Abstract: Solubilities of nitrogen in binary mixtures of n-octane and iso-octane have been measured over the temperature range of 20 to 70 ℃ and at pressures up to 130 atm. Experimental results can be fitted by the following equation
lnx_(N_2)=A+Bp_(N_2)+Cp_(N_2)~2+Dlnp
From the experimental results, the partial molar volume of dissolved nitrogen and the Henry's law constants have been calculated.
