Embodiment 1

[0020] Embodiment one: 15% cyhalofop-ethyl emulsifiable concentrate

[0021] According to the technical scheme of the present invention, take by weighing 13 grams of itaconic acid, take by weighing 10 grams of triethylamine with a molar ratio of 1:1, and mix the two evenly. Then slowly add 15.5 grams of 97% cyhalofop-ethyl powder, 51.5 grams of solvent turpentine-based vegetable oil to fully dissolve the cyhalofop-ester, then add 5.4 grams of calcium dodecylbenzenesulfonate, styrene-based phenolic poly Oxyethylene ether 4.6 grams, continue to stir until mixing evenly, obtain 15% cyhalofop-ethyl emulsifiable concentrate.

Embodiment 2

[0022] Embodiment two: 240g / L clethodim emulsifiable concentrate

[0023] According to the technical scheme of the present invention, take by weighing 6.5 grams of itaconic acid, take by weighing 5 grams of triethylamine with a molar ratio of 1:1, and mix the two evenly. Then slowly add 29.5 grams of 85% clethodim crude oil, 20 grams of solvent sec-butyl acetate, 22.5 grams of turpentine-based vegetable oil, make it fully mixed, and then add 3.6 grams of calcium dodecylbenzenesulfonate, styrylphenol 6.8 grams of polyoxyethylene ether, 4.6 grams of castor oil polyoxyethylene ether, 1.5 grams of 2,6-di-tert-butyl-4-methylphenol, and continue to stir until uniformly mixed to obtain 240g / L (25%) clethodim EC (density ρ: 1.0417).

Embodiment 3

[0024] Embodiment three: 20% quizalofop-p-ethyl emulsifiable concentrate

[0025] According to the technical scheme of the present invention, take by weighing 19.5 grams of itaconic acid, take by weighing 15 grams of triethylamine with a molar ratio of 1:1, and both mix uniformly. Slowly add 21.06 grams of 95% quizalofop-ethyl essence former powder, solvent is solvent naphtha 150#20 grams, 9.44 grams of rosin-based vegetable oils, make it fully dissolve and mix evenly, then add 7.5 grams of calcium dodecylbenzenesulfonate, 2.0 grams of styrylphenol polyoxyethylene ether and 5.5 grams of castor oil polyoxyethylene ether were stirred until uniformly mixed to obtain 20% quizalofop-p-ethyl emulsifiable concentrate.

Abstract

The invention discloses an application technology of itaconic acid derivatives in herbicide emulsifiable concentrate. The herbicide emulsifiable concentrate comprises itaconic acid derivatives, herbicide effective ingredients, an emulsifier, a stabilizer, a pH regulator and a solvent. The itaconic acid derivatives are prepared by the reaction of itaconic acid with triethylamine, and the molar ratio of the itaconic acid to the triethylamine is 1:1. A herbicide emulsifiable concentrate system formulated with the itaconic acid derivatives replaces non-environmentally friendly solvents, consumption of high-toxicity organic solvents such as benzene is reduced, environmental pollution is alleviated, and herbicidal effect is improved.

Description

technical field [0001] The invention relates to the field of pesticide preparation processing, in particular to an applied technology for processing pesticide herbicide emulsifiable concentrate. Background technique [0002] Toluene, xylene, dimethylformamide, cyclohexanone and other non-environmentally friendly solvents were widely used in the processing of pesticide preparations in the past, but these solvents have low flash point, volatile, flammable and explosive, high toxicity, Long half-life and other disadvantages, large-scale use has great hidden dangers to production safety, human health and ecological environment. [0003] In recent years, relevant state departments have issued a series of relevant policies to restrict or even prohibit the use of such solvents in the processing of pesticide preparations, making it almost impossible for EC and other manufacturers to process pesticide preparations with light aromatic solvents such as toluene and xylene. In this cont...
