Andrzej Maczynski, Z. Maczynska Solubility, Solubility data series A mixture of (1) and (2) was rotated for twenty hours in a constant temperature bath at 25 °C. A sample (5 - 20 mL) of the aqueous phase was withdrawn and extracted with a measured volume of hexane (10 - 50 mL) by shaking in a glass-stoppered Erlenmeyer flask. Next, the absorbance of the hexane phase was measured against a hexane blank on the Beckman spectrophotometer. The International Union of Pure and Applied Chemistry Andrews, L. J.; Keefer, R. M.; J.
