In Figure 2.2-3 the curves Ig are the vapour pressure curves of the pure components which end in a critical point l=g. The curves l=g, h=g and h=g are vapour-liquid critical curves and the curves h=h are curves on which two liquid phases become critical. The points of intersection of a critical curve with a three-phase curve hhg is a critical endpoint. Distinction can be made between upper critical endpoints (UCEP) and lower critical endpoints (LCEP). The UCEP is highest temperature of a three-phase curve, the LCEP is the lowest temperature of a three-phase curve. The point of intersection of the hhg curve with a l/=g curve is a critical endpoint in which the li liquid phase and the vapour phase are critical in the presence of a non-critical l2 phase (h+(h=g)) and the point of intersection of the hhg curve with a h=h curve is a critical endpoint in which the two liquid phases h and // are critical in the presence of a non-critical vapour phase (h=h)+g)-...

The total Pb and Li vapor pressure over 497 C Pb-Li liquid is shown in Figure 23 as a function of Pb concentration. The pressure above Pbg3Li] 7 (1.6 mPa or 1.2 x 10 Torr) is a factor of 50 lower than ideal and a factor of 270 lower... 

Figure 21. Ratio of actual to ideal Li partial pressure above Pb-Li liquids (yu) as a function of liquid temperature. Actual" refers to pressures inferred from electromotive force data, while ideal" is the product of the Li atom fraction and the vapor pressure of pure Li. At 500°C, the actual Li partial pressure above high-Pb eutectic liquid is a factor of 1400 lower than the ideal solution prediction.

A classical method using Na- or Li-liquid ammonia (Birch reduction conditions) is effective for reductive dehalogenations of aryl and vinylic halides, but it is not always successfully applied to alkyl halides, although cyclopropyl halides and bridgehead halogens are exceptions.Under such conditions, the reactions are often accompanied by side reactions, such as elimination, the Wurtz coupling reaction, cyclization and reduction of carbonyl compounds. An example, a synthesis of pentaprismane (1), is shown in Scheme 4. ...
