Abstract
In order to utilize the brine resources in China, the solid-liquid equilibria in quaternary system Li+, K+//SOO 2–4 , B4O 2–7 -H2O at 288 K was studied by the isothermal solution equilibrium method. Solubilities and densities of solutions were determined experimentally. According to the experimental data, the equilibrium phase diagrams, density-composition diagram and corresponding water content diagram of the quaternary system were plotted. Double salt KLiSO4 was found in the reciprocal quaternary system Li+, K+//SOO 2–4 , B4O 2–7 -H2O at 288 K. The quaternary system has three invariant points, seven univariant curves and five fields of crystallization. The five crystallization regions correspond to Li2B4O7·3H2O, Li2SO4·H2O, K2B4O7·4H2O, K2SO4 and KLiSO4, respectively. The crystallization field of salt Li2B4O7·3H2O is the largest, whereas that of Li2SO4·H2O is the smallest. The experimental results show that Li2SO4·H2O has a strong salting-out effect on other salts.
