以二胺类化合物作催化添加剂生产芳香羧酸的方法
摘要：
以二胺类化合物作催化添加剂生产芳香羧酸的方法：a.以脂肪族羧酸为溶剂，采用含氧分子的气体氧化烷基芳香烃或其部分氧化中间的产物直接得到芳香族羧酸产品；b.采用催化体系为钴－锰－溴－二胺四元复合体系，形成高效的钴－锰－溴－二胺四元复合催化体系。所述的二胺类催化活化剂是包含双氨基的烃类衍生物，包括脂肪二胺类化合物、芳香二胺类化合物以及二胺类化合物相应的铵盐。其中Co/Mn的摩尔比为0.1～100，Br/(Co+Mn)为0.1～10；钴的浓度为溶剂重量的50～10,000ppm。本发明可加速氧化过程；降低燃烧副反应；降低杂质；有效防止设备的过渡腐蚀；降低能耗和物耗。
摘要（英）：

The process of producing aromatic carboxylic acid with diamine compound as catalyst additive includes 1. obtaining aromatic carboxylic acid product directly in aliphatic carboxylic acid as solvent with gaseous alkyl arene oxide containing oxygen molecule or its partially oxidized intermediate product; and 2. adopting high efficiency quaternary composite Co-Mn-Br-diamine catalyst system. The diamine catalyst activator includes diamino hydrocarbon derivative, aliphatic diamine compound, aromatic diamine compound and ammonium salt of diamine compound. The quaternary composite Co-Mn-Br-diamine catalyst system has Co/Mn molar ratio of 0.1-100, Br/(Co+Mn) molar ratio of 0.1-10 and Co concentration in 50-10,000 ppm of solvent weight. The present invention has accelerated oxidation course, lowered combustion side reaction, less impurity, less corrosion to the apparatus and lowered power consumption and material consumption.
