PP-I-35COMPARISON CATALYTIC ACTIVITY OF SUPPORTED AND HOMOGENEOUSCATALYSTS IN REACTION OF OXIDATION α-PINENE AND2,3,6-TRIMETHYLPHENOLEMenshikov S.Yu., Sennikov M.Yu. 1 , Ostroushko A.A. 1 , Кovalyova E.G., Petrov L.A.,Saloutin V.I.Institute of Organic Synthesis Ur.Br. of RAS, Ural State University, Ekaterinburg, RussiaE-mail: kox@ios.uran.ruIt was investigated catalytic activity of homogeneous complexes Сu (II), Co (II) and Mn(III), and also the heterogeneous species containing in the structure some transition metals(Cu, Mo, Co) in reaction of oxidation an alpha - pinene and 2,3,6-trimethylphenole.For the investigated catalysts values of specific rate of oxidation of substrates in areactionary mixture are determined.The oxidation of α-pinene by O 2 and H 2 O 2 continue to draw attention of researchers aswhen non-polluting oxidisers are used for oxidation [1, 2]. In our work catalytic activity wasinvestigated of supported on polymeric carriers chelates Co, Сu, and also of a polymeric-saltcomposition of polyvinyl alcohol with ammonium heptamolybdate, in comparison withhomogeneous complexes Сu (II), Co (II) and Mn (III) including those capable of reversibleattach of O 2 [3]. Catalytic experiments were conducted in organic or aqueous solutions in astatic system containing a glass reactor with two divisions positioned inside a thermostat. Twodivisions in the reactor allow preventing mixing of individual components of reaction solutionup to finishing all preparatory operations. All initial kinetics with a reaction order ≠ 0 wastreated as pseudo-first-order reactions. The initial rates of O 2 conversion were calculated bythe method presented in previous article [4]. Kinetic studies have shown, that catalyticproperties of homogeneous 2-methylpiridinic complexes Co (II) provide the highest initialrate of oxidation of a α-pinene from all investigated homogeneous complexes. They can bearranged depending on the activity in the following order: (2-MeC 5 H 4 N) 2 CuCl 2 < Co(acac) 2
