Description

The object of research : The reactions of indene, phenol and thiophene (products of coke production) under conditions of catalysis by phosphoric acid and in a mixture of NaNO2-H2O2; strongly acidic reagent partition systems in chromatomasspectrometry analysis of indene-coumarone fraction (ICF). Purposes of research: Finding of conditions of the catalytic alkylation of phenol by indene; determination of optimal conditions of oxidation of thiophene in a mixture of NaNO2 - H2O2; finding for new opportunities ICF pre'column processing in its gas chromatography analysis.Recearch methods: original kinetic methods, gas-liquid chromatography, pH-metry. Conditions of effective phosphoric acid catalysis of alkylation of phenol by indene were determinated. The simplicity of the process, the importance of products (ortho- and paraindanilfenols) make this method perspective for the introduction. The conditions and ways of oxidation of thiophene in a mixture of NaNO2-H2O2, generating peroxynitrous acid HO-ONO, were studied. Kinetics and substrate selectivity of liquid phase and gas phase routes of reactions as thiophene and as previously studied alkanes, agrees with that active particles in both routes of these transformations are OH radicals formed during of homolysis of HO-ONO bond. The proposed system can be used for the oxidative desulfurization of hydrocarbon raw materials. ICF partition reaction pre-treatment allows to develop analysis techniques of a coke-chemical fractions for the conditions of works laboratories.
