VAPOR-PRESSURES OF THE ETHYLAMINE PLUS WATER PLUS LITHIUM BROMIDE SYSTEM AND ETHYLAMINE PLUS WATER PLUS LITHIUM-NITRATE SYSTEM

Vapor pressures of the ethylamine + water + lithium bromide (H2O:LiBr = 2:1 mass) system and the ethylamine + water + lithium nitrate (H2O:L iNO3 = 2:1 mass) system were measured by a boiling point method at tem peratures from 296.25 K to 318.25 K and at ethylamine concentrations f rom 4.8 to 59.4 mass lo, and at temperatures from 296.35 K to 316.25 K and at ethylamine concentrations from 4.8 to 64.0 mass %, respectivel y. The experimental vapor pressure data for these ternary systems were fitted to an Antoine-type equation. The calculated values from these equations for vapor pressures of two ternary systems were in good agre ement with the experimental vapor pressure data.
