Dimethylaniline is distilled with steam at 90 kPa to free it from the non-volatile impurities Assuming it to be completely immiscible with water, determine
(a) the distillation temperature
(b) The composition of the vapour produced.
The vapour pressure data follows:
T,K
343.2
374.8
Vap pressure aniline, kPa
1.333
5.332
Vap pressure water, kPa
31.19
106.91
Plot of ln(vap pressure) versus 1/T may be assumed linear.
