Organic chem distillation lab
Step by step set-up of a simple distillation in an organic chemistry lab. Winthrop university organic chemistry lab distillation and gas chromatography introduction distillation is a technique often used to purify a liquid or to separate liquid components of a mixture essentially, it is the process of converting a liquid (called the distilland) to vapor by heating it to the boiling. Typically, using simple distillation is preferrable because the apparatus is, well, simpler, and a simple distillation typically goes faster than a fractional distillation (and requires less energy) on the other hand, fractional distillation gives better separation between the liquids.
