摘要: A general gas-chromatographic method is proposed for determining mutual solubility of partially miscible organic solvents. The involves gradual increase the concentration one component in other region below their limit, parameters linear regression c = aS + b (c concentration, and S peak area), analysis saturated solutions components binary systems each (at ≈ const), calculating values from obtained equation. was tested by known data on hexane-acetonitrile hexane-nitromethane systems. Data hexane-2,2,2-trifluoroethanol perfluorodecalin-acetonitrile are first time; latter case, abnormally low revealed.
