Measurement and prediction of (solid + liquid) equilibrium for sulfur compounds with aliphatic hydrocarbons

(Solid + liquid) equilibrium (SLE) of thiophene or diethylsulfide with n-heptane, n-octane or n-dodecane mixtures was measured by a static method. All the systems under study are simple eutectic systems. The DISQUAC group contribution model is fairly successful in predicting SLE.
