摘要
Solubilities of CO2 in binary mixtures of n-decane-n-hexadecane and n-heptane-toluene were measured in a glass apparatus by a synthetic method. Henry's constants at several temperatures and solvent compositions were reported. While the Henry's constants of CO2 in mixtures of decane and hexadecane can be satisfactorily predicted by a simple linear interpolation, prediction of Henry's constants for CO2 in mixtures of heptane and toluene requires excess Gibbs energy of the solvent. mixtures. The standard thermodynamic functions of solution (Delta H degrees, Delta G degrees and Delta S degrees) were reported.
