摘要

The present invention particularly provides ammonia and 3- [n-parts to provide a mixture of n-butyl (3-amino-3-cyanopropyl) methylphosphinate and (3-amino-cyanopropyl) methylphosphinic acid ammonium salt. It relates to a method for producing glufosinate and glufosinate salts by reaction of oxy (methyl) phosphoryl] -1-cyanopropyl acetate. More generally, the present invention also provides a process for the preparation of phosphorus-containing α-aminonitriles of formulas (Ia) and (Ib) from the corresponding phosphorus-containing cyanohydrin esters (II), and their, glufosinate and glufosi It relates to the use as an intermediate for the production of nate salts.
