Isobaric Vapor-Liquid Equilibrium for Methyldichlorosi-lane+Methylvinyldichlorosilane+Toluene and Constituent Binary Systems

摘要

Vapor-liquid equilibrium (VLE) for a ternary system of methyldichlorosilane + methylvinyldichlorosi-lane + toluene and constituent binary systems were measured at 101.3kPa using a new type of magnetical pump-ebulliometer. The equilibrium compositions of the vapor phase of binary system, were calculated indirectly from the total pressure-temperature-liquid composition (pTx). The experimental data were correlated with the Wilson and NRTL(non-random two liquid) equations. The parameters of the Wilson model were employed to predict the ternary VLE data. The calculated boiling points were in good agreement with the experimental ones.
