ABSTRACT
The solubility of carbon dioxide in pentaerythritol tetra-2-methylhexanoate between 243.15 K and 343.15 K and between 0.1 MPa and 10 MPa is presented, together with a comparison with the already studied systems of carbon dioxide and pentaerythritol esters, i.e. pure precursors of commercial lubricants. The experimental data were regressed on the basis of the Peng Robinson equation of state with the Huron Vidal mixing rules with the excess Gibbs energy at infinite pressures.
