“…The solubilities of SO 2 F 2 in physical solvents can be expressed by the following equations where x is the mole fraction of gas absorbed; n g is the moles of gas absorbed; n s is the moles of solvent added; m is the molality of gas absorbed; w s is the mass of solvent added; M is the mean molecular weight of solvent; n 0 is the initial amount of the gas in GR; n 1 is the amount of gas left in GR after entering the EC step; ( n 0 – n 1 ) is the total amount of the gas entering EC; and n e is the amount of gas at the equilibrium state. The values of n 0 , n e , and n 1 can be calculated from PVT data by the Soave–Redlich–Kwong (SRK) equation of state …”

A large amount of sulfuryl fluoride (SO2F2) is released into the atmosphere after fumigation, intensifying the greenhouse effect. Therefore, it is important to remove SO2F2 generated in fumigation. In this study, the solubilities of SO2F2 in 2-butoxyethyl acetate (BOEA), 3-methoxybutyl acetate (MOBA), 2-methoxyethyl acetate (MOEA), 1-methoxy-2-propyl acetate (MOPA), and 2-(2-ethoxyethoxy)ethyl acetate (DEOEA) were determined at T = (293.15 to 323.15) K and pressures up to about 600 kPa using the isochoric saturation method. Results showed that SO2F2 solubility in the five acetate derivatives increased with increasing pressure and decreased with increasing temperature. The dissolution of SO2F2 in these solvents belonged to a physical process. Furthermore, the Henry’s law constants and thermodynamic properties including standard Gibbs free energy, enthalpy, and entropy changes of SO2F2 dissolution were further obtained. Compared with water, these five selected acetate derivatives showed potential application for SO2F2 removal. Moreover, the solubilities of SO2F2 in these solvents followed the order of MOBA > MOPA > BOEA > DEOEA > MOEA.

The solubilities of acetylene in 1,4-butylene glycol, diethylene glycol, linalool, ethylene glycol, isopropanol, isobutanol, butyl alcohol, 1-methyl-2-pyrrolidinone, 2-pyrrolidinone, N-vinylpyrrolidone, 6-methyl-5-hepten-2-one, and geranyl acetone were studied in the temperature range of 278.15 to 318.15 K and in the pressure range of 0.03 to 0.25 MPa. The Henry's law constants were calculated from the slope of the linear isotherms of pressure versus the mole fraction of acetylene. Thermodynamic properties such as the Gibbs free energy, enthalpy, and entropy changes of dissolution of acetylene in the alcohols and ketones were calculated.
