thermodynamic properties of Dimethyl Phthalate along the vapour liquid saturation curve
The Journal of Chemical Thermodynamics, 1999Co-Authors: Vladislav Roháč, Jana E Musgrove, Květoslav Ružicka, Vlastimil Ruzicka, Milan ZabranskýAbstract:Abstract Measurements of vapour pressurep, densityρ, and molar heat capacityCp,mare reported for Dimethyl Phthalate in the liquid phase. The methods of comparative ebulliometry, vibrating-tube densimetry, and heat conduction calorimetry were employed to determine these properties. A simultaneous correlation of vapour pressures and of enthalpy of vaporizationΔvapHmwas used to generate parameters for the Cox equation. Vapour pressure and enthalpies of vaporization derived from the fit are reported at the triple point temperatureTt, atT = 298.15 K, and at the normal boiling temperature. For inclusion into program packages, parameters of the Antoine equation were calculated by fitting the ebulliometric vapour pressures. A comparison of all measured properties with literature data is presented.

liquid liquid equilibria of water propionic acid Dimethyl Phthalate at several temperatures
The Journal of Chemical Thermodynamics, 2005Co-Authors: Dilek Özmen, Süheyla Çehreli, Umur DramurAbstract:Abstract (Liquid + liquid) equilibrium (LLE) data for (water + propionic acid + Dimethyl Phthalate) were measured under atmospheric pressure and at T = (298.2, 303.2, 308.2 and 313.2) K. Phase diagrams were obtained by determining solubility and tie-line data. The LLE data of the ternary systems were predicted by UNIFAC method. Distribution coefficients and separation factors were evaluated over the immiscibility regions.

Liquid-liquid equilibria of water + acetic acid + phthalic esters (Dimethyl Phthalate and diethyl Phthalate) ternaries
Journal of Chemical & Engineering Data, 1993Co-Authors: Umur Dramur, Beşir TatliAbstract:Experimental liquid-liquid equilibria of water+acetic acid+Dimethyl Phthalate and water+acetic acid+diethyl Phthalate systems were investigated at 293.16±0.20 K. The reliability of experimental tie-line data was ascertained through an Othmer-Tobias plot. Distribution coefficients and separation factors were evaluated over the immiscibility region. It is concluded that the high-boiling solvents Dimethyl Phthalate and diethyl Phthalate are suitable separating agents for dilute aqueous acetic acid solutions

catalytic ozonation of Dimethyl Phthalate with ruo2 al2o3 catalysts prepared by microwave irradiation
Catalysis Communications, 2013Co-Authors: Jianbing Wang, Junyang Cheng, Can Wang, Shaoxia Yang, Wan-peng ZhuAbstract:Abstract Ruthenium catalysts supported on alumina were synthesized by microwave irradiation and used to catalyze ozonation of Dimethyl Phthalate in water. The catalysts enhanced greatly the TOC (total organic carbon) removal. The contribution of catalysis and adsorption to the overall TOC removal were 33% and 50%, respectively. 300 W was the optimal irradiation power for catalyst preparation. Moisture content had little effect on the catalytic activity. Compared to conventional irradiation, microwave irradiation benefited the catalytic activity because it provided a homogeneous dispersion of metal on the support. It is a promising thermal treatment method for developing the catalysts used in catalytic ozonation.

Catalytic oxidation of Dimethyl Phthalate in aqueous solution by aluminum oxide
Huan jing ke xue= Huanjing kexue, 2006Co-Authors: Yun-rui Zhou, Wan-peng ZhuAbstract:With Dimethyl Phthalate as the model pollutant and alumina as catalyst, the degradation of TOC system was systemically investigated. Results show that Al2O3 can significantly increase the effect of ozonation, and TOC removal rate in 120 minutes can reach 55.1% while only 23.9% with alone ozone. Al2O3 activeness is upmost under the follow conditions: calcination temperature, 600 degrees C; particle diameter, 0.5 - 1 mm; catalyst dosage, 20 g/L; gas flow rate, 200 mL/min, react temperature, 15 degrees C. The contrastive experiments of alone ozone, catalyst adsorption after ozonation and catalytic ozonation confirmed that catalytic reaction is the most important process to TOC removal in system with alumina as catalyst.
