Your liquids are immiscible.
You can separate two immiscible liquids using the method of fractional distillation if the 2 liquids are having an appreciable difference in their boiling points.
Immiscible liquids are liquids that don't dissolve in one another. Two examples of immiscible liquids would be alcohol and water and gasoline and water.

Almost any oil and water do not mix. Immiscible is the word
miscible
This place is called interface.
The most common method is the distillation; for immiscible liquids use a separatory funnel.
When a solid "mixes" with a liquid the solid can be termed soluble and will "dissolve" in said liquid (salt and water), if the solid does not dissolve it is termed insoluble (sand in a glass of water). When a liquid "mixes" with another liquid the two are classed as miscible, if the two liquids do not mix and form two separate layers, the liquids are classed as being immiscible
The liquids do not mix. They are said to be immiscible.
This funnel is used to separate two immiscible liquids by decantation.
