متن کاملExperimental and theoretical studies on green and efficient deoximation using H202 catalyzed by Montmorillonite-K10 supported MnC12
Oximes were oxidized to the corresponding carbonyl compounds in good to high yields by ecofriendlyand green oxidant, H202 catalyzed by Montmorillonite K-10 supported Mangenese(II)Chloride. The structures of these compounds were favorably compared with the results of ab initiocalculations at three temperatures. Computational methods allow for the visualization of largeamounts of structural data ...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
An efficient and selective method for conversion of oximes, semicarbazones and phenylhydrazones to the corresponding carbonyl compounds under solvent-free conditions
o-Xylylenebis (triphenylphosphonium peroxymonosulfate) (1) was easily prepared from an aqueous solution of oxone and o-xylylenebis- (triphenylphosphonium bromide). This Compound (1) is a useful and selective reagent for conversion of oximes, semicarbazones and phenylhydrazones to the corresponding carbonyl compounds. The reaction was carried out under solvent-free conditions and in the presence...
