CAS: 528-44-9
分子式: C9H6O6
分子量: 210.14
熔点: 231℃
中文名称: 
1,2,4-苯三羧酸
苯偏三酸
1,2,4-三羧基苯
1,2,4-苯三甲酸
偏苯三甲酸
英文名称: 
1,2,4-Benzene tricarboxylic acid
1,2,4-Benzenetricarboxylic acid
1,2,4-tricarboxybenzene
1,3,4-benzenetricarboxylic acid
1,4,5-benzenetricarboxylic acid
4-carboxyphthalic acid
trimellitic acid
性质描述: 白色结晶。熔点229-230℃(238℃)。易溶于乙醇和二甲基甲酰胺,溶于丙酮,略溶于水和乙酸乙酯,几乎不溶于苯、氯仿和二硫化碳。
生产方法: 以偏三甲苯(1,2,4-三甲苯)为原料,经硝酸氧化或高锰酸钾氧化或液相空气氧化而得。1.硝酸氧化法 第一步氧化:偏三甲苯与硝酸的摩尔比为1:2.16,硝酸浓度为17%,反应温度200℃,反应压力约3.9MPa以下。第二步氧化:偏三甲苯与硝酸的摩尔比为1:4.5,硝酸浓度为50%,反应温度180℃,反应压力约3.9MPa以下。反应所得偏苯三酸母液经冷却、结晶、离心、洗涤干燥成品。收率55%以上。2.高锰酸钾氧化法 以纯度为95%的偏三甲苯为原料,在20-30倍水存在下,于90-95℃温度下用高锰酸钾氧化,所得产物经酸化、重结晶、烘干,得白色针状结晶。
用途: 制备偏苯三甲酸酐、偏苯三甲酸酯,用于树脂、增塑剂、染料、胶粘剂等方面。
