Nitrous oxide: Saturation properties and the phase diagram

“…On the other hand, the vapour pressure of nitrous oxide has been extensively and rigorously measured at the triple point. The values reported oscillate around those firstly determined in the laboratories of Giauque [5] and of Clusius [6]. We have taken as most reliable the measurements made in Oxford [10,11].…”

“…The phase diagram has been constructed. ; 4, reference [6]; 5, reference [7]; , reference [8]; , reference [9]; , reference [30]; e, reference [31]; Â, reference [34]; +, reference [37]; Ç, reference [39]; , reference [47,38,48,49]; , reference [52]; j, reference [53]; N, reference [54]; ., triple point, this work; d, critical point, this work. The solid, liquid and gaseous phases are represented by s, ', g, respectively.…”

Legend: the symbols are: s, reference [5]; 4, reference [6]; 5, reference [7]; , reference [30]; , reference [8]; e, reference [31]; +, reference [37]; N, reference [10,11]; Ç, reference [12,13]; h, reference [14]; Â, reference [34]; , reference [15,16]; , reference [17][18][19][20]; , reference [21][22][23]; , reference [24][25][26][27]; , reference [38]; ., triple point, this work; d, critical point, this work. These results are of little use in extrapolating to the far temperature region in which we are interested for the present calculations, viz.…”

Thermodynamic properties of the system methane + carbon monoxide at 90·67° K

“…The purity of both gases was repeatedly tested by measuring the constancy of the triple-point pressure during melting. For these measurements the apparatus described by Clusius and Staveley 19 was used with a manometer similar to that described by Lambert and Phillips,20 with which pressures could be read to 0.01 mm. With neither substance was there any significant trend in the triple-point pressure as a crystalline sample melted.…”
