Saturated Vapor Pressure of 4 fluorophthalic anhydride and 4 chlorophthalic anhydride and isobaric Vapor liquid phase equilibrium of 4 fluorophthalic anhydride 4 chlorophthalic anhydride measurement and modeling
Fluid Phase Equilibria, 2015Co-Authors: Shuo Han, Jing Wang, Ganbing Yao, Hongkun ZhaoAbstract:Abstract The Saturated Vapor Pressures of 4-fluorophthalic anhydride and 4-chlorophthalic anhydride at various temperatures ranging from T = (426 to 560) K, and the isobaric Vapor–liquid phase equilibrium data for binary system of 4-fluorophthalic anhydride (1) + 4-chlorophthalic anhydride (2) at Pressures of 21.33 kPa, 41.33 kPa, 61.33 kPa and 81.33 kPa were measured experimentally by means of an inclined ebulliometer. The relationship between Saturated Vapor Pressure and temperature was fitted by using two Antoine equations and the Antoine constants were acquired for 4-fluorophthalic anhydride and 4-chlorophthalic anhydride, respectively. The semi-empirical method, Herington method was employed to test thermodynamic consistency of the Vapor–liquid equilibrium data. The isobaric Vapor–liquid phase equilibrium data were fitted with three thermodynamic models, which corresponded to Wilson, NRTL and UNIQUAC. The parameters of the three activity coefficient models were obtained by the method of nonlinear least-square regression. The calculated Vapor–liquid phase equilibrium data with the three activity coefficient models agree very well with the experimental values.

Vapor Pressure and isobaric Vapor liquid equilibrium for dichloronitrobenzene isomers
Fluid Phase Equilibria, 2014Co-Authors: Ganbing Yao, Zhipeng Yang, Bin Zhang, Hongkun ZhaoAbstract:Abstract The Saturated Vapor Pressures of pure 3,4-dichloronitrobenzene and 2,3-dichloronitrobenzene and the isobaric Vapor–liquid equilibrium (VLE) data for binary 3,4-dichloronitrobenzene + 2,3-dichloronitrobenzene system under 20.00 kPa, 60.00 kPa and 101.30 kPa were measured experimentally using an inclined ebulliometer. The Saturated Vapor Pressure was correlated by an Antoine equation. Thermodynamic consistency of the Vapor–liquid equilibrium data was tested by means of Herington semi-empirical method, and the Vapor–liquid equilibrium data were correlated with Wilson, NRTL and UNIQUAC activity coefficient models. The parameters of the three thermodynamic models were obtained by a nonlinear least-square regression method. All the three models can describe the measured Vapor–liquid data satisfactorily. The Vapor Pressures and the Vapor–liquid equilibrium data presented in the paper are essential for the design and operation for separation of the isomeric mixture of 3,4-dichloronitrobenzene + 2,3-dichloronitrobenzene via distillation.

Saturated Vapor Pressure and gaseous pvt property measurements for 3 3 3 trifluoroprop 1 ene r1243zf
International Journal of Refrigeration-revue Internationale Du Froid, 2020Co-Authors: Jianguo Yin, Guanjia ZhaoAbstract:Abstract 3,3,3-trifluoroprop-1-ene (R1243zf) is a potential alternative refrigerant with low global warming potential and 26 Saturated Vapor Pressure data and 128 Vapor phase pvT data are presented in this paper. The Vapor Pressure data were obtained in the temperature range from (253 to 376) K and Pressure range from (0.13 to 3.46) MPa. The Vapor phase pvT data were measured using a Burnett apparatus for the temperature range from (253 to 368) K, Pressure range from (0.11 to 2.89) MPa and density range from (0.05 to 1.82) mol dm–3. The standard experimental uncertainties were estimated as 5 mK and 0.5 kPa for temperature and Pressure, respectively. The relative uncertainty in density is better than 0.12%. In addition, the present pvT data were correlated by a truncated virial equation of state with the density average absolute relative deviation of 0.05%.

International Journal of Refrigeration-revue Internationale Du Froid, 2019Co-Authors: Jianguo Yin, Guanjia ZhaoAbstract:Abstract The Saturated Vapor Pressures and gaseous pvT properties of 2,3,3,3-tetrafluoroprop-1-ene (HFO-1234yf) were measured using a Burnett apparatus. 24 Vapor Pressure data points were obtained in temperature range from (253 to 367) K and with Pressures from (0.15 to 3.34) MPa. The standard experimental uncertainties were estimated to be within 5 mK and 0.5 kPa for temperature and Pressure, respectively. The Vapor Pressure data were correlated by a Wagner type equation with the average absolute deviation of 0.015%. A total of 172 gaseous pvT data were obtained in temperature range from (253 to 368) K, Pressure range from (0.097 to 3.37) MPa and density range from (0.038 to 2.86) mol dm–3. The relative uncertainty in density is better than 0.15%. The present data were correlated by a truncated virial equation of state with the average absolute deviation of 0.03% in density.

measurement and correlation of isobaric Vapor liquid equilibrium for binary systems of 1 ethoxymethoxy 2 methyl propane with isobutyl alcohol or 1 butanol at 101 33 kpa
Journal of Chemical & Engineering Data, 2017Co-Authors: Yu-he Song, Shu-e Wang, Hui Hua, Juan Song, Ping-he WeiAbstract:Experimental Vapor–liquid equilibrium (VLE) data for binary systems of 1-(ethoxymethoxy)-2-methyl-propane (EMMP) with isobutyl alcohol and 1-butanol at 101.33 kPa was measured. The measurements of Saturated Vapor Pressure for EMMP were also measured. The experiment was performed by an improved Rose still. A minimum boiling azeotrope was found about the binary system containing 1-butanol for which the azeotropic temperature and composition are 389.64 K and 75.92 mol% (1-butanol) at 101.33 kPa. The VLE measurements were correlated by the Wilson, nonrandom two-liquid, and universal quasichemical models for which the results showed that the measurements had a good correlation by using three models about two binary systems, respectively. The thermodynamic consistency of the VLE measurements was checked by the traditional area test and the direct test methods.
