complete miscibility

In most such processes, acetone is first used to wash away all water, exploiting the complete miscibility of these two fluids.

That is called complete miscibility, but that is not what we focus on for paint stripping.

As shown in the diagram, this means that there is a temperature interval of complete miscibility, with partial miscibility at both higher and lower temperatures.

The miscibility gap tends to get wider with higher alkanes and the temperature for complete miscibility increases.

Argemone seeds find use as a substitute because of the easy availability, low cost and their complete miscibility of their oil with mustard oil.

However, sometimes higher pressures will be needed, such as extraction of vegetable oils, where pressures of 800 bar are sometimes required for complete miscibility of the two phases.

The ideal entropy of mixing of multiple pure compounds is always positive (the term -T ΔS is negative) and ΔG would be negative for all compositions, causing complete miscibility.

Complete miscibility occurs when the Gibbs free energy of mixing is less than the Gibbs free energies of the components, and the solution maintains its homogeneity only as long as ΔG M remains less than the Gibbs free energy of any two possible co-existing phases.
