摘　　要：以最具有代表性的有机胺单乙醇胺(MEA)水溶液为研究对象,研究了抗氧剂(M^(3+)Y)L对MEA溶液氧化降解的抑制作用。主要考察了CO_(2)酸气含量、氧气压力、抗氧剂量、MEA溶液浓度、反应温度等因素对氧化抑制作用的影响。结果表明,在反应温度为120℃、氧气压力为1.0 MPa、搅拌速度为400 r/min时,添加0.2%抗氧剂可使3 mol/L的MEA水溶液的抗氧化降解能力提高近16倍。此外,还对(M^(3+)Y)L氧化抑制作用失效的原因进行分析并提出了相应对策。Taking monoethanolamine(MEA)aqueous solution,the most typical organic amine,as the object,the inhibition effect of(M^(3+)Y)L antioxidant on the oxidative degradation of MEA is studied.The influences of MEA solution,CO_(2)acid gas content,oxygen pressure,anti-oxygen dosage,and reaction temperature,etc.are investigated.The results indicate that the antioxidant degradation ability of 3 mol·L^(-1)MEA aqueous solution can be increased by nearly 16 times when the reaction temperature is 120℃,oxygen pressure is 1.0 MPa,and the stirring speed is 400 r·min^(-1),and 0.2 wt%of antioxidant is added.In addition,the reasons for the invalid of oxidation inhibition of(M^(3+)Y)L are analyzed and the corresponding countermeasures are proposed.
