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 photooxidative destruction of C. I. Basic Red 46 (BR46) by UV/S2O82- process is presented. Central Composite Design (CCD) was employed to optimize the effects of operational parameters on the photooxidative destruction efficiency. The variables investigated were the initial dye and S2O82- concentrations, reaction time and distance of the solution from UV lamp. The predicted values of the photodestruction efficiency were found to be in good agreement with the experimental values (R2 = 0.9810, Adjusted R2 = 0.9643). The results of the optimization predicted by the model showed that the maximum decolorization efficiency (>98%) was achieved at the optimum conditions of the reaction time 10 min, initial dye concentration 10 mg/l, initial peroxydisulfate concentration 1.5 mmol/l and distance of UV lamp from the solution 6 cm. The figure-of-merit electrical energy per order (EEo) was employed to estimate the electrical energy consumption and related treatment costs.

Opis:
The review of literature related to the applications of statistic methods of design of experiments in chemical technology and environment protection was presented in the work. The research that consists of two stages: a stage of choosing the best variables describing an experimental object and a stage of proper experimental investigation, seems particularly interesting. An interesting example of an application of statistical strategies in environmental protection is the optimization of photoactivity of TiO2/SiO2 mixture, received by a sol-gel technique. TiO2, due to its specific feature, was applied in the photocatalytic methods of removing toxic compounds from water and air. In the experiments there were used two designs - the fractional factorial design 2^5-1 (as the elimination one) and the central composite design (as the proper one). Following the data analysis from the elimination plan two variables were eliminated, which helped to simplify the research object. Among other uncommon applications of the design of experiments: the optimization of the conditions for the extraction of natural pigments used in dyeing food, the production of fatty acid methyl esters used as diesel oil substitutes (biodiesel) and the optimization of a supercritical fluid extraction methodology for the analysis of castor oil, should be mentioned.

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.
