高效液相色谱法对长链烷基芳烃的组分分析研究

Study on component analysis of long chain alkyl aromatic hydrocarbons by high performance liquid chromatography

烷基化芳烃作为第四代合成油系列产物,因其性能优异而受到广泛关注,其中长链烷基芳烃由于碳数较大、沸点较高而难以气化、相对成分较为复杂,给组分分析带来很大困难。利用高效液相色谱法对长链烷基芳烃的各组分进行了分析,分别探讨了紫外检测波长、流速以及流动相的极性等参数对色谱分析结果的影响,并总结出一种适于长链烷基芳烃组分分析的方法。研究结果可为分析长链烷基芳烃相关产品提供一定的理论指导。

Alkylated aromatic hydrocarbons,as the fourth generation synthetic oil series products,have received widespread attention in recent years due to their excellent performance.Among them,long⁃chain alkyl aromatic hydrocarbons pose great difficulties in component analysis due to their large carbon number,high boiling point,difficulty in gasification,and complex relative composition.In this study,high⁃performance liquid chromatography is employed to analyze the components of long⁃chain alkyl aromatic hydrocarbons,and explores the effects of parameters such as UV detection wavelength,flow rate,and solvent polarity on the chromatographic analysis results.A suitable method for the analysis of long⁃chain alkyl aromatic hydrocarbon components is summarized,and the study results can provide theoretical guidance for the analysis of long⁃chain alkyl aromatic hydrocarbon related products in the future.
