Abstract
DC60 กระบวนการตามที่เปิดเผยไว้เกี่ยวข้องกับการคืนสภาพตัวเร่งปฏิกิริยาชนิดโลหะจากกระแส สารจากการชะล้างตัวออกซิไดซ์ที่ได้ในการสังเคราะห์กรดคาร์บอกซิลิกโดยที่ตามแบบฉบับแล้วคือ กรดเทเรฟธาลิก นอกจากนั้นแล้วกระบวนการยังรวมไปถึงการเติมสารละลายสำหรับชะล้างลงสู่ สารกระจายตัวขณะหลอมเหลวที่อุณภูมิสูงเพื่อคืนสภาพตัวเร่งปฏิกิริยาชนิดโลหะและต่อจากนั้นเป็น การดำเนินการกับของผสมเอเควียสหรือของผสมเอเควียสที่บริสุทธิ์ ดังนั้นจึงเป็นการสกัดเพียงหนึ่ง ขั้นตอนเพื่อขจัดสารเจือปนชนิดอินทรีย์ให้ได้เป็นกระแสสารสำหรับสกัดและรูปกระแสน้ำมันส่วนเกิน ซึ่งประกอบด้วยตัวเร่งปฏิกิริยาชนิดโลหะ DC60 The process, as disclosed, involves the recovery of a metallic catalyst from the current. Oxidizing agents obtained in the synthesis of carboxylic acids, which are typical Terephthalic acid In addition, the process also includes adding a leaching solution to the Dispersant at high temperature melting to recover metal catalyst and then to Processing with pure acacia mixtures or pure aquarius mixtures. So it is just one extraction. A step to remove organic impurities into a stream, extraction agent and excess oil stream. Which contains metal catalysts
