PROCESS FOR THE PREPARATION OF CYPERMETHRINE ISOMERS

PROCESS FOR THE PREPARATION OF CYPERMETHRINE ISOMERS

The invention relates to the stable arthropodlical composition, containing as active component cypermetryn of formula:where carbon atoms 1,3 and α- are chiral carbon atom and the wavy line indicate the cys - or trans - spatial configuration, bearing on cyclopronanoic ring, containing, at least, 95 m...

Beschreibung
Zusammenfassung:The invention relates to the stable arthropodlical composition, containing as active component cypermetryn of formula:where carbon atoms 1,3 and α- are chiral carbon atom and the wavy line indicate the cys - or trans - spatial configuration, bearing on cyclopronanoic ring, containing, at least, 95 mass% of isomer blend, consisting of a pair of enantiomer IR cys S and IS cys R (Ia) and IR trans S and IS trans R (Ib) in weight ratio Ia:Ib = 55:45-25:75 or a pair of isomer Ia or Ib, which contains both stabilisator 0,001-0,1 mass% acid or acid mixture, that relates to the active component, preferably non-volatile carbonic acids with pK1 = 1-5 such as, ftalic acid, succinic acid, tartric acid, maleic acid, fumaric acid, malonic acid or one or several time substituted in chain, such derivative as alkylated derivatives of the given acids and/or oxalyc acid.
