Peng-Robinson Cubic Equation of State Based on Key Group Contribution and Calculation of Nitrogen Gas Solubility in MMA Dimer

چکیده
Previously authors have reported facts that nitrogen (N2) and oxygen solubilities in styrene is the same as those benzene divinylbenzene at 303 K. Though three compounds an atomic composition, (CH)n (n=6, 8 10), gas are thought to depend on number of aromatic carbons solution. Then, named it ‘a key group solubility’. In this research, was investigated for N2 solubility methyl methacrylate (MMA) its dimer, ethylene glycol dimethacrylate (EGDMA). Therefore, calculations were carried out by Peng-Robinson (PR) equation state based contribution methods. The experimental data employed Lai et al., where MMA EGDMA assumed be double K, because has two units molecule. Two types methods proposed calculate EGDMA. One critical temperature pressure Joback Reid. Using these properties, attractive excluded volume parameters PR evaluated Other similar a method Orbey Sandler. parameter can from multiplying repeating units, squared number. Instead method, powers 3/4 3/2 perimeters, respectively. come scaling theory de Gennes. binary – also set k12 = 0.224, which –MMA. calculated far smaller than hypothetical Otherwise, reproduce solubility, quite different value, -0.044, necessary results suggested will not accepted MMA.

Surface Tension Prediction of n-Alkanes by a Modified Peng-Robinson Equation of State Using the Density Functional Theory
Through this study, the ability of a modified Peng-Robinson (MPR) equation of state in predicting the surface tension of n-alkanes based on the density functional theory approach was investigated and compared with other studies. The interfacial layer thickness and the density profile were calculated simultaneously at different temperatures from triple point to near critical point using the modi...
