甲基丙烯酸甲酯中阻聚剂2,4-二甲基-6-叔丁基苯酚的测定

Determination of Polymerization Inhibitor 2,4-dimethyl-6-tertbtylphenol in Methyl α-methacrylate

提出用气相色谱外标法测定甲基丙烯酸甲酯中阻聚剂 2 ,4 -二甲基 - 6 -叔丁基苯酚的质量分数。在选定的色谱条件下 ,仪器均有良好的稳定性 ,且所测组分定量结果的重复性好。此方法较内标法简单、快捷。

The content of polymerization inhibiter 2,4-dimethyl-6-tertbtylphenol in methylα-methacrylate was determined by the external standard menthod of gas chromatography.Under the chosed chromatography condition, the stability of the apparatus was better and the quantitation results of the determined component had better repeatability. This method was easier and faster than the internal standard method.
