Beschreibung
Zusammenfassung:	The present invention relates primarily to a process for preparing certain phosphorus- containing cyanohydrins of the formula (I), and also to certain phosphorus-containing cyanohydrins per se and to their use for the preparation of glufosinate and/or glufosinate salts. The present invention further relates to certain mixtures particularly suitable for preparing the phosphorus-containing cyanohydrins of the formula (I). La présente invention concerne tout d'abord un procédé de préparation de certaines cyanhydrines contenant du phosphore de formule (I), ainsi que les cyanhydrines contenant du phosphore ainsi obtenues et leur utilisation pour préparer du glufosinate ou des sels de glufosinate. L'invention concerne par ailleurs des mélanges donnés convenant particulièrement à la préparation des cyanhydrines contenant du phosphore de formule (I).
