| 摘 要： | 用DB-624毛细管色谱柱分离了由甲醇和丁烯混合物反应所生成的甲基叔丁基醚(以下简写作MtBE)共存的杂质化合物,并用气相色谱-质谱联用法予以鉴别和测定。测定中采用峰面积归一化法,总共测得包括MtBE本身在内的66种化合物,并给出了它们的相对含量。并对其中部分杂质化合物的形成机理也作了探讨。

| Abstract: | The chemical compounds co-existed with methyl tert.-butyl ether(abbreviated as MtBE) which was synthesized by the reaction between methanol and mixture of butenes,were separated on DB-624 capillary chromatographic column,identified and determined by GC-MS.The peak area-normalization method was adopted in the determination.Totally,66 compounds(including MtBE itself) were found and their contents(in relative %) given.Formation mechanism of part of the co-existing components,present as impurities,was also disc... |
