Embodiment 1

[0015] Take 0.60g of ionic liquid 1-butyl-3-methylimidazole chloride, 0.78g of ethylene glycol monobutyl ether, and 1g of water and mix them evenly in a 20ml test tube, and ultrasonically oscillate for 10min; , weighed 0.12g of acetamiprid (4% mass fraction), and ultrasonically oscillated for 30 minutes; after it was basically in a uniform milky state, added 0.28g of emulsifier HSH433 (10.1% mass fraction), and ultrasonically oscillated for about 1 hour; until the solution was uniform and transparent , Stand for 2h, observe whether there is crystallization or stratification. The cold storage stability and hot storage stability were investigated at -5°C and 54±2°C respectively, and it was still stable after cold or hot storage for 14 days.

Embodiment 2

[0017] Take 0.60g of ionic liquid 1-butyl-3-methylimidazole chloride, 0.78g of ethylene glycol monobutyl ether, and 1g of water and mix them evenly in a 20ml test tube, and ultrasonically oscillate for 10min; , weigh acetamiprid 0.30g (10% mass fraction), and ultrasonically oscillate for 30 minutes; after the basic uniform milky state, add 0.28g emulsifier HSH433 (9.5% mass fraction), ultrasonically oscillate for about 1 hour; until the solution is uniform and transparent , Stand for 2h, observe whether there is crystallization or stratification. The cold storage stability and hot storage stability were investigated at -5°C and 54±2°C respectively, and it was still stable after cold or hot storage for 14 days.

Embodiment 3

[0019] Take 0.60g of ionic liquid 1-butyl-3-methylimidazole chloride, 0.78g of ethylene glycol monobutyl ether, and 1g of water and mix them evenly in a 20ml test tube, and ultrasonically oscillate for 10min; , weigh 0.23g (8% mass fraction) of acetamiprid, and ultrasonically oscillate for 30 minutes; after it is basically in a uniform milky state, add 0.28g emulsifier OP10 (9.7% mass fraction), and ultrasonically oscillate for about 1 hour; until the solution is uniform and transparent , Stand for 2h, observe whether there is crystallization or stratification. The cold storage stability and hot storage stability were investigated at -5°C and 54±2°C respectively, and it was still stable after cold or hot storage for 14 days.

Abstract

The invention discloses an insecticidal agricultural pesticide preparation using an ionic liquid as a cosolvent and a method for preparing the insecticidal agricultural pesticide preparation, belonging to the technical field of agricultural pesticide preparations. The agricultural pesticide preparation comprises 1-10wt% of pesticide, 10-25wt% of ionic liquid, 10-40wt% of water, 10-30wt% of latentsolvent and 5-8wt% of emulsifying agent. The insecticidal agricultural pesticide preparation can effectively avoid serious environment, health and safety problems caused by using a conventional organic solvent; simultaneously, the ionic liquid in the insecticidal agricultural pesticide preparation has an amphipathic property and can regulate the dissolving capacity of the agricultural pesticide; and the prepared agricultural pesticide preparation has simple components, transportation safety and low toxicity.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, and in particular relates to an insecticidal pesticide preparation using ionic liquid as a co-solvent and a preparation method thereof. Background technique [0002] In the development of the pesticide processing industry, traditional organic solvents are flammable and explosive and cause serious environmental pollution, resulting in flammable and explosive preparations and environmental pollution problems, which are extremely unsafe in the process of production, storage, transportation and use. It has been a long-standing dream to develop environmentally friendly pesticide formulations. Ionic liquids have both liquid and solid characteristics, are non-flammable and explosive, and have strong selective solubility for inorganic and organic substances; by changing anions, cations and side chains, an ideal ionic liquid solvent can be designed to provide a new development for the futur...
