Simultaneous Distillation and Extraction

Simultaneous Distillation and Extraction (SDE) is a laboratory technique used to separate volatile compounds from a mixture while also extracting them. In this process, a sample is heated, causing its components to vaporize. The steam carries these compounds into a condenser, where they cool and revert to liquid form. At the same time, a solvent is used to dissolve other desired components, allowing both separation and extraction to occur together. This technique is commonly used in the production of essential oils and in the analysis of natural products, making it valuable in chemistry, food science, and fragrance industries.
