2 and H2O2:H3PW12O40, temperature, and the nature and concentration of solvent. The variation ranges of these parameters ensuring a high CDT conversion and high selectivity of transformation to ECDD were established. The CDT conversion was 51.4–55.6% and the selectivity of transformation to ECDD was 79.8–95.1%.
