VAPOR-PRESSURES OF WATER PLUS LITHIUM-CHLORIDE PLUS ETHYLENE-GLYCOL AND WATER PLUS LITHIUM-CHLORIDE PLUS LITHIUM BROMIDE PLUS ETHYLENE-GLYCOL

Abstract

The vapor pressures of water + lithium chloride + ethylene glycol and water + lithium chloride + lithium bromide + ethylene glycol (LiCl/LiBr mass ratio 1:1) (H2O/C(2)HsO(2) mole ratio 10:1) were measured in the temperature ranges from 306.65 to 394.90 K and from 308.10 to 398.20 K and in the absorbent concentration ranges from 11.20 to 45.15 mass % and from 10.01 to 54.17 mass %, respectively. The experimental values were correlated with an Antoine-type equation, and the overall average absolute deviations between the experimental values and the calculated values were found to be 1.65% and 1.03% for the two systems, respectively.
