| titleOfInvention | METHOD FOR OXIDATION OF ALKYLAROMATIC HYDROCARBONS CATALIZED BY N-HYDROXYDIVERATIVE |
| abstract | 1. A method of oxidation of alkyl aromatic products to hydroperoxides and subsequent possible production of phenol and carbonyl compound CC, including: a) selective aerobic oxidation of alkyl aromatic hydrocarbon C-C to the corresponding hydroperoxide catalyzed by N-hydroxy derivatives, in the presence of at least one polar solvent and, if necessary , water (co-solvent); b) recovery of the catalyst from the oxidized mixture by possible removal of the solvent by distillation and / or cooling of the oxidized mixture, subsequent precipitation and filtration of the catalyst based on N-hydroxy derivatives, and adsorption; c) possible decomposition of the alkylaromatic hydrocarbon hydroperoxide into phenol and carbonyl compound using homogeneous and heterogeneous acid catalysts; characterized in that the oxidized mixture, possibly concentrated, cooled and filtered, is treated with non-basic adsorbing solids to substantially completely recover the catalysis torus. 2. The method of claim 1, wherein the catalyst is selected from N-hydroxyphthalimide and N-hydroxysaccharin. The process according to claim 1, wherein the oxidation of the alkyl aromatic hydrocarbon is carried out at a temperature below 130 ° C. The method according to claim 1, in which the oxidation of the alkyl aromatic hydrocarbon is carried out using oxygen, air or N / O mixtures with a Nc O ratio of 10: 1 to 1:10, at a pressure of 0.1 to 2 MPa (1 to 20 bar). 5. The process according to claim 1, wherein the oxidation of the alkyl aromatic hydrocarbon is carried out in the presence of a polar solvent selected from ketones, nitriles, esters, tertiary alcohols, dialkyl carbonates. The method according to claim 1 |
