Use of separating funnel

   
Question from rose
"mr.tan what are the other liquids that can be separate in separating funnel eccept to water, oil, etc."

There is not direct answer to your question. 
The separating funnel works for mixture of liquids that do not mix together and have different densities.

Based on this principle,  you can separate any two or more liquids provided they do not mix together.
One example already given by you, water and oil.

Can you think of any other liquids that do not mix together?
Can thinner and water mix together?
