Recycling of waste poly(ethylene terephthalate) with castor oil using microwave heating

Popis výsledku v původním jazyce

The chemical recycling of waste poly(ethylene terephthalate) (PET) using castor oil (CO) as a reagent is reported. CO presents a renewable alternative to petrochemical based reagents, e.g. glycols, and enables also substantial modification of final physico-chemical properties of a received product. Advantageously, microwave irradiation was used to accelerate the depolymerization of PET. A composition of obtained product was strongly influenced by the reaction temperature. When the decomposition of PET was performed at temperature higher than 240 degrees C, then a significant extent of side products based on PET oligomers and transesterified CO was observed due to dehydration and hydrolysis of CO. Contrary to that, PET decomposition took place at slow rate below 230 degrees C and the optimal reaction temperature lies in the relatively narrow interval from 230 degrees C to 240 degrees C. The product prepared in the optimal temperature range did not contain any high molecular weight PET o
