Study On Degrade Waste PET And Use The Degradation Product To Prepare Surfactant

Waste plastic have been a global problem. It’s not only lead environment problem,but also waste resource. This paper focuses on waste PET, use catalyzer and ethyleneglycol (EG) to degradation it. After that we prepare two kinds of catalyzers, and testtheir catalyst capability. Then explore some method use the degradation product toprepare surfactant. This paper contains:1. Research PET degradation use electric jacket, and study factors affect BHET yield,include: temperature, reaction time, mole ratio, dosage of catalyst.2. Study on use doping method to prepare metallic oxide catalyzer, and we gain acatalyzer have more catalyst capability than zinc acetate, and we study different factorinfluence catalyst capability: kind of metal, metal mole ratio, aging time, agingtemperature, calcination temperature, calcination time.3. Use microwave to degrade PET plastic, and explore temperature, react time, moleratio, dosage of catalyzer and microwave power influence BHET yield.4. Sulfonate degradation product, use chlorosulfonic acid to sulfonate benzene ring,change molecular structure. We gain a foaminess well product. Then we measure thesurface tension and contact angle.5. Use agent solve degrade product, employ Ubbelohde viscometer measuremolecular weight before and after degradation. Use this data to analysis thecomposition of the product.6. Apply IR characteristic degradation product and self-make surfactant, HPLC toanalysis pureness, DSC to test degradation product.
