ABSTRACT

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 a temperature range of 278.15 to 318.15 K and at pressure from 0.03 to 0.25 MPa. The Henry's law constants were calculated from the slope of 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.
