1-丁烯中微量甲基叔丁基醚和甲醇含量的测定方法改进

Improvement of Determination Method of Trace Methyl Tert - butyl Ether and Methanol for 1-Butene

根据测定1-丁烯中微量甲基叔丁基醚和甲醇的分析方法中存在的问题,分别对进样方式、毛细管色谱柱和仪器操作条件作了改进,建立了一次进样便可同时检测甲基叔丁基醚和甲醇的气相色谱法。改进后的方法操作简便,分离效果及重复性良好。

According to the question of measuring trace methyl tert-butyl ether and methanol for 1-butene,injection way,capillary column and apparatus operating conditions are improved. A gas chromatographic method? is established for the simultaneous determination of methyl tert-butyl ether and methanol in once injection. The method after improvement is operated simply. Separation effect and repeatability are good.
