Title: Economically attractive technologies for plastic recycling

Abstract

This paper describes experiments investigating the depolymerization of polyethylene terephthalate (PET). Hydrolysis, glycolysis, and methanolysis reactions were studied. The use of the crude monomer to produce the plasticizer dioctyl terephthalate (DOTP) was also examined. Hydrolysis produced a terephthalic acid unsuitable for plasticizer. The glycolysis reaction product, bis(2-hydroxyethyl terphthalate), might be suitable without further purification for producing elastomeric copolyester. Three differently prepared products of the methanolysis reaction were use in plasticizer production. Economic analysis indicates the cost of recovered dimethyl terephthalate to be on the order of 60% of $800 per metric ton. 7 refs., 2 figs., 1 tab.
