“…It indicates that the suitable ratio of Si/Co is 60. However, the decrease in limonene conversion and carvone selectivity at higher cobalt content (Si/Co of 60) could be due to the presence of excess amount of cobalt, which leads to competent interaction of metal oxo-species with both alkylperoxy species and substrate [24,34].…”

“…The catalyst can be reused twice, without losing its activity to a great extent. 108 Using aqueous hydrogen peroxide and palladium(II) chloride for oxidation of differently substituted benzene rings of 2-phenylpyridines, lead to phenols in up to 74% yield. 109 The direct oxidations of benzene to phenol and anthracenes to anthraquinones with H 2 O 2 were achieved with Tp*Cu(NCMe)[Tp* = hydrotris(3,5-dimethylpyrazolylborate)] complexes as the catalysts.…”

This review presents the current state of the art of homogenic and heterogenic oxygen transfer processes using hydrogen peroxide as oxygen source and compounds and complexes of tranisition metals, Fe, V, Cu, Mn, Rh, Mo, Ti, W, Pd, Os, Zr, Cr, Nb, Co, as the catalysts. Based on the reactions of C-H, C-C and C=C bonds in alkanes, arenes and alkenes various mechanisms of the oxygen-transfer processes are discussed and new methodologies for synthesis of alcohols, phenols, aldehydes, ketones, epoxides and carboxylic acids are indicated.

“…2-Methyl-1,4-naphthoquinone (2-MNQ, CAS No. 58-27-5) is a chemical intermediate with promising future in the field of fine chemistry. − The preparation processes of 2-MNQ were studied. − On industrial scale, 2-MNQ was mainly produced via liquid-phase stoichiometric oxidation of 2-MN by CrO 3 in sulfuric acid with a yield of 40–60% causing many environmental problems. , 2-MNQ can also be synthesized by another method of vapor phase catalytic oxidation that our research group made many efforts to accomplish. The method developed the oxidation of 2-MN to 2-MNQ using molecular oxygen − in which a process with many byproducts with high content were always obtained.…”

The solid−liquid equilibria (SLE) in the ternary system of 2-methyl-1,4naphthoquinone (2-MNQ) + phthalic anhydride (PA) + 1,4-dioxane were determined experimentally by using the isothermal dissolution equilibriam method within temperatures 283.15, 293.15, and 303.15 K, respectively. The ternary phase diagram could be helpful in the separation of 2-MNQ and PA. On the basis of the experimental data on solubilities the phase diagrams of the system were plotted. Two pure solid phases were formed at 283.15, 293.15 and 303.15 K, including pure PA and pure 2-MNQ, which were confirmed and determined by Schreinemakers' wet residue method. The phase diagram at 283.15 K is similar to those at 293.15 and 303.15 K and the crystalline regions of 2-MNQ and PA decrease with increasing temperature. NRTL and Wilson model were employed to correlate and calculate the solubility data for the ternary system. A comparison between the two models shows that the NRTL model agrees better with the experimental data than those with the Wilson model. In addition, the densities of equilibrium liquid phase were obtained at the corresponding temperatures versus composition in the system.
