Phase Diagram of LiCl-HOAc and LiCl-HOAc-H2O(at25℃) Systems

Abstract

Abstract: The solubilities of saturated solutions of the title systems have been investigated and the corresponding equilibrium phase diagrams were constructed.As shown in the phase diagram of LiCl-HOAc, there are two solid phases:LiCl and the solvate compound LiCl · (l/2)HOAc, which is soluble incongruently.No LiCl · HOAc and LiCl · 5HOAc have been found.There are three solid phases:LiCl · H₂O, LiCl and LiCl ·(1/2)HOAc in the phase diagram of LiCl-HOAc-H₂Osystem at 25℃.The changes of the phase LiCl · H₂O·LiCl·LiCl · (1/2)HOAc were observed and shows saltingin, anhydration and solvate action of HOAc.Based on the phase diagram of LiCl-HOAc-H₂Oternary system, a new method for preparing anhydrous LiCl may be suggested.

Key words: Binary system, Ternary system, LiCl, HOAc, Phase equilibrium
