Thermal Conductivity of Liquid -1,2-Dichloroethene (R-1130(E)): Measurement and Modeling.

The thermal conductivity of liquid -1,2-dichloroethene (R-1130(E)) was measured at temperatures ranging from 240 K to 340 K and pressures up to 25 MPa using a transient hot-wire instrument. A total of 447 thermal conductivity data points were measured along six isotherms. Each isotherm includes data at nine pressures, which were chosen to be at equal density increments starting at a pressure of 0.

Structure and Dynamics of Hydrofluorocarbon/Ionic Liquid Mixtures: An Experimental and Molecular Dynamics Study.

The physical properties of four ionic liquids (ILs), including 1--butyl-3-methylimidazolium tetrafluoroborate ([CCim][BF]), 1--butyl-3-methylimidazolium hexafluorophosphate ([CCim][PF]), 1--butyl-3-methylimidazolium thiocyanate ([CCim][SCN]), and 1--hexyl-3-methylimidazolium chloride ([CCim][Cl]), and their mixtures with hydrofluorocarbon (HFC) gases HFC-32 (CHF), HFC-125 (CHFCF), and HFC-410A, a 50/50 wt % mixture of HFC-32 and HFC-125, were studied using molecular dynamics (MD) simulation. Experiments were conducted to measure the density, self-diffusivity, and shear viscosity of HFC/[CCim][BF] system. Extensive analyses were carried out to understand the effect of IL structure on various properties of the HFC/IL mixtures.
