t/°C102 * Mass Fraction w1 (compiler) 103 * Mole Fraction x1 (compiler)102 * w1/M1 [mol g**-1]
254.56 x 10-22.692.53 x 10-3
 Method/Apparatus/Procedure:
   A 1 to 15 volume ratio mixture of water and 1-chloropentane was introduced into an equilibration flask and then lowered into the waterbath thermostat. The assembly was shaken mechanically for about 90 minutes at  a constant temperature. The amount of water in the organic phase was determined by a modified Karl Fischer titration. The determination was done in triplicate. The description of procedure was taken from a  secondary source.1 The original university report is no longer available.

 Source and Purity of Materials:
   (1) Distilled.
   (2) Source not given. Purified and dried before use.

 Estimated Errors:
   Solubility: ± 2.5 %.
   Temperature: ± 0.05 K.
