Variables:
Room Temp: 10 - 50 °C

Method/Apparatus/Procedure:
The organic phase was first saturated by shaking with water in a flask at a high temperature and then allowing the flask to cool in a thermostat to the desired temperature, with the resulting separation of excess water. After one day or more the solution was allowed to react with added calcium hydride in dry solvent. Hydrogen was evolved and the gas volume was read.
Source and Purity of Materials:
- Source not specified; purified by keeping over mercury, refluxing with phosphorous pentoxide and fractionating; BP = 110.4-110.6°C (760 torr).
- not specified.
Estimated Errors:
Ambient temperature: Not specified.
Components:
- Toluene, $\ce{ C7H8 }$; [108-88-3] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
