Liquid-liquid equilibria for the (water + lactic acid + benzyl alcohol or p-xylene) ternary systems were investigated at atmospheric pressure and in the temperature range from 298.15-318.15 K. The studied systems exhibit two types of liquid-liquid equilibrium (LLE) behavior. The system consisting of benzyl alcohol displays type-1 LLE behavior, while a type-2 behavior is exhibited by th...

The catalytic activity of Pt/CNT for benzyl alcohol aerobic oxidation was remarkably improved by decorating iron oxide on Pt nanoparticles, and electrochemical measurements evidenced the enhanced activation of oxygen and benzyl alcohol at the FeO(x)/Pt interface.

An accurate, sensitive and selective reversed-phase micellar liquid chromatographic method was developed for simultaneous determination of benzyl alcohol and benzaldehyde. This method was applied in different injectable formulations containing diclofenac, piroxicam, lincomycin and clindamycin. The method showed excellent linearity in the range of 10-100 microg mL(-1) and 1-20 microg mL(-1) with...

The nucleotide sequences of xylB and xylC from Acinetobacter calcoaceticus, the genes encoding benzyl alcohol dehydrogenase and benzaldehyde dehydrogenase II, were determined. The complete nucleotide sequence indicates that these two genes form part of an operon and this was supported by heterologous expression and physiological studies. Benzaldehyde dehydrogenase II is a 51654 Da protein with ...

Ezlopitant is metabolized by cytochrome P450 primarily to two metabolites: a benzyl alcohol and a corresponding alkene. The alkene arises as a direct product of metabolism of ezlopitant rather than through dehydration of the benzyl alcohol. The mechanism of this cytochrome P450 (P450)-catalyzed dehydrogenation reaction was probed with five different deuterium-labeled analogs of ezlopitant. At s...

parameters and multiple regression analysis. The variation in the activity of N-(ca-substituted benzyl) derivatives was shown to be related parabolically with variation in the steric dimension of the substituents. The greater the hydrophobicity of substituents is, the greater the activity is. The variation in the steric dimension of the benzene ring substituents was responsible for the activity...

In the solvent free oxidation of benzyl alcohol, using supported gold-palladium nanoalloys, toluene is often one of major by-products and it is formed by the disproportionation of benzyl alcohol. Gold-palladium catalysts on acidic supports promote both the disproportionation of benzyl alcohol and oxidative dehydrogenation to form benzaldehyde. Basic supports completely switch off disproportiona...

The asymmetric unit of the title compound, C(26)H(25)N(3)O(2)S(2), contains two independent mol-ecules, which are linked by a pair of N-H⋯S hydrogen bonds, forming a dimer.

Two unique low-dimensional benzyl viologen iodoplumbates [Pb(13)I(38)][B'V](6) (1) and [(Pb(5)I(14))(BV)(2)](n) (2) were prepared from solvothermal reactions of benzyl alcohol with 4,4'-bipy, PbI(2), I(2) and a small amount of water in acetonitrile. The semiconducting properties of the single crystals 1 and 2 along with Zn/Cl-doped samples 2a and 2b were investigated.

A manganese(II) complex of 2,2’-bipyridine (bipy) was synthesized and characterized by X-ray diffraction, IR, and UV-vis spectroscopy. The activity of the complex was tested for oxidation of benzyl alcohols using t -BuOOH as an oxidant in organic solvents and in an organic/water biphasic system (hexane/H2O, toluene/H2O). The effect of solvent, temperature, oxidant, and some additives (KBr, N(C ...
