METHOD FOR PRODUCING OCTYL ETHER WITH NORMAL OR ISOMERIC STRUCTURE OF 2,4-DICHLOROPHENOXYACETIC ACID AND HERBICIDAL AGENT CONTAINING ETHER PRODUCED BY SAID METHOD Russian patent published in 2018 - IPC A01N39/04 

FIELD: agriculture.

SUBSTANCE: group of inventions relates to agriculture, namely to method for producing compounds to control weeds. Method for producing octyl ester with normal or isomeric structure of 2,4-dichlorophenoxyacetic acid involves chlorination of octyl ester with normal or isomeric structure of phenoxyacetic acid. Herbicidal agent contains 2,4-dichlorophenoxyacetic acid in the form of octyl ester with normal or isomeric structure as an active ingredient and auxiliary components, wherein the octyl ester with normal or isomeric structure of 2,4-dichlorophenoxyacetic acid is prepared in said manner, and the herbicidal agent additionally comprises the resulting octyl ester with normal or isomeric structure of trichlorophenoxyacetic acid.

EFFECT: proposed method for producing octyl ester with normal or isomeric structure of 2,4-dichlorophenoxyacetic acid and herbicidal agent based on it makes it possible to substantially simplify the technology and reduce the amount of production and sewage wastes while maintaining the herbicidal activity of the herbicidal agent.
