Abstract
กรรมวิธีสำหรับการเตรียมของฟอสโฟโนเมธิลไกลซีนในผลได้เกือบจะเชิงปริมาณซึ่ง กำจัดการใช้ประโยชน์ของตัวเร่ง ปฏิกิริยาร่วมชนิดโลหะมีสกุลและปัญหาที่เกี่ยวข้องกับโลหะนี้ ออกไปได้ ในกรรมวิธีแก๊สที่มีออกซิเจน อยู่ด้วยนี้ถูกแทนที่ด้วย ไนโดรเจนเปอร์ออกไซด์ที่ว่องไวทางเคมีมากขึ้น ซึ่งเมื่อรวมกัน กับแอคทิเวเทด คาร์บอน แล้วจะออกซิไดส์ PMIDA ให้เป็น PMG ได้ในผลได้สูงมาก ปริมาณของตัวออกซิไดส์ที่ปล่อยให้ทำ ปฏิกิริยากับ PMIDA นี้เป็นฟังก์ชันของความเข้มข้นของออกซิเจน ในผลิตภัณฑ์ของปฏิกิริยาที่เป็นแก๊สและถูกควบคุมโดยการติด ตามความเข้มข้นนั้น ในอีกวิธีหนึ่ง สาร ออกออกซิไดส์นี้เป็น แก๊สที่มีออกซิเจนอยู่ด้วย ในอีกกรณีหนึ่งติดตามความเข้มข้น ของออกซิเจน ในผลิต ภัณฑ์ของปฏิกิริยาที่เป็นแก๊สเพื่อตรวจ หาจุดสิ้นสุดของปฏิกิริยานี้ The process for the preparation of phosphonomethylglycine was almost quantifiable. Eliminate the utilization of the accelerator. The noble metal cofactors and problems associated with this metal are evident in the oxygenation gas process. This address has been replaced with More chemically active nitrogen peroxide Which, when combined With activated carbon, PMIDA is highly oxidized to form PMG. The amount of oxidizing agent that is released to react with PMIDA is a function of the oxygen concentration. In the products of the gas reaction and is controlled by the According to that concentration On the other hand, this oxidizer is Gas with oxygen In other cases, monitoring the oxygen concentration in the gas reaction product to determine Find the end of this reaction.
