Abstract

Method of preparation of the crystal enantiomorfous isomers of (S)--α-cyano-3-phenoxybenzilic ether-3-(2-chlorine-3,3,3-fluorine prop-1-en-1-il)-2-2-dimethylcyclopropanic acid and (R)-α-cyano-3-phenoxybenzilic ether of 1(S), cis)-3-(2-2-chlorine-3,3,3-fluorineprop-1-en-1-il)-2-2-dimethylcyclopropanic acid.The method consists in the fact, that α-cyano-3-phenoxybenzilic ether-3-(2-chlorine-3,3,3-fluorineprop-1-en-1-il)-2-2-dimethylcyclopropanic acid is solved in the organic solvent, selected from C2-C5-alkanols or C1-C8-alkans at mass ratio 1:1-2, obtaining solvent is cold up to (-10)-(+5)°C, add seed crystels of enantiomarphous pais of isomers so that they are semained nonsoluble during 0,4-33 days, then precipitated crystals are separated or in case of necesity arc recrystallized.Preparing compound has more higher insecticide activity.
