163. Based on the given data, construct a boiling diagram for the system chloroform (CHCl3) - acetone (C3H6O) in the coordinates "temperature-composition" at p=const.
N
p/p Composition
liquid
solution ω (С3НbО), % Temperature
boiling
solution, t°C Condensate composition
(first portion of steam)
co (C3HbO), %
1 0 61.3 0
2 20 62.0 2
3 40 63.5 10
4 60 62.2 67
5 80 59.9 83
6 90 58.3 94
7 100 56.5 100

Using the boiling diagram and making the appropriate constructions, determine:
1. Type of deviation from Raoult´s law for the chloroform-acetone system. Justify the answer.
2. Boiling temperature and composition of the first portion of vapor for liquid of bulk composition ω(C3HbO) = 50%.
3. Composition of equilibrium vapor and liquid, if the liquid of gross composition ω(C3HbO) = 50% is heated to a temperature of 0.5°C above the initial boiling point.
4. The mass of distillate obtained at this temperature from 10 kg of liquid with ω(C3HbO) = 50%.
5. What will be the final result of distillation under optimal conditions of the CHCl3-C3HbO system with ω(C3HbO) = 15%? (Indicate the composition of the residue and distillate).
