Measurement and characterization of PET degraded by glycerol
Source abstract
Abstract
The degradation of the waste polyester(PET) in glycerol was studied,and the degraded product was characterized using the infrared spectroscopy,ultraviolet spectroscopy(UV),mass spectrometry(MS),high performance liquid chromatography(HPLC) and thermal gravimetric analysis(TGA).The structure of the degraded product was determined by infrared spectroscopy and ultraviolet spectroscopy;the molecular structure and relative molecular weight were revealed via MS technology;and quantitative analysis of the product was conducted using HPLC and in combination with TGA,and its purity was determined.Finally,the epoxy value of the degraded product was determined by hydrochloric acid-acetone analysis,which was 0.259.
