具有光学活性的化学物质目前已在药物、食品、饮料、农药等领域得到了广泛的应用 ,需求日益增长 ,但化学合成的产物多为无活性的外消旋体 (混合物、化合物或固体溶液 ) ,要从中得到单一对映体必须进行拆分 ,非对映体盐结晶法是目前工业应用最广泛的一种拆分技术 ,其原理是采用 Optically active chemicals have been widely used in the fields of medicine, food, beverage, pesticide and the demand is increasing day by day. However, most of the products synthesized by chemical synthesis are inactive racemates (mixture, compound or solid solution) , To get a single enantiomer from which must be resolved, diastereomer salt crystallization method is currently the most widely used in industry, a split technology, the principle is to use
