Extraction, washing, and drying are fundamental components of organic chemistry laboratory. Proficiently mastering and applying extraction and washing techniques to separate and purify organic compounds is an essential experimental skill that chemistry undergraduates must acquire. Due to the lack of unified and clear operating standards, actual teaching and experimental processes may lead to deviations in results, reagent waste, and even safety incidents. This article provides basic operational guidelines and standard recommendations for extraction, washing, and subsequent drying experiments in organic chemistry, aiming to serve as a reference for domestic colleagues engaged in laboratory teaching and scientific research.
