A New Instrument for Testing Saturated Vapour Pressure of Liquids

CHEN Li-li~a,OUYANG Jing~b,TANG Ai-dong~a(a.School of Chemistry and Chemical Eng.;b.Dept.of Inorganic Materials,School of Resources Processing and Bioengineering,Central South Univ.,Changsha 410083,China)  
The idea and project of a brand-new design for vapor pressure and average gasification enthalpy testing instrument were described.The instrument was introduced to determine saturated vapor pressure of water,from which average molar gasification enthalpy and entropy of water were deduced under different temperature from 60~100℃.The results indicate that the high precision,stable running and safety in operation can be offered by the new instrument.
