Improved Procedure for Hydrogen Peroxide Production by Oxidation of Secondary Alcohols and Oxygenated Cosolvents† / pilsar de Fruto Escrig in Industrial & engineering chemistry research, Vol. 47 n°21 (Novembre 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 n°21 (Novembre 2008) . - p.8025–8031 Titre : Improved Procedure for Hydrogen Peroxide Production by Oxidation of Secondary Alcohols and Oxygenated Cosolvents† Type de document : texte imprimé Auteurs : pilsar de Fruto Escrig, Auteur ; Alvaro garriga meco, Auteur ; ana padilla polo, Auteur Année de publication : 2008 Article en page(s) : p.8025–8031 Note générale : Chemical engineering Langues : Anglais (eng) Résumé : An improved procedure for the production of hydrogen peroxide via oxidation, with molecular oxygen, of secondary alcohols admixed with oxygenated co-solvents as primary alcohols and/or ether has been studied. The selectivity, conversion, and rates have been increased, in comparison to the data obtained in the absence of co-solvents. The increase observed in the oxidation rate of 1-phenylethanol in the presence of co-solvents has been interpreted using the chain co-oxidation reaction theory. The relative values of the termination constants of 1-phenylethanol and the tested co-solvents have been estimated. The lowest values of the termination constant of the peroxy radicals derived from the co-solvents explain the increase in the steady concentration of free radicals in the reaction media and, consequently, the enhancement observed in the co-oxidation rates.
