 Method/Apparatus/Procedure:
   In a thermostatted glass-stoppered flask 10-25 mL (1) was shaken for min 4 hours with titrated water (a few mL of HTO equivalent to ca. 2 mCi/mL) and decanted. A 5-mL aliquot was reshaken for 4 hrs with 5 mL H2O in a 10-mL flask, sampled and assayed with a Nuclear Enterprises type 8301 liquid scintillation counter. The two-stage process eliminates quenching effects (due to solvent) on the scintillator.

 Source and Purity of Materials:
   (1) "Analar" grade repurified by conventional methods ref 1.
   (2) not specified.

 Estimated Errors:
   Solubility: 5% ± 1% (average deviation)
