Herein, hierarchical bifunctional catalysts of Sn-USY-supported Au nanoparticles were designed for the one-pot conversion of glycerol (GLY) to methyl lactate (MLA). Over Au/Sn-USY catalyst, 79% MLA yield can be obtained with a high selectivity (∼90%). The promotion effect of Sn was investigated, and the interaction between extraframework SnO x and Au was confirmed by TEM, pyridine-FT-IR, CO-FT-IR, and XPS. The interaction promotes the dispersion of Au particles (smaller and much more uniform). This is important for the oxidation of GLY to 1,3dihydroxyacetone (DHA) and glyceraldehyde (GA), which are the intermediate species for the conversion of GLY to MLA. Meanwhile, introduction of Sn modified the acid properties of the catalyst, which are critical for the selective conversion of DHA and GA to MLA.

Using a laser monitoring observation technique, the solubilities of p-aminophenol in sulfuric acid + water have been determined experimentally from 286.15 K to 362.80 K. The experimental data were correlated with the modified Apelblat equation. The calculated results showed good agreement with the experimental data.

To provide thermodynamic data for isonicotinic acid production, the solubilities of isonicotinic acid in water and 4-methylpyridine binary solvent mixture were determined from (287.65 to 361.15) K with the solvent mole fraction composition ranging from 0.00 to 1.00. The experimental data were correlated with the modified Apelblat equation. The calculated results show good agreement with the experimental data.

The solubilities of 2-methyl-1,4-naphthoquinone in water + (methanol, ethanol, 1-propanol, 2-propanol, 1,2-propanediol, and glycerin, respectively) have been determined experimentally from (293.15 to 337.92) K by balanced method. The experimental data were correlated with the modified Apelblat equation.

The densities and viscosities of niacin + 3-picoline + water mixtures have been determined experimentally at temperatures from 293.15 K to 343.15 K. The apparent molar volumes were calculated from experimental measurements. Results were fit to obtain the adjustable parameters and standard deviations between the measured and fit values.

The densities and viscosities for binary mixtures of vitamin K3 + benzene, toluene, ethylbenzene, o-xylene, m-xylene, and p-xylene, respectively, have been determined experimentally under normal atmospheric pressure over the entire molality range from (303.15 to 333.15) K. The apparent molar volumes of vitamin K3 were calculated from experimental measurements. Results were fit to obtain the appropriate parameters and standard deviations between the measured and fitted values.

Using the laser monitoring observation technique, the solubilities of dimethyl fumarate in methanol, ethanol, 1-propanol, 2-propanol, 1,2-propanediol, and water have been determined experimentally from (289.95 to 347.15) K. The experimental data were correlated with the modified Apelblat equation. The calculated results showed good agreement with the experimental data.
