Abstract

A method of obtaining a multi-phase liquid system of artificial immiscibility the phases of which are suitable for use as selective solvents in the separation of substances, comprises selecting a solid, a dissolving liquid in which the solid is soluble, one or more non-dissolving liquids which are miscible with the dissolving liquid but not miscible with each other, and in which the solid is insoluble, and a standard relation of phase quantities, preparing a plurality of solutions of different proportions of the solid in the dissolving liquid, adding to each solution so much of the one or more non-dissolving liquids as to produce where possible a preliminary multi-phase system in which the quantities of the phases have the standard relation, and preparing the multi-phase liquid system by mixing the dissolving liquid, one or more non-dissolving liquids, and the solid in relative proportions which at least approximately correspond to the mean value of their relative proportions in each preliminary multi-phase system in which no crystallization of the solid and no chemical reactions between the constituents have been observed. A two-phase liquid system constituted by water, acetone and sodium chloride is used for the separation of ferric chloride from aluminium chloride, and ascorbic acid from glucose and saccharose. A two-phase system constituted by water, isopropyl alcohol and magnesium sulphate is used for the separation of lysine and arginine, aspartic acid and glutamic acid, extraction of adrenaline from an extract of suprarenal glands, separation of Vitamin B1 and B2. A two-phase system constituted by water, ethanol and ammonium sulphate is used to separate glycocoll and alanine. A two-phase system constituted by water, isopropanol and potassium chloride is used for the successive separation of glycocoll, alanine, valine, leucine and isoleucine; berberine and hydrastine in the form of their sulphates. A three-phase system constituted by water, acetone, petroleum ether and ammonium sulphate is used for the purification of insulin from pancreas extract, the purification of substances contained in liver tissue, the extraction of carotene from carrot pulp and chlorophyll from leaf pulp. Specification 733,617 is referred to.
