Abstract

The invention discloses preparation and application research of oil-soluble and water-soluble aryloxy phenoxy carboxylic acids and carboxylate compounds. As shown in general formulae (I, II), n is equal to 0, 1, 2, 3, 4, 5, or the like, or (CH2)n and represents a branched alkyl; Y represents Cl-, Br-, F-, I-, AcO-, acetyl salicylate radical, a citrate radical, salicylate radical, p-toluenesulfonate radical, hydrogen sulfate radical, or other negative ions; R1 represents alkyl with 1-6 carbon atoms, alkoxy with 1-6 carbon atoms, alkenyl with 1-6 carbon atoms, or aryl; R2 represent alkyl with 1-6 carbon atoms, alkoxy with 1-6 carbon atoms, alkenyl with 1-6 carbon atoms, or aryl; or R1 and R2 adopt the following structure; and Ar is one of the following groups.

Description

Technical field: [0001] The invention relates to the preparation and herbicidal activity of a novel aryloxyphenoxycarboxylate derivative which is compatible with water and oil. . Background technique: [0002] The traditional pesticide dosage forms are mainly emulsifiable concentrate, wettable powder, powder and granule. With the research and development of new pesticide dosage forms, it will develop in the direction of water, water emulsion and microemulsion in the future. From this development trend, This puts forward higher requirements for the new pesticide molecules that are about to be successfully developed. Not only must they be highly efficient, low-toxic, safe and environmentally friendly, but also hope that the drug molecules have a certain water solubility. It can be used directly as an aqueous preparation, which can not only reduce the production cost but also reduce the environmental pollution caused by the addition of a large amount of solvents, surfactants, ...
