Keywords: - epoxy, microwave, infrared spectroscopy, Nuclear magnetic resonance spectroscopy.



Abstract: - Fully cured epoxy samples of Araldite DLS 772 / 4 4' DDS with an amine to epoxy ratio of 0.8M were dissolved in 4M nitric acid in a microwave reaction system at a temperature of 120oC for a total of 75 minutes. The dissolved compound was collected and dried. High Performance Liquid Chromatography was used to analyze and separate the components in the compound. Infrared spectroscopy, nuclear magnetic resonance spectroscopy and electrospray ionization mass spectrometry was used to identify the dissolved product. The dissolved product was identified as 1, 3 - di(ethyl ester)-5-(diethyl amino)-2-hydroxybenzene.
