Abstract
The structure of vacuum pump oil base oil was explored.The experiments on infrared(MIR)spectroscopy in the structure of vacuum pump base oil(including one-dimensional MIR spectroscopy,second-order derivative MIR spectroscopy,fourth-order derivative MIR spectroscopy,and deconvolution MIR spectroscopy)was conducted.The results showed that the infrared absorption modes 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 components of vacuum pump oil base oil include mineral base oil,PAO base oil,and sebacic acid ester base oil,with PAO base oil having a slightly 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.
