100.0426 ± 0.00112.18
220.0526 ± 0.00162.68
 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 10, method. Dried air was passed through the vessel with a saturated solution of (2) in (10 and U-tubes with CaCl2,/sub> and next absorbed (2) was weighed.

 Source and Purity of Materials:
   (1) source not specified; b.p. 109.8°C at 752 mm Hg, d224 0.8636, d104 0.8743
   (2) not specified.
