Abstract
Values of reciprocal solubility of aliphatic hydrocarbons, some polar organic solvents, and their binary aqueous mixtures were determined at 20+/-1-degrees-C. The solubility of hydrocarbons in polar organic sol vents and their aqueous mixtures was established to be a single-valued function of methylene group increment (I(CH2)) and hydrocarbon molecu lar mass. The solubility of polar solvents in hydrocarbons depends on the hydrophilicity of the functional groups of the organic solvents, t heir hydrocarbon radical length, and on the hydrocarbon molecular mass . It was shown that growth of hydrocarbon molecular mass in some cases results in an abrupt drop in the reciprocal solubility of the hydroca rbon and polar organic or aqueous-organic components of the extraction system.
