CAS: 128-97-2
分子式: C14H8O8
分子量: 304.22
中文名称: 
1,4,5,8-萘四甲酸
英文名称: 
1,4,5,8-Naphthalenetetra carboxylic acid
1,4,5,8-naphthalenetetracarboxylic acid
1,4,5,8-naphthalenetetracarboxylic acid hydrate,
1,4,5,8-naphthalene tetraformic acid
1,4,5,8-naphthalenetetracarboxylic acid hydrate
性质描述: 白色结晶,从盐酸水溶液中得叶状或针状结晶。无特定熔点,若快速加热时在200-250℃则分解,若慢速加热,则在140-150℃生成1,4,5,8-萘四甲酸二酐([81-30-1])。稍溶于水和热乙酸,溶于丙酮水溶液,极微溶于苯、氯仿、二硫化碳和乙醇。
生产方法: 以芘为原料,经氯化、氧化可制得该品。用苊与丙二腈反应后再经氧化也可生成。另外,用苊在三氯化铝存在下与氨基甲酰氯或二甲氨基甲酰氯在氯苯中加热反应,经氨氧化钠溶液水解后生成5,6-苊二甲酸。然后,进行氧化反应也可制得1,4,5,8-萘四甲酸。
用途: 本品塑料工业用于制造具有良好绝缘性和抗放射性,并可耐高温(400℃以上)的新型树脂--聚酰亚胺及TNM聚合物。
