摘要
本文利用薄层色谱、包质联用、红外、核磁等手段对进口的共聚甲醛中添加的抗氧剂进行结构分析,确定它们的化学结构式如下:
Polyoxymethlene is a kind of current engineering plastic which has a wide usage.Toanalyze antioxidant in it is a very complex and careful piece of work. It is important forhuman to develop and research new variety of polyoxymethlene and antioxidant. By selecting a suitable way and solvent we have almost completely separatedantioxidant from polyoxymethlene. We made full use of Nuclear Magnetic Resonance which possessed the advantagesof plentiful information and meticulous structure, combining Infrared Spectrometer andMass Spectrometer, adopted Proton homonuclear decoupling, Off-Resonance Decoupl-ing, modern technique-Disturtionless Enhancement by Polarization Transfer (DEPT)and general ~1H NMR, ^(13)C NMR techniques, successfully determined the structure ofthese two antioxidants. The structure of antioxidant in polyoxymethlene as following:
