- 摘要：探索了真空泵油基础油结构。开展了真空泵油基础油结构中红外（MIR）光谱（包括：一维MIR光谱、二阶导数MIR光谱、四阶导数MIR光谱和退卷积MIR光谱）实验。结果发现，真空泵油基础油结构的红外吸收模式主要包括：νasCH3-真空泵油基础油、νasCH2-真空泵油基础油、νsCH3-真空泵油基础油、νaCH2-真空泵油基础油、νC=O-真空泵油基础油、δCH2-真空泵油基础油、δasCH3-真空泵油基础油、δsCH3-真空泵油基础油、β=C-H-真空泵油基础油、νC=O-O-1-真空泵油基础油、νC=O-O-2-真空泵油基础油、νC-C-真空泵油基础油、γ=C-H-真空泵油基础油和 ρCH2-真空泵油基础油。真空泵油基础油成分主要包括：矿物基础油、PAO基础油和癸二酸酯类基础油，其中PAO基础油的含量略高，而癸二酸酯类基础油的含量略低。MIR光谱可以快速开展真空泵油基础油结构研究。Abstract: The structure of vacuum pump oil base oil was explored. The experiments on infrared (MIR) spectroscopy in the structureof vacuum pump base oil (including one-dimensional MIR spectroscopy, second-order derivative MIR spectroscopy, fourth-orderderivative MIR spectroscopy, and deconvolution MIR spectroscopy) was conducted. The results showed that the infrared absorptionmodes of the vacuum pump oil base oil structure mainly include: νasCH3- vacuum pump oil base oil, νasCH2-vacuum pump oil base oil, νsCH3-vacuum pump oil base oil,νsCH2-vacuum pump oil base oil, νC=O-vacuum pump oil base oil, δCH2-vacuum pump oil base oil, δasCH3-vacuum pump oil base oil, δsCH3-vacuum pump oil base oil, β=C-H vacuum pump oil base oil,νC=O-1-vacuum pump oil base oil, νC=O-O-2-vacuum pump oil base oil, νC-C-vacuum pump oil base oil, γ=C-H-vacuum pump oil base oil, and ρCH2-vacuum pump oil base oil. The main componentsof vacuum pump oil base oil include mineral base oil, PAO base oil, and sebacic acid ester base oil, with PAO base oil having aslightly higher content and sebacic acid ester base oil having a slightly lower content. MIR spectroscopy can quickly conduct struc⁃tural research on vacuum pump oil base oil.
