Аннотация

Objects under study: polyatomic molecules of organic compounds -imipraminc, amitriptyline, procaine, tctracthylammonium chloride and lidocaine. Purpose: Determination of characteristic time and activation energy of the heterogen reactions of polyatomic molecule dissociation on the surface of oxidized tungsten and thermodesorption characteristics of the products of these reactions under single conditions of experiments by the isothermal methods of the non-stationary processes of surface ionization - voltage and flow modulation methods. Methods of study: non-stationary methods of surface ionization - methods of voltage and flow modulation. The results obtained and their novelty: The basic characteristics of surface ionization have been experimentally defined - the ionization coefficient for the radicals (ch ,), .v ’ - ch ,, (с,нf)2N' - ch 2 and (с2hs)2n’c2ht for polyatomic molecules of imipraminc, amitriptyline, procaine, tctracthylammonium chloride and lidocaine. The kinetic characteristics of thermodesorption have been experimentally defined for the radicals (ch ,), n’ - сн ,, (c2hs), n - ch , and (c,//s), n 'с,на being the heterogeneous reaction products of molecule dissociation - imipraminc, amitriptyline, procaine, tctracthylammonium chloride and lidocaine - by the voltage modulation method. The kinetic characteristics of the heterogeneous reaction of polyatomic molecule dissociation with decay of (C-C)^ and (с - н bonds have been defined. Practical value: A method of determining the kinetic characteristics of the heterogeneous reactions of polyatomic molecule dissociation have been proposed. Application and economic effectivity: These results have been used to perform Grant Ф-2.1.7. Field of application: physical electronics, heterogeneous catalysis, gas-analytical surface ionization industry.
