Solubility of carbon dioxide in two pentaerythritol ester oils between 283 and 333 K
In this work, the solubility of carbon dioxide, CO2, in pentaerythritol tetrapentanoate (PEC5) and in pentaerythritol tetra(2- ethylhexanoate) (PEBE8) has been performed from (283 to 333) K and pressures up to 7 MPa in a new high-pressure gas solubility apparatus. The results show that in the present analyzed range CO2 is highly soluble in these oils and that the solubility expressed as CO2 mole fraction is practically not dependent on the branching
