PREPARATION OF GLUFOSINATE BY CONVERTING 3-N-BUTOXY(METHYL)PHOSPHORYL-1-CYANOPROPYLACETATE TO A MIXTURE OF N-BUTYL(3-AMINO-3-CYANOPROPYL)-METHYLPHOSPHINATE AND (3-AMINO-3-CYANOPROPYL)-METHYLPHOSPHINIC ACID AMMONIUM SALT

摘要

The present invention relates primarily to processes 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 preparing glufosinate or glufosinate salts.
