VAPOR LIQUID LIQUID LOCUS OF THE SYSTEM NITROUS-OXIDE PLUS WATER

This paper presents an investigation of the vapor-liquid-liquid locus of the system nitrous oxide + water. The locus extends from a vapor-li quid-liquid-hydrate quadruple point (12.5-degrees-C and 4.33 MPa) to a three-phase critical end point (36.6-degrees-C and 7.25 MPa). New exp erimental values for the pressure and temperature along the three-phas e locus were obtained, and a comparison was made with a model develope d for correlating the solubility of N2O in water. The agreement betwee n the experiment and the prediction is excellent.
