Original Measurements
Hill, A. E.; J. Am. Chem. Soc. 1923, 45, 1143-55
Variables:
Ambient temperature: 5.4 - 69.5 °C
Prepared by:
Method/Apparatus/Procedure:
A mixture of (1) and (2) was mechanically stirred at various temperatures and, after saturation was obtained, was transferred to small cylinders, treated with weighed amounts of silver perchlorate and the solubility of the salt in the mixed solvent determined at 25 °C. After a correction for the amount of (1) present in the solid phase, the original (2) content of the saturated solution could be determined from the reference curve.
Source and Purity of Materials:
- source not specified; purified by recrystallization; dried over calcium chloride and finally over bright sodium wire; m.p. 54°C or higher.
- not specified.
Estimated Errors:
Ambient temperature: not specified.
