A process used to purify substances or to isolate them from other substances. In industrial applications, the ultimate goal is the isolation of a product of given purity. Most industrial chemical processes involve a separation stage. This may involve a preliminary purification stage before the reaction process, or a final stage involving the separation of the desired product.
