The solubility of CO2 and N2O in olive oil has been measured at temperatures of about 298, 310, and 323 K with a gravimetric microbalance under pressures up to 2 MPa. The molecular weight of olive oil has been analyzed and found to be about 882 g mol(-1) as a mixed oil compound. The observed solubility data have been correlated with a cubic equation of state (EOS) model. N2O has a larger solubility than CO2 in olive oil based on either the mole or mass fraction. The present results clarify some ambiguities from the previous N2O solubility data in the literature. (C) 2011 Elsevier B.V. All rights reserved.
