   Water was mixed with diiodomethanme 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 solution was extracted with n-hexane. The optical density of the extract was  measured against a nhexane blank using a Beckman spectrophotometer (ref. 1).

Source and Purity of Materials:
   (1) Prepared from iodoform at the University of California; b. p. = 71.0 - 71.5 oC at 18 mmHg.
   (2) Distilled (compiler).

Estimated Errors:
   Solubility: Not specified.
   Temperature: ± 0.5 K (compiler).
