    The initial stages of cyclooctene oxidation by molecular oxygen in the presence of tert-butyl hydroperoxide
    (Publishing House of Lviv Polytechnic National University, 2007) Trach, Yuriy; Bulgakova, Lidiya; Makota, Oksana
    The initial stages of liquid-phase oxidation of cyclooctene by molecular oxygen in the presence of tert­butyl hydroperoxide were investigated. It was shown that radical formation is the result of bimolecular decomposition of hydroperoxide. The influence of azodiizobutyronitrile on this process was studied. The kinetic parameters of the process were calculated. Досліджено початкові стадії рідиннофазного окиснення циклооктену молекулярним киснем у присутності гідропероксиду третбутилу. Показано, що зародження радикалів відбувається внаслідок бімолекулярного розпаду гідропероксиду. Вивчено вплив на цей процес азодиізобутиронітрилу. Розраховано кінетичні параметри процесу.

    1,3-butadiene and methacrylonitrile obtaining using oxidative conversion of C4 olefins over Fe-Te-Mo-Ox catalyst promoted with BaCl2
    (Publishing House of Lviv Polytechnic National University, 2007) Gumenetskiy, Volodymyr; Maikova, Svitlana; Zhyznevskiy, Vyacheslav
    The effect of BaClP promotor on the catalytic properties of Fe-Te-Mo-Ox catalyst of joint oxidative dehydration and oxidative amonolysis of Cp olefins has been examined. The optimal composition of promoted catalyst has been established taking into consideration methacrylonitrile and butadiene yields. The process kinetics has been investigated. Досліджено вплив промотора ВаСl2 на каталітичні властивості FeTe-Mo-Оx каталізатора сумісного процесу окиснювального дегідрування та окиснювального амонолізу олефінів фракції С4. Встановлено за виходом метакрилонітрилу і бутадієну оптимальний склад промотованого каталізатора, на якому досліджено кінетику процесу.
