进口甲基丙烯酸甲酯中阻聚剂快速测定方法及其作用机理研究

Rapid Determination of Inhibitor in Imported Methyl Methacrylate

建立了气相色谱法和高效液相色谱法快速测定甲基丙烯酸甲酯(MMA)中阻聚剂。气相色谱采用HP-INNOWAX色谱柱分离样品中杂质,液相色谱采用XDB-C18柱同时配置XDB-C18保护柱,直接对样品进行分析。结果表明,气相色谱法和高效液相色谱法均具有线性关系好、回收率高等优点,方法的相对标准偏差(RSD)分别为0.53%～3.6%和0.38%～2.8%。可满足进口MMA中阻聚剂测定的需要。

Gas chromatography and liquid chromatography were applied to determine inhibitor in imported methyl methacrylate, which showed good linear range and recoveries respectively. The methods meet the needs for determination of inhibitor in imported methyl methacrylate, and would produce economic and social benifit as well.
