Abstract:
The present invention primarily relates to a process for producing certain phosphorus-containing cyanohydrin esters of formula (I) and the use thereof for producing glufosinate/glufosinate salts. The present invention further relates to a process for producing glufosinate/glufosinate salts.

Claim (Index 1):
Process for producing a compound of formula (I) wherein a compound of formula (II) is reacted with a compound of formula (III) wherein in each case: R 1  represents (C 1 -C 12 )-alkyl, (C 1 -C 12 )-haloalkyl, (C 6 -C 10 )-aryl, (C 6 -C 10 )-haloaryl, (C 7 -C 10 )-aralkyl, (C 7 -C 10 )-haloaralkyl, (C 4 -C 10 )-cycloalkyl or (C 4 -C 10 )-halocycloalkyl, R 2  represents (C 1 -C 12 )-alkyl, (C 1 -C 12 )-haloalkyl, (C 6 -C 10 )-aryl, (C 6 -C 10 )-haloaryl, (C 7 -C 10 )-aralkyl, (C 7 -C 10 )-haloaralkyl, (C 4 -C 10 )-cycloalkyl or (C 4 -C 10 )-halocycloalkyl, R 3  and R 4  each independently of one another represent hydrogen, (C 1 -C 4 )-alkyl, phenyl or benzyl, R 5  represents (C 1 -C 12 )-alkyl, (C 1 -C 12 )-haloalkyl, (C 6 -C 10 )-aryl, (C 6 -C 10 )-haloaryl, (C 7 -C 10 )-aralkyl, (C 7 -C 10 )-haloaralkyl, (C 4 -C 10 )-cycloalkyl or (C 4 -C 10 )-halocycloalkyl, X represents oxygen or sulfur and n is 0 or 1, in the presence of one or more free-radical-forming substances (IV), wherein two separate mixtures (G1) and (G2) are metered into the reactor and these mixtures (G1) and (G2) have the following composition: mixture (G1) comprises one or more compounds of formula (II) and one or more free-radical-forming substances (IV) and mixture (G2) comprises one or more compounds of formula (III), one or more compounds of formula (II) and optionally one or more free-radical-forming substances (IV).
