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ν■、ν■、δ■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 ν■, ν■, δ■ and 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.
