摘　　要：醚类和醇类化合物是目前汽油产品中常用的两类含氧添加剂。根据含氧添加剂的不同,可以对成品汽油进行分类。红外光谱是分析汽油中醚类和醇类化合物的有效手段,并能根据分析结果对汽油进行种类识别。本文提出采用介电谱技术对加有不同含氧化合物的汽油进行识别,获得了与红外光谱相一致的结果。研究表明,介电谱技术能够获得汽油不同组成、结构的信息,为汽油的快速分析测试提供了一种新的技术,也为应用介电谱技术预测不同组成特征汽油的质量指标奠定了基础。Ether and alcohol compounds are two oxygenated additives commonly used in gasoline products. The gasoline products can be classified according to the difference of oxygenated additives. Infrared spectroscopy is an effective method for analyzing ether and alcohol compounds in gasolines and its analytical results can be used for indentifying the kinds of gasolines. This paper proposes using dielectric spectroscopy to identify gasolines added with oxygenated compounds and the new method has achieved same effect as infrared spectroscopy. The results show that the dielectric spectroscopy can obtain the composition and structure information of gasolines, providing a new technique for rapid analysis of gasoline porducts and a foundation for predicting quality indices of gasolines with different composition characteristics.
