METHOD OF DETERMINATION OF 3-(2,2-DICHLOROETHYNYL)-2,2-DIMETHYL- -CYCLOPROPANE-1-CARBOXYLIC ACID 3-PHENOXY-α-CYANOBENZYL ESTER ISOMERS Russian patent published in 1999 - IPC

Abstract RU 2132056 C1

FIELD: analytical chemistry. SUBSTANCE: invention relates to a method of determination of isomers of 3-(2,2-dichloroethynyl)-2,2-dimethylcyclopropane-1-carboxylic acid 3-phenoxy-α-cyanobenzyl ester by high-pressure liquid chromatography method. Silica gel-base sorbent is used as a stationary phase and a mixture of hexane with tetrahydrofuran or ethyl acetate at volume ratio 100:(0.1-0.6) is used as an eluent. Invention provides the development of the more effective method of determination of isomers of 3-(2,2-dichloro- -ethynyl)-2,2-dimethylcyclopropane-1-carboxylic acid 3-phenoxy-α-cyanobenzyl ester. EFFECT: enhanced effectiveness of the method. 4 ex
