Szafranski Solubility, Solubility data series A mixture of (1) and (2) was equilibrated at 25 ± 0.1 °C for a minimum of 12 hrs in a 200-mL Teflon-stoppered vessel (25 cm long and 3.5 cm across) with gentle shaking, allowed to settle for 6 hrs and tested for the absence of emulsion (Tyndall effect). The aqueous and organic phases were analyzed by GLC with internal standardization) on a Hewlett-Packard Model 700 instrument equipped with a 15% SE-30 on 60/80 mesh acid-washed $\ce{(CH3)2Cl2Si}$-treated Chromosorb P column (steel capillary 10 ft x 0.125 inch). The (1) in the aqueous phase was extracted into 5 mL of heptane and the extract analyzed by glc. The International Union of Pure and Applied Chemistry Leinonen, P. J.; Mackay, D.; Can. J. Chem.
