文章介绍我院傅立叶变换红外光谱仪在成品油添加剂剖析中新的应用,并且详细阐述分析谱图的过程。对成品油添加剂进行定性分析,得出主要官能团及组分,确定添加剂结构,对研究添加剂作用机理提供重要的指导意义,并且也鉴定出了添加剂的纯与不纯。本方法具有制样简单、快速、准确等特点。 This article introduces the new application of FTIR spectrometer in the analysis of refined oil additives and elaborates the process of analyzing the spectrum. Qualitative analysis of refined oil additives to obtain the main functional groups and components to determine the structure of additives to study the mechanism of additives provide an important guiding significance, and also identified the pure and impure of additives. The method has the characteristics of simple, fast and accurate sample preparation.
