Abstract
คำขอใหม่ปรับปรุง วิธีการสำหรับการทำให้บริสุทธิ์ของอะซีโตไนไตรล์ (acetonitrile) ของการประดิษฐ์ปัจจุบัน ประกอบด้วย การทำให้ได้สารละลายปฏิกิริยาโดยการป้อนอะซีโตไนไตรล์ดิบที่ได้มาโดยปฏิกิริยา การแอมมอกซิเดชันและด่างสู่ภาชนะปฏิกิริยา; การทำให้ได้สิ่งกลั่นโดยการกลั่นสารละลาย ปฏิกิริยา; และการป้อนอะซีทาไมด์และ/หรือกรดอะซีติกสู่ภาชนะปฏิกิริยา: New requests, improvements Methods for purification of acetonitrile The acetonitrile of the present invention consists of obtaining a reaction solution by feeding the raw acetonitrile obtained by the reaction. Amoxication and alkalinity to reaction vessels; Obtaining distillation by distillation of reaction solutions; And the feeding of acetamide and / or acetic acid into the reaction vessel:
