220.0662 ± 0.00082.86
 Method/Apparatus/Procedure:
   The solubility of (1) in (2) was determined by titration. The solubility of (2) in (1) was determined by Clifford's (ref 1), method. Dried air was passed through the vessel with a saturated solution of (2) in (1) and U-tubes with CaCl2 and next the absorbed (2) was weighed.

 Source and Purity of Materials:
   (1) source not specified; b.p. 79.8°c at 740 mm Hg, d422 0.8768, d410 0.8887.
   (2) not specified.

 Estimated Errors:
