Abstract
ในกระบวนการสำหรับการแยกแอมโมเนียและน้ำออกโดยการกลั่นจากของผสมได้มา ในการเตรียมโพลีเอไมด์โดยประกอบรวมด้วยแลคทัมและ/หรือไดแอมีน, และในบางกรณีอะมิโน ไนไทรล์และ/หรือไดไนไทรล์, และรวมถึงสิ่งเจือปนไซโคลเพนทาโนนในสองขั้นตอน 1) ของผสมถูกกลั่นจาก 11 ถึง 35 บาร์ให้, เป็นผลิตผลที่ส่วนบน T1, น้ำ, แอมโมเนียและ ไซโคลเพนทาโนน, และ, เป็นสารส่วนล่าง B1, น้ำ, แลคทัมและ/หรือ ไดแอมีน, และ, เมื่อมีอยู่, อะมิโนไนไทรล์และ/หรือไดไนไทรล์, และ 2) T1 ถูกกลั่นจาก 11 ถึง 35 บาร์ให้, เป็นผลิตผลที่ส่วนบน T2, แอมโมเนียและไซโคล เพนทาโนน, และ, เป็นผลิตผลส่วนล่าง B2, น้ำ: In the process for the separation of ammonia and water by distillation from mixtures is obtained. In polyamide preparations containing lactum and / or diamine, and in some cases amino Nitrile and / or dinitrile, and including cyclopentanone impurities in two steps 1) The mixture was distilled from 11 to 35 bar, producing T1 upper, water, ammonia and Cyclopentanone, and, as a substrate B1, water, lactum and / or diamine, and, when present, aminonitrile and / or dinitrile, and 2) T1 is distilled from 11 to 35 bar, is the upper product T2, ammonia and cyclopentanone, and, as a bottom B2, water:
