Abstract
การประดิษฐ์นี้เกี่ยวกับกรรมวิธีสำหรับการผลิตเมธิล เมแธคริเลท, ซึ่งประกอบรวมด้วย ขั้นตอนต่อไปนี้ A) การผลิตเมแธโครเลน และ B) ปฏิกิริยาของเมแธโครเลนที่ได้ในขั้นตอน A) ในปฏิกิริยาออกซิเดทีฟ เอสเทอริฟิเคชันเพื่อให้เมธิล เมแธคริเลท, ที่บ่งบอกลักษณะจากการที่ว่า สองขั้นตอน A) และ B) เกิดขึ้นในวัฏภาคของเหลวที่ความดันจาก 2 ถึง 100 บาร์, และทำขั้นตอน B) ในที่ที่มีตัวเร่งปฏิกิริยาที่มีโลหะมีสกุลที่ไม่เป็นเนื้อเดียวกันซึ่งประกอบ รวมด้วยโลหะ และ/หรือ ซึ่งประกอบรวมด้วยโลหะออกไซด์: This invention is about a process for producing methyl methacrylate, which includes The following steps A) production of methacrolol and B) methacrolide reaction obtained in step A) in oxidative reactions. Esterification for methyl methacrylate, characterized by the fact that two stages A) and B) occur in the liquid phase at pressures from 2 to 100 bar, and Take step B) in the presence of a catalyst with non-homogeneous noble metals incorporating metals and / or containing metal oxides:
