WebJul 9, 2024 · Azeotropic distillation is a special type of distillation for separating components of azeotropic mixtures by adding an entrainer that changes the relative volatility of the substances. Also called constant boiling mixtures, azeotropes have the same vapor and liquid concentration — which means no one component is more volatile than the other. WebFor example, “neat” HFC-43-10 and “neat” nPB are not azeotropes because there’s nothing else in it but one type of molecule. This is called a “monosolvent.” Now, oil and vinegar are a mixture of two fluids, but they’re don’t make an azeotrope because the fluids separate from each other, almost instantly. Same with oil and water.
