Phase Behavior of the Reaction Medium of Limonene Oxidation in Supercritical Carbon Dioxide

Abstract

The main objective of this work is to investigate the phase behavior of the reaction medium for the limonene oxidation reaction at high pressures. For this purpose, the phase behavior of binary and ternary systems related to limonene oxidation in supercritical carbon dioxide was experimentally investigated. The experiments were carried out through the static synthetic method using a variable-volume view cell with two sapphire windows in the temperature range of 313−343 K at several overall compositions. The experimental data were modeled with the Peng−Robinson equation of state (PR-EOS) with the conventional quadratic mixing rule. The parameters fitted from binary systems were then used to simulate the phase behavior of ternary systems, and the results show that the PR-EOS is adequate to represent the experimental data.
