Consider a ternary mixture composed of water, -propanol, and acetone at
. This Demonstration plots the residue curve map (RCM) for this mixture. There are two distillation regions separated by a distillation boundary (shown in red) running from pure acetone to the only azeotrope in the ternary system (i.e., the binary azeotrope between water and
-propanol shown in red).
