Abstract
본 발명은 직접 에스테르화법의 장치를 개량하여 복수개의 반응관을 사용하여 비스-β-하이드록시에틸테레프탈레이트의 저축합물을 제조하는 장치에 관한 것으로, 냉각수 입구(25), 냉각수 출구(26)가 설치된 정류탑(7)이 환류 라인(16)을 통해 환류액체류 포트(12)와 연결되어 있으며, 환류액체류 포트(12)는 각 반응조(3)(19)와 오버플로우 라인(14)(22)과 밸브(13)(23)로 연결되어 있음을 특징으로 한다.The present invention relates to an apparatus for producing a low-condensation product of bis-β-hydroxyethyl terephthalate using a plurality of reaction tubes by improving the apparatus of the direct esterification method. The installed rectification tower 7 is connected to the reflux liquid flow port 12 through the reflux line 16, the reflux liquid flow port 12 is each reactor (3) (19) and the overflow line (14) ( 22) and valves 13 and 23 are characterized in that the connection.
