스티렌계 모노머-함유 폴리머의 해중합 및 스티렌계 모노머의 회수를 위한 공정

본 발명은 스티렌-함유 폴리머 폐기물로부터 정제된 스티렌계 모노머, 예컨대, 스티렌을 제공하는 개선된 공정에 관한 것이다. 스티렌-함유 폐기물은 적합한 반응기에서 해중합되고, 해중합 생성물이 3-단계 증류 공정에서 응축되고 분리된다. The invention relates to an improved process for providing purified styrenic monomers, such as styrene, from styrene-containing polymer waste. Styrene-containing waste i...

Zusammenfassung:	본 발명은 스티렌-함유 폴리머 폐기물로부터 정제된 스티렌계 모노머, 예컨대, 스티렌을 제공하는 개선된 공정에 관한 것이다. 스티렌-함유 폐기물은 적합한 반응기에서 해중합되고, 해중합 생성물이 3-단계 증류 공정에서 응축되고 분리된다. The invention relates to an improved process for providing purified styrenic monomers, such as styrene, from styrene-containing polymer waste. Styrene-containing waste is depolymerized in a suitable reactor, and the depolymerization products are condensed and separated in a three-step distillation process.
