Standardized Operational Guidelines for Sublimation in Organic Chemistry Experiments
摘要
Abstract
Sublimation is an important technique for the separation and purification of solid substances,widely used in the refinement of natural products and synthetic compounds.Due to differences in experimental content,conditions,and procedural descriptions in textbooks,experimenters often encounter non-standardized operations during sublimation experiments,leading to insufficient product purity,reduced yields,significant deviations in experimental results,and even safety hazards.Based on experience in organic chemistry laboratory teaching and scientific research practice,this paper systematically analyzes the applicable scope and key operational points of both atmospheric and vacuum sublimation.Furthermore,standardized operational recommendations are proposed to ensure the safety,efficiency,and reproducibility of experiments,providing a valuable reference for researchers in the field.关键词
