Question

Using the phase diagram below of simple distillation: determine boiling point of an 80 mL:20 mL solution of cyclohexane:toluene, mol % composition of the initial distillate, and the number of simple distillations it will take to completely separate this mixture. (Important info: cyclohexane MW=84g/mol, d=0.78g/mL, bp=82°C; toluene MW=92 g/mol, d=0.87g/mL, bp=111°C.)

110 100 F 90 800 100 Cycl 80 0% Tol 20 Vapor Liquid 40 60 40 60 Mole percent cyclohexane Mole percent toluene 110 100 90 20 Cycl 0% Tol. 100% 80

Explanation / Answer

Ans.

i hope it will help you

The boiling point for the mixture is 83o C

the initial composition of distillate is 100% of cyclohexane

one simple distillation is enough as the solutions differ by 40o C in their boiling points.
