Abstract
Vapor pressure of aqueous solutions of lithium chloride were measured by differential static method, in a concentration range of 12.9-44.2% weight and in the temperature range of 30-100°C. The experimental data were fitted to the Antoine type equation: log P = A( m ) + B( m )/ T + C( m )/ T 2 , where A, B, and C are constants which are concentration dependent. Enthalpies of solution were calculated by the Haltenberger method using experimental vapor pressure data and heat capacity data. The Duhring and enthalpy-concentration charts have been constructed. These charts may be useful in the performance studies of absorption heat pumps.
