Improvement of the Measurement of Saturated Vapor Pressure of Pure Liquids

School of Chemistry and Environmental Engineering, Sichuan University of Science & Engineering, Zigong 643000, Sichuan Province, P. R. China

Received Date: 27 August 2019

The measurement of saturated vapor pressure of pure liquid has been improved by designing a novel apparatus. The pure liquid vapor at phase equilibrium could be obtained, and the temperature of phase equilibrium could be accurately measured. In addition, the balance between the internal pressure and external pressure could been conveniently adjusted. The improved method is simple, rapid, easy operate, time-saving and safe.
- Saturated vapor pressure,
- U-shaped isobarometer,
- Isobaric control,
- Apparatus optimization
