Abstract

Solubilities in the Li2MoO4-n-C4H9OH-H2O system at 25°C have been studied. New chemical compounds are not formed in the system. The miscibility of the solvents noticeably decreases with increasing Li2MoO4 concentration. The C4H9OH solubility decreases from 7.45 wt % in neat water to 0.01 wt % in a saturated (44.40 wt %) aqueous solution of Li2MoO4. The H2O solubility in n-C4H9OH decreases from 20.48 to 5.50 wt % in the presence of trace amounts of Li2MoO4. In the invariant state, saturated liquid phases (\(L_{E_1 } \) and \(L_{E_2 } \)), which are in equilibrium with solid Li2MoO4, have the following compositions (wt%): for \(L_{E_1 } \), 43.94% Li2MoO4, 0.01% C4H9OH, and 56.05% H2O; and for \(L_{E_2 } \), 0.0011% Li2MoO4, 94.50% C4H9OH, and 5.50% H2O. The density, refractive index, dynamic viscosity, and electrical conductivity of the saturated solutions of the system have been determined. The isotherms have been calculated for the specific and molar volumes, kinematic viscosity, and equivalent and reduced electrical conductivity of the solutions.
