Paragraph 0033-0044; 0056-0057, (2022/01/08)
The invention relates to the technical field of pesticides, and particularly discloses an L-glufosinate ammonium salt crystal form, a preparation method and application thereof. The crystal form of the L-glufosinate ammonium salt has characteristic diffraction peaks at the positions of 2theta+/-0.2 degrees which are equal to 9.10 degrees, 10.05 degrees, 16.77 degrees, 17.67 degrees, 18.30 degrees, 18.83 degrees, 23.47 degrees, 24.10 degrees, 25.61 degrees, 28.55 degrees, 29.01 degrees and 33.40 degrees. In the novel crystal form of L-glufosinate ammonium, the molar ratio of glufosinate ammonium to ammonium ions is close to 1: 1, the ammonium ion content is high, the crystal form stability is good, the ammonia content is not obviously reduced after long-time storage, the crystal form structure is not changed, the hygroscopicity is low, development, preparation and storage of weeding drug products are facilitated, and the novel crystal form has high application and popularization value.
Method for preparing phosphorus-containing a-aminonitriles
-
Paragraph 0148; 0158, (2021/06/22)
The present invention relates primarily to processes conducted in a continuously operated reactor for preparing particular phosphorus-containing α-aminonitriles of the formulae (Ia) and (Ib) defined hereinafter from corresponding phosphorus-containing cyanohydrin esters and to the use thereof for preparation of glufosinate or of glufosinate salts. The present invention further relates to a process for producing glufosinate/glufosinate salts.
