   The 1,3-dichlorobenzene was mixed with water in a sealed flask (1) with the aid of a magnetic stirrer for 48 hours in a water bath at constant temperature. After the solution was filtered through a glass-wool plug, the solute was extracted with 2, 2, 4-trimethylpentene. The optical density of each sample was determined spectrophotometrically (2). Mean and standard deviations were calculated from three measurements.
