Notes:
   ^a  Critical point of solubility.

Method/Apparatus/Procedure:
   Solubility was measured by Alekseev's method. Nine solubility-temperature curves of constant alcohol-benzene ratio and another five curves of constant alcohol-water ratio were constructed. The method of phase equilibrium measurements was not reported. Critical points of solubility were obtained by Bachman², and Alekseev's¹ methods.

Source and Purity of Materials:
   (1) Source not specified; purified; b.p.=96.5°C at 750 Torr, d(30°C,4°C)=0.7956, n(25°C,D)=1.3837.
   (2) Source not specified; purified; b.p.=79.0°C, at 752.5 Torr, d(30°C,4°C)=0.8680, n(25°C,D)=1.4980.
   (3) Source not specified.

Estimated Errors:
   Solubility: Not reported.
   Temperature: Not reported.
