摘　　要：采用中红外(MIR)光谱技术(包括一维MIR光谱、二阶导数MIR光谱、四阶导数MIR光谱和去卷积MIR光谱)开展多聚甲醛结构的研究。实验发现,多聚甲醛的主要红外吸收官能团包括νasCH2-多聚甲醛、νsCH2-多聚甲醛、δCH2-多聚甲醛和νC-O-多聚甲醛等。研究发现,采用MIR光谱可以快速鉴别多聚甲醛结构。本课题为多聚甲醛结构研究建立了一个新的方法学,具有重要的应用研究价值。The structure of paraformaldehyde was studied by mid-infrared(MIR) spectroscopy including one-dimensional MIR spectroscopy, second derivative MIR spectroscopy, fourth derivative MIR spectroscopy and deconvolution MIR spectroscopy. It was found that the main infrared absorption functional groups of paraformaldehyde included νas CH2-paraformaldehyde,νs CH2-paraformaldehyde, δCH2-paraformaldehydeand νC-O-paraformaldehyde. It was found that the structure of paraformaldehyde could be identified by MIR spectroscopy. A new methodology has be established for the study of paraformaldehyde structure, which has important application research value.
