P.A. Meyers, David G. Shaw Solubility, Solubility data series (1) and (2) were placed in a glass stoppered flask fitted with a Teflon stopcock near the bottom. The components were equilibrated by gentle shaking for 12 hrs at 25.0 ± 0.1 °C. The mixture was then allowed to stand for 24 hrs. Samples removed via the stopcock were filtered with suction through 0.45 µm membrane filters to remove any hydrocarbon droplets. The filtrate was extracted three times with hexane and analyzed by gas chromatography. The International Union of Pure and Applied Chemistry Sutton, C.; Calder, J. A.; Environ. Sci.
