Normal distillation reaction is a term commonly used in chemistry to describe the process of separating liquids with different boiling points. However, there are several synonyms that can be used to describe this procedure effectively. One such synonym is fractional distillation, which is used when the liquids have only a small difference in boiling points. Another similar term is rectification, which is used when purifying a substance with multiple volatile components. Finally, simple distillation is used when the liquids being separated have a significant difference in boiling points. Regardless of the term used, these processes are essential in chemistry and are widely used in various industries to produce high-quality products.
