    • PURPOSE: A synthetic method of 2,2'-dihydroxy-1,1'-binaphthyl-3-carboxylic acid is provided to reduce manufacturing period by simplifying manufacturing process and to reduce manufacturing cost by increasing production yield. CONSTITUTION: A synthetic method of 2,2'-dihydroxy-1,1'-binaphthyl-3-carboxylic acid comprises a step of manufacturing 2-hydroxynaphthalene, 3-hydroxy-2naphthalenecarboxylic acid with copper-amine composite to obtain 2,2'-dihydroxy-1,1'-binaphthyl-3-carboxylic acid. The copper-amine composite is selected from t-butyl amine, dibutyl amine, isopropyl amine, diethyl amine, pentyl amine, piperidine, morpholine, or a mixture thereof. The manufacturing method additionally comprises a step of cleaning and purifying the product by a chloride aqueous solution.
    • 目的:提供2,2'-二羟基-1,1'-联萘-3-羧酸的合成方法,通过简化制造工艺并通过提高产量来降低制造成本来缩短制造周期。 构成:2,2'-二羟基-1,1'-联萘-3-羧酸的合成方法包括用铜 - 胺复合物制备2-羟基萘,3-羟基-2-萘基羧酸得到2,2' - 二羟基-1,1'-联萘-3-甲酸。 铜胺复合物选自叔丁胺,二丁胺,异丙胺,二乙胺,戊胺,哌啶,吗啉或其混合物。 该制造方法还包括通过氯化物水溶液清洗和净化产物的步骤。
