Abstract: This article conducts a comprehensive and in-depth introduction of the basic recrystallization operations commonly used in organic chemistry experiments, covering the principles of recrystallization, solvent selection, basic operation steps, and precautions. Through theoretical explanations and analysis of actual cases, the influence of various factors on the recrystallization effect is discussed in detail, aiming to provide a set of systematic, scientific and practical recrystallization operation standard guidelines for organic chemistry experiments, so as to achieve efficient and high-quality purification of organic compounds.

Key words: Organic chemistry experiment, Purification, Recrystallization, Operational standard
