Abstract
การปรับปรุงให้ดียิ่งขึ้นของกรรมวิธีคาร์บอนิเลชันของเมธานอลสำหรับการผลิตกรดอะซีทิก ได้รับการเปิดเผย การเปิดเผยอย่างจำเพาะเป็ นวิธีการสำหรับการลดการก่อรูปของแอลคิลไอโอไดด์ และกรดคาร์บอกซิลิก ที่มี C3-8 โดยการกำจัดสารประกอบเพื่อการรีดิวส์เพอร์แมงกาเนท ("PR C'S') จากวัฎภาคเบาของกระแสส่วนด้านบนของส่วนกลั่นเบาที่ได้รับกา รควบแน่น ซึ่งมี (a) การกลั่น วัฎภาคเบาเพื่อให้ผลผลิตที่ได้ของก ระแสส่วนด้านบนที่อุดมไปด้วย PRC และ (b) การสกัดกระแส ส่วนด้านบนก ระแสที่สามด้วยน้ำในระยะที่ตามกันอย่างน้อยที่สุดสองระยะ และก ารแยกกระแส ชนิดแอคเควียสที่มี PRC's หนึ่งกระแสหรือมากกว่านั้นออ กจากที่นั้น Optimization of methanol carbonization for acetic acid production Has been revealed Specific disclosure is Methods for reducing the formation of alkyl iodide And carboxylic acid containing C3-8 by removal of the redox permanganate compound ("PR C'S ') from the light cycle of the upper current portion of the light distillate at It was condensed which contains (a) light cycle distillation to provide the The PRC-rich upper part and (b) the extraction of the third upper part with water at at least two consecutive phases and the extraction of the active type. With one or more PRC's from there
