Glass Ball as Bullet Solubility System: cis-1,2-Diiodoethene (cis-1,2-diiodoethylene) with Water.
Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) cis-1,2-Diiodoethene (cis-1,2-diiodoethylene); C2H2I2; [590-26-1]  NIST Chemistry WebBook for detail
Original Measurements:
   Andrews, L.J.; Keefer, R.M., J. Am. Chem. Soc. 1951, 73, 5733-6.

 Variables:
   Temperature = 298 K

t/°CConcentration c1 [mol m**-3]102 * Mass Fraction w1 (compiler) 105 * Mole Fraction x1 (compiler)
25.01.654.63 x 10-22.98
 Method/Apparatus/Procedure:
   Water was mixed with cis-1,2-diiodoethene in a glass stoppered Erlenmeyer flask which was then placed in a constant temperature bath and rotated for 30 hours. The organic halide content of the aqueous phase was extracted with n-hexane. The  optical density of the extract was measured against a blank pure n-hexane sample using a Beckman spectrophotometer as described elsewhere.1

 Source and Purity of Materials:
   (1) Prepared by isomerization of crude trans-1,2-diiodoethylene at 160 °C. The cis- and trans-isomers were separated by filtration and then centrifugation.
   (2) Distilled (compiler).

 Estimated Errors:
   Solubility: Not specified.
   Temperature: ± 0.3 K (compiler).
