Experimental Determination and Calculation of Gas Solubility Data for Nitrogen in Different Solvents

Gas solubility data (isothermal P − x data) for nitrogen in different solvents ( n -hexane, 1-hexene, benzene, toluene, acetone, propionic aldehyde, ethyl acetate, n -butyl acetate, ethyl formate, methyl formate, n -butylamine, diethylamine, dipropylamine, triethylamine, aniline, pyridine, acetonitrile) were measured using the static synthetic method at temperatures from 303.15 K to 393.15 K, and pressures up to ∼3.5 MPa. From these data, Henry coefficients were derived. The obtained data were compared to published data and used to fit new group interaction parameters for the volume-translated Peng−Robinson (VTPR) group contribution equation of state.
