301.240.1248.35
 Method/Apparatus/Procedure:
   An excess of diiodomethane in 500 g water was shaken for 12 hours in a thermostat bath. Samples were then withdrawn and read against water in an interferometer made by Zeiss (ref. 1). A detailed description of the complete method and procedure is given in a  Ph. D. thesis (ref. 2).

 Source and Purity of Materials:
   (1) Eastman Kodak Co., shaken with Na2S2O3 solution. washed with distilled water, dried, and fractionally frozen twice before use.
   (2) Distilled.

 Estimated Errors:
   Solubility: ± 2.0 %.
   Temperature: ± 0.02 K.
