有机提纯操作原则“不增、不减、简单、环保”。有机提纯原理依据有机物的水溶性、互溶性以及酸碱性等,可选择不同的分离方法达到分离、提纯的目的。有机提纯方法在进行分离操作时,通常根据有机物的沸点不同进行蒸馏或分馏;根据物质的溶解性不同,采取萃取、结晶或过滤的方法。 The principle of organic purification is “not increasing, decreasing, simple, and environmental protection”. The principle of organic purification is based on the water solubility, mutual solubility, and acidity and alkalinity of organic materials, and different separation methods can be selected for separation and purification purposes. In the organic purification method, distillation or fractionation is generally performed according to the boiling point of the organic substance when the separation operation is performed, and extraction, crystallization, or filtration is adopted depending on the solubility of the substance.
