Glass Ball as Bullet Solubility System: Cyclohexene with Water
Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Cyclohexene; C6H10; [110-83-8]  NIST Chemistry WebBook for detail
Original Measurements:
   Natarajan, G.S.; Venkatachalam, K.A., J. Chem. Eng. Data 1972, 17, 328-9.

 Variables:
   Temperature = One temperature: 30 °C

 Prepared By:
   M.C. Haulait-Pirson, G.T. Hefter

 Experimental Remarks:
   The solubility of cyclohexene in water was reported to be 4.950 x 10-3 mol L-1 at 30°C.a Assuming a solution density of 1.00 g mL-1 the corresponding mass percent and mole fraction (x1) solubilities calculated by the compilers are respectively, 0.0406 g(1)/100 g sln and 8.91 x 10-5.

Solubility data are also presented as a function of temperature in various salt solutions.

 Experimental Data:   (Notes on the Nomenclature)
   Notes:
   Table 1  a  It should be noted that although the authors state that the solubility refers to "water" the context in the paper is ambiguous and the data were probably obtained in 0.001 mol L-1 HNO3 solution.

 Method/Apparatus/Procedure:
   15 mL of the aqeous medium was equilibrated with 1 mL of (1) by mechanical shaking in a thermostatted glass burette. After settling (judged visually), 5 mL of the aqueous layer was withdrawn and the olefin content determined by titration with bromine using standard procedures.

 Source and Purity of Materials:
   (1) Prepared by dehydration of cyclohexanol and then washed, dried and fractioned. Purity (no specification) was determined by chromatography.
   (2) not specified.

 Estimated Errors:
   Solubility: not specified.
   Temperature: ± 0.05 K
