Studies in chemical phase analysis. Part I. Determination of the solubilities of elements in certain organic solvent-bromine mixtures

Abstract

As part of a study on the quantitative separation of carbide, nitride, oxide and sulphide inclusions from metals, the solubilities of aluminium, chromium, cobalt, copper, iron, lead, manganese, molybdenum, nickel, niobium, phosphorus, silicon, sulphur, tin, titanium, tungsten and vanadium have been determined at 25 °C in organic solvent-bromine mixtures (10 + 1 V/V) after refluxing. The solvents were methyl acetate, butyl acetate and acetonitrile. All of the above elements except lead, molybdenum, silicon and tungsten were appreciably or very soluble in these solvents. Molybdenum was sparingly soluble and the others almost insoluble.
