How can water, methanol, and propanone be separated from each other?
Methanol and propanol can also form azeotropes, making separation difficult using conventional distillation methods. If both the water and methanol contents in the mixture are low, permeate gasification membrane separation can be considered; this method allows water and methanol, which have relatively small molecular diameters, to pass through the membrane, thereby achieving separation – depending on whether a suitable membrane with a pore size of around 0.5 nm can be found.
