Volume expansions and vapor-liquid equilibria of binary mixtures of a variety of polar solvents and certain near-critical solvents

摘要: Abstract Vapor-liquid equilibria for binary mixtures of polar solvents with either carbon dioxide, ethane, or ethene were determined a newly designed apparatus. Bubble-point curves three different temperatures. The densities the liquid phases also obtained. From these data volume expansions calculated. results show large differences in expansions, depending on system investigated. systems dioxide an interesting density behavior, which has no equivalent ethane systems. bubble-point modeled Peng-Robinson equation state (EOS).
