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.File in questo prodotto:
