Fe(3)O(4):PVP/Au nanocomposite synthesized via a two-step procedure was tested as a quasi-homogenous alcohol oxidation catalyst. It was found that the nanocomposite was able to carry out aerobic oxidation of alcohols in water at room temperature. Studies show rapid magnetic recoverability and reusability characteristics.

Ilicic alcohol, a natural sesquiterpene, was converted into an aldehyde by using Jones’ oxidation. The gastroprotective activity of ilicic aldehyde was evaluated in mice and rats.

vanadium phosphorus oxides (vpo) has been applied as a heterogeneous catalyst in gas phase oxidation reactions and its application is very limited in liquid phase. in this study a series of cobalt-doped vanadium phosphorus oxides (vpo-co) catalysts with different loading of co (0.01-1.0 mol ratio of co/v) were prepared. oxidation of benzyl alcohol was studied in the liquid phase over vpo and vp...

A hepatic microsomal ethanol-oxidizing system is described both in men and rats. It is distinguished from alcohol dehydrogenase by its subcellular localization (cytosol for alcohol dehydrogenase, microsomes for this system), its pH optimum (physiological pH versus pH 10 to 11 for alcohol dehydrogenase), and its cofactor requirements (NADPH versus NAD+ for alcohol dehydrogenase). It also require...

The silylium ion-catalysed reduction of carbonyl compounds to the alcohol oxidation level is accomplished by exploiting the unique reactivity of a ferrocenyl-substituted silane.

A series of transition metal complexes with two thiosemicarbazide Schiff bases, 1-(4-dimethylaminobenzyl- idene)thiosemicarbazide (ABTSC) and 1-(2-pyridincarboxyl-idene) thiosemicarbazide (TCTS) were synthesized with Co(II), Ni(II), Zn(II), Cd(II) and Ag(I) salts (chloride and acetate). These complexes were characterized by different methods including proton nuclear magnetic resonance (1HNMR),...

Well faceted CuO nanoparticles, were synthesized by thermal-assisted dissociation method at reflux temperature in a short period of time. A possible mechanism for synthesis of such highly pure and stable nanoparticles is tentatively proposed by FT-IR study. The large surface area and rich exposed active sites are expected to endow such nanoparticles with excellent performances in catalysis as d...

The discovery that macrophages metabolize ethanol to acetate in vitro may be of importance in understanding the pathogenesis of ethanol-induced tissue damage (1) . When expressed per unit wet weight, the rate of metabolism ofethanol by these cells is comparable to that by hepatocytes (2) . Studies of human and murine macrophages derived from various tissues have revealed that ethanol oxidation ...
