Introduction: A common problem encountered in chemistry involves the separation of a mixture of two or three compounds into single compound fractions followed by the purification and identification of each. To effect the separation, the chemist must make use of the different properties of the components. Differences in solubility, density, acid-base chemistry, and reactivity are used to ...

6. Liquid/Liquid Extraction - Penn State University

what is aptly called the "work-up" of the reaction mixture, that is, the separation and purification of the desired product from the mixture of by-products and residual starting material. Liquid/ liquid extraction is often used as the initial step in the work-up of a reaction, before final

The Extraction of Benzoic Acid from a Mixture

Extraction is one of the most common and often used techniques in organic chemistry. It is a common way of separating a desired compound from a mixture. The separation itself is usually based on polarity differences between the molecule you are interested in isolating and the other components of the mixture.
