Abstract
การเกิดออกซิเดชันของ p-ไซลีนเพื่อผลิต เทเรฟแธลิค แอซิด ดำเนินไปได้ โดยใช้ออกซิเจนบริสุทธิ์หรือออกซิเจนที่เกือบ บริสุทธิ์และระบายความร้อนโดยการระเหย ผล พลอยได้และของเสีย จะลดลงการใช้ประโยชน์จากออกซิเจนจะได้รับการเสริมขึ้น มี การใช้ภาวะ ของการดำเนินงานตามที่ต้องการ และสามารถป้องกัน ความจำเป็นของพื้นผิวที่มีการแลกเปลี่ยน ความร้อนโดยการ สัมผัสโดยตรงในภาชนะที่มีเครื่องปฏิกรณ์ได้ The oxidation of p-xylene to produce terephthalic acid is carried out using pure oxygen or almost oxygen. Purified and cooled by evaporation of by-products and waste Will be reduced, the utilization of oxygen will be enhanced, the desired operating conditions are used. And can prevent The necessity of exchanged surfaces Heat by Directly in contact with the reactor container.
