Claims (1)
DMT용융조에서 DMT를 용융하기전이나 용융후에 DMT에 대하여 0.5몰-1.2몰의 EG를 투입하여 Pre-BHT를 제조함을 특징으로 하고, 이를 통상의 방법과 같이 DMT 계량조를 시킨다음 에스텔교환 반응관에서 에스텔교환반응시키는 비스-베타-하이드록시 에틸텔레프타레이트(BHT)의 제조방법.It is characterized in that Pre-BHT is prepared by injecting 0.5 mol-1.2 mol of EG to DMT before or after melting DMT in DMT melting tank. A method for producing bis-beta-hydroxy ethyl terephthalate (BHT) which is subjected to ester exchange reaction in a reaction tube.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
