Abstract

DC60 (09/09/57) วิธีการผลิตกรดเทเรฟทัลลิคได้ถูกนำมาอธิบายไว้ วิธีการนี้เกี่ยวข้องกับการใช้ กระแส 4-CBA ที่บริสุทธิ์อย่างมาก กระแส 4-CBA ที่บริสุทธิ์อย่างมาก ตัวทำละลายที่ ประกอบด้วยของเหลวไอออนิคและกรดคาร์บอกซิลิกซึ่งเป็นทางเลือก แหล่งโบรมีน ตัวเร่งปฏิกิริยา และสารออกซิไดซ์ถูกนำมาสัมผัสเพื่อผลิตผลิตภัณฑ์ซึ่งประกอบด้วยกรด เทเรฟทัลลิคDC60 (09/09/57) A method for producing terephthalic acid is described. The method involves the use of a highly pure 4-CBA stream, a highly pure 4-CBA stream, a solvent consisting of an ionic liquid and an alternative carboxylic acid, a bromine source, a catalyst, and an oxidizing agent are brought into contact to produce a product consisting of terephthalic acid.
