THE SYSTEMS SODIUM CHLORATE – WATER – DIOXANE AND LITHIUM CHLORATE – WATER – DIOXANE, AT 25°

Abstract

The phase diagrams of the systems sodium chlorate – water – dioxane and lithium chlorate – water – dioxane have been determined at 25 °C.The sodium chlorate – water – dioxane diagram is relatively simple, anhydrous sodium chlorate being the only solid phase. The occurrence of two liquid layers in contact with sodium chlorate is found between dioxane concentrations of 67.7 and 88.8%.The lithium chlorate – water – dioxane system exhibits both complex formation and a ternary miscibility gap. The lithium chlorate hydrate, [Formula: see text] exists from 0 to 2.2% dioxane. A mole to mole compound of lithium chlorate and dioxane, LiClO3•C4H8O2, exists from 2.2% dioxane to 100% dioxane. There exists a ternary miscibility gap between dioxane concentrations of 81.5 and 93.6%The X-ray powder data for anhydrous lithium chlorate, its quarter hydrate, and the compound of lithium chlorate and dioxane have been obtained.
