35597-44-5 - Uses and synthesis methods
introduction
Glufosinate (glufosinate-ammonium) is developed and produced by German Hirst Company (now Bayer Company). Its chemical name is 4_{Hydroxy (Methyl) Phosphonyl)-DL-homoalanine, and other names are glufosinate. It is a glutamine synthesis inhibitor and a non-selective contact herbicide. Studies have shown that its herbicidal activity is limited to L-isomers. Although the commodity is DL mixture, the D body does not have biological herbicidal activity, so the biological activity of L-glufosinate is twice that of DL racemates with the same concentration.
market outlook
The development and commercialization of L-glufosinate was first completed by Meiji Company of Japan, because its products are single effective isomers, which have the advantages of less environmental chemical substances and more environmental protection in the production process, and have good market prospects and environmental compatibility. The L-glufosinate isomer has been registered in China.
Refining method
A method for the separation and refining of L-glufosinate:
It is characterized in that the crude glufosinate is added to the acidic aqueous solution, heated to form a dissolution balance, and then cooled to precipitate a solid, filtered, and the filtrate is post-processed to obtain refined L-glufosinate; the content of L-glufosinate in the crude glufosinate is greater than 52%; The pH value of the acidic aqueous solution is 1.2 to 4.0.

35597-44-5 - Reference Information
| Introduction | Glufosinate (glufosinate-ammonium) is developed and produced by Hirst Company of Germany (now Bayer Company), and its chemical name is 4-{Hydroxy (Methyl) phosphonyl}-DL-high alanine, other names are glufosinate salts, etc. It is a glutamine synthesis inhibitor and a non-selective contact herbicide. Studies have shown that its herbicidal activity is limited to L-isomers. Although the commodity is DL mixture, the D body does not have biological herbicidal activity, so the biological activity of L-glufosinate is twice that of DL racemates with the same concentration. |
| use | glufosinate is an efficient, broad-spectrum and low-toxicity non-selective herbicide developed by Hoechst Company of Germany. L-glufosinate (also known as refined glufosinate) is the only natural allelopathy herbicide with C- P-C structure so far. The herbicidal activity is about 4 times that of glyphosate, 2 times that of paraquat, and 2 times that of racemate glufosinate (DL-type). |
| market prospect | the development and commercialization of L-glufosinate was first completed by Meiji company of Japan, because its product is a single effective isomer, has the advantages of less amount of environmental chemical substances, more environmental protection in the production process, etc., and has good market prospect and environmental compatibility. The L-glufosinate isomer has been registered in China. |
| Refining method | A method for separating and refining L-glufosinate: it is characterized in that crude glufosinate is added to an acidic aqueous solution, heated to form a dissolution equilibrium, and then cooled to precipitate solids, filtered, and the filtrate is post-processed to obtain refined L-glufosinate; the content of L-glufosinate in the crude glufosinate is greater than 52%; the pH value of the acidic aqueous solution is 1.2 to 4.0. |
