The solubility of CO2 and N2O in olive oil

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.
