摘要： 用自行研制的二氧化碳溶解度测量仪在不同温度下测定了二氧化碳在不同氯化钠浓度15%葡萄糖水溶液中的溶解度和活度系数,确定了Henry常数和盐析常数,Henry常数与温度关系的经验方程为lgS=A/T+B+CT,并计算了二氧化碳溶解过程的各个热力学量。

关键词: 溶解度, 活度系数, 盐效应, 二氧化碳, 葡萄糖

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
