Variables:
Temperature = One temperature: 25 °C
Prepared By:
A. Maczynski, Z. Maczynska, and A. Szafranski
Experimental Remarks:
The solubility of 1-hexene in water at 25 °C was reported to be 55.4 mg(1) dm

sln.
The corresponding mass percent and mole fraction,

Experimental Data:
(Notes on the Nomenclature)
Method/Apparatus/Procedure:
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 instruments equipped with a 15% SE-30 on 60/80 mesh acid-washed (CH3)
