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.
