A New Empirical Equation for the Specific Thermal Capacity of Aqueous LiCl Solutions in a Wide Range of Conditions

Aqueous LiCl solutions are typical desiccants. Specific thermal capacity data, covering the temperatures range from 233.15 K to 343.15 K and salt mass fractions ranging from 0.15 to 0.45, have been obtained experimentally. The correlating equation proposed reproduces these experimental data with an average absolute deviation of 0.35 %, and a maximum absolute deviation of 1.15 %. Experimental data from the literature, and theory-based calculations, are reproduced by the new equation with a maximum deviation of 16.13 %, and 10.77 %, respectively.
