Green Catalytic Oxidation of Cyclohexanone to Adipic Acid
Synthesis of adipic acid by catalytic oxidation of cyclohexanone with 30% hydrogen peroxide in the presence of sodium tungstate catalyst can be well performed under reflux temperature. The adipic acid isolated yield reaches to 82.1%, and the purity of the product is also very high. The catalytic oxidation reaction takes place without any organic solvent and phase-transfer agent. The effects ove...
متن کاملOxidation of Cyclohexanone and Cyclohexanol to Adipic Acid Using Hydrogen Peroxide and Supercritical Carbon Dioxide
Supercritical carbon dioxide and hydrogen peroxide was used in the oxidation for exploring a clean and efficient process to produce adipic acid. Supercritical carbon dioxide would be both a solvent and reactant in combination with aqueous hydrogen peroxide, which made the oxidation be possible through the formation of peroxycarbonic acid as the intermediate oxidizer. The effects of temperature ...
متن کاملSelective nickel-catalyzed conversion of model and lignin-derived phenolic compounds to cyclohexanone-based polymer building blocks.
Valorization of lignin is essential for the economics of future lignocellulosic biorefineries. Lignin is converted into novel polymer building blocks through four steps: catalytic hydroprocessing of softwood to form 4-alkylguaiacols, their conversion into 4-alkylcyclohexanols, followed by dehydrogenation to form cyclohexanones, and Baeyer-Villiger oxidation to give caprolactones. The formation ...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولAdipic acid tolerance screening for potential adipic acid production hosts
BACKGROUND Biobased processes for the production of adipic acid are of great interest to replace the current environmentally detrimental petrochemical production route. No efficient natural producer of adipic acid has yet been identified, but several approaches for pathway engineering have been established. Research has demonstrated that the microbial production of adipic acid is possible, but ...
