Abstract: Conversion of an aromatic hydrocarbon or its mixture containing sulfur containing aromatic compounds comprises lowering the content of the sulfur containing compound in the presence of hydrogen, and hydrogenating the aromatic hydrocarbon or its mixture in the presence of a ruthenium catalyst and hydrogen. An independent claim is included for a method for desulfurization of the aromatic hydrocarbon or its mixture comprising lowering the content of sulfur containing aromatic compound to = 70 ppb using desulfurization agent, where the total amount of the sulfur containing aromatic compound is = 200 ppb, and the desulfurization agent contains copper oxide (35-45 wt.%), zinc oxide (35-45 wt.%) and alumina (10-30 wt.%).

Abstract: Phosphorous chelate compounds (I) are new. Phosphorous chelate compounds (I) of formula (R1>-P(R2>)-(X)a-Y1>-(O)b-P-((O)c-Rgamma )-(O)d-Rdelta ) are new. either R1>, R2>5-7 membered heterocyclic groups that are bonded over N atom to P atom; or PR1>R2>5-7 membered heterocycle additionally contains optionally substituted N atom and a further under oxygen and optionally substituted N atoms that are bonded directly to P atom; either Rgamma , Rdelta : akyl, cycloalkyl, heterocycloalkyl, aryl or hetaryl (all substituted with 1-5 of cycloalkyl, heterocycloalkyl, aryl, hetaryl, alkoxy, cycloalkoxy, heterocycloalkoxy, aryloxy, hetaryloxy, hydroxy, thiol, polyalkylenoxide, polyalkylenimine, COOH, carboxylate, SO3H, sulfonate, NE1>E2>, NE1>E2>E3>X-, halo, NO2, acyl or CN); or PRgamma Rdelta , ORgamma Rdelta : 5-8 membered heterocycle optionally annealed with 1-3 of cycloalkyl, heterocycloalkyl, aryl or hetaryl, where the heterocycle and optionally the annealed groups are substituted with 1-4 of alkyl, cycloalkyl, heterocycloalkyl, aryl, hetaryl, hydroxy, thiol, polyalkyleneoxide, polyalkylenimine, alkoxy, halo, COOH, carboxylate, SO3H, sulfonate, NE4>E5>, NE4>E5>E6>+>X->, NO2, alkoxycarbonyl, acyl or CN; E4>, E5>, E6>H, alkyl, cycloalkyl or aryl; X : O, S, SiReRf or NRg; Re, Rf, Rg : H, alkyl, cycloalkyl, heterocycloalkyl, aryl or hetaryl; X->anion; Y1>bivalent carbon containing bridge atoms; and a-d : 0-1 (where at least one of b, c or d is 1). Independent claims are also included for: (1) catalyst comprising at least one complex with a transition metal, as ligands of (I); (2) preparation of chiral compounds comprising reacting prochiral compounds containing at least ethylenic unsaturated double bond, with a substrate in the presence of a chiral catalyst; (3) a method for hydroformylation of compounds containing at least ethylenic unsaturated double bond comprising reacting with carbon monoxide and hydrogen in the presence of hydroformylating catalyst; (4) preparation of 2-propylheptanol comprising subjecting butene or butene containing C4-hydrocarbon mixture of hydroformylation to obtain n-valeraldehyde containing hydroformylating products, optionally isolating hydroformylating products under n-valeraldehyde enriched groups, subjecting the obtained hydroformylating products and n-valeraldehyde enriched groups to aldol condensation, hydrogenating the products of aldol condensation, catalytically with hydrogen to alcohols and optionally subjecting the hydrogenation products to isolate 2-propylheptanol enriched groups; and (5) a method of hydroformylation of alpha -olefine and olefine with inner double bonds containing a composition, comprising reacting with carbon monoxide and hydrogen in the presence of hydroformylating catalyst in two-stage reaction system (where the first step comprises feeding an inlet containing olefin, carbon monoxide and hydrogen and converting partly catalytically; feeding and converting the discharge from the above step; and feeding the discharge from the second step with a stream obtained from non-reacted olefine and saturated hydrocarbons).
