    Molecular modeling of the isoquinoline and hinaldyne reaction of oxidation by peroxyacids
    (Lviv Polytechnic Publishing House, 2015) Zvir, Ivanna; Dutka, Volodymur; Matsyuk, Natalia; Matsyuk, Mariya; Zastavska, Gаlyna; Kovalskyi, Yaroslav; Ivan Franko National University of Lviv
    Optimal-geometric structures of molecules was calculated with semi-empirical quantum-chemical methods. The heat of formation (ΔHf), the heat of reaction (ΔHex) was found. Numerical values of ΔHf was calculated theoretically is satisfactorily coincide with the data obtained experimentally.

    Single stage acrylic acid obtaining based on methanol and acetic acid
    (Lviv Polytechnic Publishing House, 2015) Nebesnyi, Roman; Shpyrka, Iryna; Shatan, Anastasiia-Bohdana; Lukiyanchuk, Andriy; Ivasiv, Volodymyr; Nebesna, Yuliia; Lapychak, Nazariy; Lviv Polytechnic National University
    The new complex oxide acid type catalysts were developed and their performance in the process of aldol condensation of acetic acid with formaldehyde to acrylic acid was studied. The optimum conditions of the process were determined. It was established that these catalysts are effective in the process of methanol to formaldehyde oxidation, and also in the process of single stage acrylic acid obtaining from acetic acid and methanol in the presence of air.

    Influence of surface-active additieves on processes of alkylaromatic catalytic oxidation
    (Lviv Polytechnic Publishing House, 2015) Reutskyy, Volodymyr; Hrynchuk, Yurii; Lviv Polytechnic National University
    The process of ethylbenzene oxidation in the presence of catalytic systems, that consists fromsalt of variable valence metal and organic additives, was explored. Suggestion about the influence mechanism of additives on the ethylbenzene oxidation process were made.
