The vapour pressures of concentrated aqueous lithium bromide solutions were measured at temperatures ranging from 120 deg C to 210 deg C. Five solutions of salt mass fractions - 0.437, 0.494, 0.549, 0.608, and 0.652 - were investigated. A novel representation of salt solution vapour pressure over a large range of temperature and concentrations using a minimum of parameters was developed. The data from this study were successfully correlated using the proposed model. Previously published vapour pressure measurements were also reviewed and checked for consistency. The results of this work will allow the development of more reliable P-T-x charts for aqueous lithium bromide solutions over a large range of conditions.
