【摘要】 本文讨论了制取电容级的癸二酸、对硝基苯甲酸、苯甲酸、月桂酸及其铵盐等的新工艺。其工艺条件为：在有机酸中加入１～３倍高纯水通氨至ｐＨ为８左右，溶液脱色过滤后冷却结晶析出有机酸的铵盐，再将此铵盐加适量水溶解后用高纯度甲酸酸化。更多还原

【Abstract】 In this paper, a new process of preparing capacitor purity sebacic acid, p nitrobenzoic acid, benzoic acid, lauric acid, and their ammonium salts was discussed. The process conditions are that 1～3 times of high pure water was added to the organic acids and the ammonia pH about 8. The ammonium salts of the organic acids were crystalijed out from the solution after it was decolorized and filtered. Then the salts were dissolved into proper amount of high pure water, and the solution formed was acidified by high purity formic acid.更多还原
