High-Pressure Vapor−Liquid Equilibrium for the Binary Systems Carbon Dioxide + Dimethyl Sulfoxide and Carbon Dioxide + Dichloromethane

High-pressure vapor−liquid equilibrium data were measured for two binary systems:  carbon dioxide + dimethyl sulfoxide at four temperatures from 309 to 329 K and pressures up to 13 MPa, and carbon dioxide + dichloromethane at 311.41 K and 326.95 K and pressures up to 9.5 MPa. Bubble points were dete...

Description
Summary:High-pressure vapor−liquid equilibrium data were measured for two binary systems:  carbon dioxide + dimethyl sulfoxide at four temperatures from 309 to 329 K and pressures up to 13 MPa, and carbon dioxide + dichloromethane at 311.41 K and 326.95 K and pressures up to 9.5 MPa. Bubble points were determined by a synthetic method where a mixture of known composition is prepared in a sapphire cell of variable volume. The reliability of the equipment and method was established through comparison with literature on the carbon dioxide + ethanol system. These measurements were made at 314.45 and 324.17 K.
