무촉매 메탄올 분해에 의한 Poly(ethylene terephthalate)의 재활용에 관한 연구
Recycling of Poly(ethylene terephthalate) via Methanolysis without Catalyst
초록
Poly(ethylene terephthalate)의 재활용을 위하여 촉매가 없는 상태에서 고온, 고압에서의 메탄올 분해에 의한 dimethyl terephthalate와 ethylene glycol의 회수에 관한 연구가 진행되었다. 과량의 메탄올 존재 하에서 반응기를 62기압, 310 ℃에서 약 50분간 반응시키면 98% 이상의 높은 수율의 dimethyl terephthalate가 얻어져 기존의 방법보다 간편하며 경제적인 방법으로 재활용의 새로운 방법으로 제안되었다.
In order to recycle poly(ethylene terephthalate), methanolysis has been investigated at elevated temperature and under high pressure without catalyst to afford dimethyl terephthalate and ethylene glycol. The reaction was carried out under 62 atm, 310 ℃ for 50min to obtain 98% dimethyl terephthalate. The method has been suggested as a simple and economical one to recycle the poly(ethylene terephthalate).
