The scientific-technical journal

It is the scientific-technical journal in English in Ukraine discussing actual problems of chemistry and chemical technology. Compared with other chemical journals Ch&ChT is publishing materials of both theoretical and practical values in such fields as analytical, general organic, physical and inorganic chemistry; chemistry of high molecular compounds; materials science and engineering; chemical kinetics and catalysis; technology of inorganic substances; technology of organic synthesis products; chemical technology of processing of combustible minerals; processes and apparatus of chemical and food productions; biotechnology and ecology.

    Effect of barium salts on physico-chemical and catalytical properties of Fe-Te-Mo-Ox catalyst for oxidative amonolysis of isobutyl alcohol
    (Lviv Polytechnic Publishing House, 2013) Zhyznevskiy, Vyacheslav; Gumenetskiy, Volodymyr; Matskiv, Olena; Shyshchak, Olena
    The effect of barium salts (nitrate, sulphate,chloride) on the physico-chemical and catalytic properties of Fe:Te:Mo (1:0.85:1) oxide catalyst has been determined for oxidative amonolysis of isobutyl alcohol(IBA) to methacrylonitrile (MAN). The catalyst doped with BaCl2 (Ba/Mo = 0.1) was found to be the best catalyst relatively to the MAN yield. It has been shown that the promotors increase the catalyst specific surface and affect catalyst surface acidity improving the catalyst efficiency. Досліджено вплив солей барію (нітрат,сульфат, хлорид) на фізико-хімічні і каталітичні властивості Fe:Te:Мо (1:0,85:1) оксидного каталізатора реакції окиснювального амонолізу ізобутилового спирту (ІБС) в метакрилонітрил (МАН). Встановлено, що кращим за виходом МАН є каталізатор (Кт), промотований ВаСІ2 (Ва/Мо = 0,1). Показано, що промотори збільшують питому поверхню (Sп)Кт та впливають на його поверхневу кислотність, що покращує ефективність каталізатора в реакції окисню- вального амонолізу ІБС в МАН.
