分子式:C22H10O2
分子量:306.32
CAS号:641-13-4
性质:从硝基苯中得到的橙色晶体,熔点为300℃。易溶于热苯和热硝基苯,微溶于乙醇、乙醚、乙酸和苯中,升华时有部分晶体分解。
制备方法:由1,8-萘内酰亚胺经水解、重氮、芳化、环合而得。1.水解水解锅内加入萘内酸亚胺及30%液碱,加水调整体积。加热至95-100℃,保温2h,冷至50℃,过滤,得1,8-氨基萘甲酸钠盐[129-02-2]。2.重氮向重氮桶加入盐酸、水冷至0-5℃,在1.5-2h加入1,8-氨基萘甲酸钠盐和亚硝酸钠的混合溶液。搅拌0.5h,用15%液碱中和到pH为3-4。得1,8-羧基苯胺重氮盐。3.芳化在重氮桶的上述物料内,加入氯化亚铜、小苏打和氨水,搅拌1h。加入硫化碱溶液脱铜,至渗圈为淡咖啡色为终点。滤去硫化铜,滤液以65%硫酸酸析至pH=4。过滤,洗涤,滤饼在80-90℃下干燥,得1,1'-联萘-8,8'二甲酸(基那酸)。4.环合在锅内先加20%发烟硫酸,冷却到20℃以下,加入基那酸,温度不超过33℃,搅拌反应2h即得产品。
