Abstract
DC60 (03/12/56) การประดิษฐ์นี้ให้กรรมวิธีสำหรับทำโพรพิลีน ออกไซด์ (propylene oxide) ให้บริสุทธิ์, ซึ่ง กรรมวิธีรวมถึง (1) สารละลายที่มีโพรพิลีน, โพรพิลีน ออกไซด์, ตัวทำละลายอินทรีย์ และน้ำ และ สารละลายแอเควียสของตัวทำละลายอินทรีย์ในรูปสารสกัดชนิดแรกถูกส่งไปยังคอลัมน์สกัด-กลั่น ทำบริสุทธิ์ชุดแรกเพื่อดำเนินการแยก, ซึ่งสภาวะกลั่นทำบริสุทธิ์ในคอลัมน์สกัด-กลั่นทำบริสุทธิ์ ชุดแรกถูกควบคุมเพื่อให้ผลิตภัณฑ์ยอดหอของคอลัมน์ที่เต็มไปด้วยโพรพิลีนถูกทำให้ได้จาก ยอดคอลัมน์ของคอลัมน์สกัด-กลั่นทำบริสุทธิ์ชุดแรก, และผลิตภัณฑ์ก้นหอของคอลัมน์ที่เต็มไป ด้วยโพรพิลีน ออกไซด์, ตัวทำละลายอินทรีย์และน้ำถูกทำให้ได้จากก้นคอลัมน์ของคอลัมน์สกัด- กลั่นทำบริสุทธิ์ชุดแรก; (2) ผลิตภัณฑ์ก้นหอของคอลัมน์ที่เต็มไปด้วยโพรพิลีน ออกไซด์, ตัวทำละลายอินทรีย์และน้ำที่ได้จากก้นคอลัมน์ของคอลัมน์สกัด-กลั่นทำบริสุทธิ์ชุดแรกถูกแยกเพื่อ ทำให้ได้ผลิตภัณฑ์โพรพิลีน ออกไซด์ และสารละลายที่มีตัวทำละลายอินทรีย์และน้ำ กรรมวิธีนี้มี การใช้พลังงานต่ำ, กรรมวิธีทางเทคนิคอย่างง่าย และผลได้โพรพิลีน ออกไซด์ที่สูง : DC60 (03/12/56) This invention provides a process for the purification of propylene oxide, which includes (1) a solution containing propylene, propylene oxide, an emitter. The organic solvent and water and aqueous solution of the organic solvent in the first extract form are sent to the extraction-distillation column. The first purification is performed to perform the separation, in which the distillation is purified in the extraction column. The first batch was controlled so that the tower top product of the polypropylene-filled column was made from The top of the column of the extraction-distillation column made the first purification, and the bottom-tower product of the column filled with propylene oxide, organic solvent and water was obtained from the bottom of the column of the extraction-distillation column to do the first purification; (2) The column bottom product of the column is filled with propylene oxide, organic solvent and water obtained from the column bottom of the extraction-distillation column. This results in propylene oxide products and solutions containing organic solvents and water. This process has Low energy consumption, simple technical process And the result was polypropylene High oxide:
