Original Measurements
Yeh, S-Y.; Peterson, R. E.; J. Pharm. Sci. 1964, 53, 822-4.
Variables:
Room Temp:
298.15 - 318.15
$\pu{K}$
Pressure:
101.325
$\pu{kPa}$
Prepared by:
Method/Apparatus/Procedure:
The method and apparatus used are described in [1] with two minor modifications: the mercury sealing cup was eliminated in the new version and the gas was presaturated with water vapor.
Source and Purity of Materials:
- Research grade Matheson Co. Minimum purity 99.7%.
- Redistilled from all glass still. Degassed.
Estimated Errors:
Ambient temperature: δT/K = ±0.05
Mass concentration (m/v) (1): δL = ±1% (authors)
Pressure: δP/mmHg = ±2
(δP/bar = ±0.003)
