Chopade and co-workers in 2003 reported the vapor–liquid, liquid–liquid, and vapor–liquid–liquid equilibrium for the system 2-methyl-1, 3 dioxolane (1) + water (2) system at 1 atm. They abbreviate the name of the former substance by “2MD.” They show the experimental data as symbols and model results (here, UNIQUAC) with the solid curves. Answer the fol lowing questions that are based on Figure E13-7:

Figure E13-7.

A. What is the normal boiling point of 2MD? 

B. At what temperature does the VLLE occur at 1 atm and what are the equilibrium compositions for VLLE? 

C. For a 20% by mole 2MD system, what are the equilibrium phases (and their composition) that exist at 1 atm and the following temperatures: 

a. 380 K 

b. 360 K

c. 340 Kfv
