Molecular Dynamics Simulation of Transport and Structural Properties of CO2 Using Different Molecular Models

26.06.2015 | Haimin Zhong; Shuhui Lai; Jinyang Wang; Wenda Qiu; Hans-Dietrich Lüdemann; Liuping Chen, Journal of Chemical & Engineering Data, 2015

The diffusion coefficients (Ds), viscosities (η), and structural properties of carbon dioxide (CO2) have been studied using molecular dynamics (MD) simulation. Three fully flexible models (MSM-flex, EPM2-flex, and TraPPE-flex) from the literature are used to model CO2. Present simulations have ...

Solubility of 2,5-Di-tert-butylhydroquinone and Process Design for Its Purification Using Crystallization

25.06.2015 | Yang Zhang; Jing Jing Liu; Lei Zhang; Xue Zhong Wang, Journal of Chemical & Engineering Data, 2015

The solubility of 2,5-di-tert-butylhydroquinone (DTBHQ) in acetone, ethyl acetate, methanol, and the mixtures of ethanol and water was measured and correlated in the temperature range between 278.95 K and 346.15 K. It was found that the solubility in acetone increases more rapidly with increasing ...

High-Pressure Phase Behavior of Poly(l-lactic acid), Trichloromethane, and Carbon Dioxide Ternary Mixture Systems

24.06.2015 | Taehyun Im; JungMin Gwon; Soo Hyun Kim; Hun Yong Shin; Hwayong Kim, Journal of Chemical & Engineering Data, 2015

In this study, the phase behavior of a poly(l-lactic acid) (M = 312 000, polydispersity 2.189)–trichloromethane–carbon dioxide ternary system was measured using a variable volume view cell at pressures up to 34.0 MPa and temperatures between (313.15 K and 363.15) K at an interval of 10 K. Bubble ...
