ABSTRACT
This work reports experimental phase equilibrium data the for ternary system involving caprolactone, carbon dioxide and dichloromethane. Such data provide fundamental information to conduct polymerization reactions in supercritical carbon dioxide medium. The experiments were performed using a variable-volume view cell over the temperature range from 323.15 to 353.15 K and different mass ratios of dichloromethane to -caprolactone (0.5:1, 1:1 and 2:1). Phase transitions of vapor-liquid at the bubble point (VLE-PB), liquid-liquid (LLE) and vaporliquid-liquid (VLLE) types were observed. The experimental results were modelled using the Peng-Robinson EoS with the van der Waals mixing rule, resulting in a good representation of experimental phase equilibrium data.
