Abstract
การประดิษฐ์นี้เกี่ยวกับวิธีการสำหรับการแสดงเชิงปริมาณของปริมาณของสารเจือปน ในแลคไทด์ วิธีการดังกล่าวมีลักษณะเฉพาะในที่ว่าการแสดงเชิงปริมาณของสารเจือปนนั้น เป็นโดยใช้เป็นพื้นฐานด้วยการตรวจวัดที่ดำเนินการบนการดูดกลืน ในบริเวณอินฟราเรดใกล้ ของสเปกตรัมแม่เหล็กไฟฟ้า ด้วยวิธีการนี้, สามารถหาปริมาณเล็กน้อยของสารเจือปน เช่นน้ำ, กรดอิสระกลุ่มสาร หรือทั้งสองแบบเชื่อมต่อกับคอมพิวเตอร์ในของผสมปฏิกิริยาของแลคไทด์ ในลักษณะที่ค่อนข้างง่าย สิ่งนี้ยอมให้สำหรับการเฝ้าสังเกตแบบเชื่อมต่อกับคอมพิวเตอร์ที่ง่าย ของกรรมวิธีการผลิตของแลคไทด์ This invention relates to a method for the quantitative expression of the dopant in lactide. The method is unique in that the quantitative representation of the dopant. It is based on the measurements performed on the absorption. In the near infrared region Of the electromagnetic spectrum In this way, small amounts of impurities such as water, free acids and other substances can be determined. Or both are connected to the computer in the Lactide reaction mixture. In a relatively simple manner This allows for easy computer-tethered monitoring. Of the production process of lactide
