Item Catalytic Cyclohexane Oxidation In The Presence Of Alcohols Of Different Nature(Видавництво Львівської політехніки, 2013) Suprun, Oleksandr; Reutskyy, Viktor; Ivashchuk, Oleksandr; Mudryy, SergiyQuantitative and qualitative influence of binary catalytic systems [cobalt naphthenate – alcohol] in liquidphase homogeneous-catalytic oxidation of cyclohexane was considered.Item Effect of solvents on reactions of oxidation with aliphatic peroxyacids(Видавництво Львівської політехніки, 2013) Natalia Matsyuk, Mariya Matsyuk; Volodymur DutkaOrganic solvents effect on the reactions of oxidation involving aliphatic peroxyacids was studied. It was found the kinetic and activation parameters of the oxidation of aniline. It is shown that the reaction medium has a significant effect on the rate of the process. The epoxidation reaction of α-pinene and Δ3-karen by peroxydecanoic acid was studied. It was obtain the equation of correlation that connecting speed reaction with the basic physicochemical properties of solvents.Item The influence of oxidation and heat treatment on the bromination of activated carbon surface(Видавництво Львівської політехніки, 2013) Klypa, Kristina; Veselovskyi, Volodymyr; Zaderko, Oleksandr; Diyuk, Vitaliy; Ischenko, OlenaAbstract – The bromination of activated carbon as a method of the surface functionalization of carbon materials was investigated. It was found that the bromination with an aqueous solution of Br2•KBr is accompanied by the oxidation of the surface. The influence of the surface oxidation and heat treatment on the bromination of activated carbon samples was examined. It was found that the heat treatment can partially or fully recover the reactivity of the surface of the oxidized carbon materials by removing the oxygen-containing functional groups.Item Effect of nitrogen- and oxygen-containing additives on the efficiency of the catalytic oxidation of cyclohexane(Видавництво Львівської політехніки, 2013) Mudryy, Sergiy; Reutskyy, Victor; Ivashchuk, Oleksandr; Suprun, OleksandrThe research of influence of oxygen- and nitrogen- containing organic catalytic additives to the general parameters of the process of cyclohexane oxidation have been conducted. Investigated additives can change the composition of the products of oxidation and the ratio between them.The most effective additives was bis-2-cyanethyl ether and polyethylene glycol with a molecular weight of 400 g/mole. This effect is explained by research results of IR- spectra. With the use of modern computer technology built spatial model of intermediate active complex consisting of organic additives and cobalt naphthenate.
