How does solvent extraction work?
Solvent extraction is a method for separating compounds based on their relative solubilities in two immiscible liquids.
The process is often used to separate an organic product from a reaction mixture.
Suppose your product is in an aqueous reaction mixture with other substances.
You might pour the mixture onto a separatory funnel and shake it with some ether.
The organic product dissolves preferentially in the ether. When the layers separate, you draw off the lower aqueous layer.
The ether layer contains most of your product, and you can remove the ether by distillation.
The process involves a dynamic equilibrium.
Product(aq) ⇌ Product(in ether)
The product distributes or partitions itself between the two solvents according to the equation
