Beschreibung
Zusammenfassung:	The present invention relates to a method for preparing hydrochloric acid from polyvinyl chloride and a method of treating waste polyvinyl chloride and, more specifically, to a method for preparing hydrochloric acid from polyvinyl chloride and a method of treating waste polyvinyl chloride by using metal oxide or carbon nitride catalysts in a liquid reaction condition. According to the present invention, dechlorination reaction of waste polyvinyl chloride can be effectively performed. 본 발명은 폴리염화비닐로부터 염산을 제조하는 방법 및 폐 폴리염화비닐의 처리방법에 관한 것으로, 더욱 상세하게는 액상의 반응조건에서 금속산화물 또는 카본 나이트라이드 촉매를 사용하여 폴리염화비닐로부터 염산을 제조하는 방법 및 폐 폴리염화비닐을 처리하는 방법에 관한 것이다.
