Measurements of the vapor-liquid relationship for E.H.P.-mT.C.P. system are performed by use of an agitator vessel at three residual pressures (3.5 × 10-3 mmHg, 1.0 ×10-1 mmHg and 3.5×10-1 mmHg) and two liquid surface temperatures (130°C and 160°C). Independent of residual air pressure, at liquid surface temperature of 130°C this system is regarded as an ideal solution. But at liquid surface temperature of 160°C, the deviation from ideal behavior increases as the residual air pressure is lowered.
