Solubilities of nitrogen in binary mixtures of n-octane and n-heptane have been measured at temperatures from 20 to 70 ℃ and pressures up to 130 atm using a precision gas-liquid solubility apparatus. Experimental results can be expressed by the following equation
Inx_(N_2)=A+BP_(N_2)+CP_(N_2)~2+DInP
From the results obtained, the partial molar volume of dissolved nitrogen and the Henry's Law constants have also been calculated.
