Abstract: 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
From the results obtained, the partial molar volume of dissolved nitrogen and the Henry's Law constants have also been calculated.

Key words: Mixed solvents of n-octane and n-heptane, Solubilities, Precision gas-liquid solubility apparatus
