Inhibitory effect of inorganic ions on nitrobenzene oxidation by fluidized-bed Fenton process

Abstract: This study investigated the effects of inorganic ions including chloride ions, dihydrogen phosphate ions and nitrate ions on the oxidation of nitrobenzene by the fluidized-bed Fenton process. The nitrobenzene degradation decreased with increasing chloride, dihydrogen phosphate and nitrate concentrations. Dihydrogen phosphate and chloride ions significantly inhibited nitrobenzene degradation. However, the inhibition caused by chloride ions could be overcome by extending the reaction time if the concentration of chloride ions was low. Nitrate did not have significant effect on nitrobenzene removal. The inhibition effect of each inorganic ion on the nitrobenzene degradation was in the order: H2PO4− ≫ Cl− > NO3−. In addition, the results also show that the removal efficiency of nitrobenzene by fluidized-bed Fenton process was higher than traditional Fenton process.

Densities and Viscosities of Binary Liquid Mixtures of Anisole or Methyl tert-Butyl Ether with Benzene, Chlorobenzene, Benzonitrile, and Nitrobenzene

Abstract: Densities and viscosities for the binary liquid mixtures of anisole or methyl tert-butyl ether (MTBE) with benzene, chlorobenzene, benzonitrile, and nitrobenzene were measured at 288.15, 293.15, and 298.15 K. These were used to compute the excess volumes (VE) and deviations in viscosity (Δη). These properties are discussed with reference to the nature of interactions between the unlike molecules.

A homogeneous catalyst made of poly(4-vinylpyridine-co-N-vinylpyrrolidone)-Pd(0) complex for hydrogenation of aromatic nitro compounds

Abstract: Poly(4-vinylpyridine-co-N-vinylpyrrolidone)(VPy-co-NVP) and its palladium complex (VPy–NVP–Pd) were prepared. The palladium complex was used as catalyst for the hydrogenation of some nitroaromatics. The molar content of VPy units in VPy-co-NVP was determined as 31.25% by 1H NMR. VPy–NVP–Pd can be easily resolved in ethanol forming a homogeneous catalytic hydrogenation system together with substrates. The optimum catalytic activity for hydrogenation of nitrobenzene appeared when VPy/Pd molar ratio was 2. The catalytic behavior of the catalyst was found to be greatly affected by the type and concentration of added alkalies. The highest hydrogenation rate for nitrobenzene was found in a 0.1 mol/l ethanol solution of potassium hydroxide. The catalytic stability was examined by using nitrobenzene and 4-nitroanisole as substrates.
