摘要
A new model for 2,2,2-trifluoroethano1 is proposed. It is a 7-atom model with the methylene group treated as an united atom. The model was optimized to reproduce the physicochemical properties of the pure liquid. The properties of the new model were compared with the available experimental data over a range of temperatures. Furthermore, mixtures with the SPC water model were simulated to assess the ability to reproduce available thermodynamic and kinetic data as well as dielectric properties. The model provides a good agreement with experimental data for the neat liquid and for mixtures with water.
