Dephlegmation is a term often used in chemistry to refer to the process of separating a liquid mixture by heating and condensation. However, there are several synonyms for this word that can be employed in different contexts. The term "distillation" is often used interchangeably with dephlegmation, as it refers to the same process of separating mixtures through heating and condensation. Another synonym that can be used is "rectification," which emphasizes the purification aspect of this process. "Fractionation" is another term that can be used when the goal is to separate a mixture into its component parts. Ultimately, whether one uses the term dephlegmation or its synonyms will depend on the specifics of the situation and the context in which the word is being used.
