Abstract: The solubilities and activity coefficients of CO2 at various molalities of NaCl in 15 mass% glucose- water mixed solvent were measured.And Henry coefficients and constant of salting-out were determined from 278.15 to 318.15 K.The temperature dependence of Henry coefficients for CO2 can be expressed as empirical quations lgS=A/T+B+CT, and the thermodynamic quantities of the solution process for CO2 were calculated.

Key words: Solubility, Activity coefficient, Salt effect, CO2, Glucose
