Problems solved by technology

The benzene series solvents used in the emulsifiable concentrate are flammable, explosive and toxic. These organic solvents are easy to pollute the environment and have potential hidden dangers to the health of producers and users
Therefore, the use of benzene series solvents is increasingly restricted

Embodiment 1

[0017] Embodiment 1 Application of sulfonated kerosene in 2.5% beta-cypermethrin EC

[0018] First, take by weight percentage: beta-cypermethrin technical 2.5%, emulsifier 8%, and the balance is sulfonated kerosene.

[0019] The preparation method of the emulsifiable concentrate: first weigh each raw material according to the above weight percentage, then dissolve the original drug of beta-cypermethrin with a small amount of sulfonated kerosene, add an emulsifier to mix, and finally fill up to 100% with sulfonated kerosene, that is The emulsifiable concentrate of the present invention is obtained.

Embodiment 2

[0020] Embodiment 2 The application of reference solvent xylene in 2.5% beta-cypermethrin emulsifiable concentrate

[0021] Firstly, take by weight percentage: 2.5% of the original drug of beta-cypermethrin, 8% of emulsifier, and the balance of xylene.

[0022] The preparation method of the emulsifiable concentrate: firstly weigh each raw material according to the above weight percentage, then dissolve the active drug of beta-cypermethrin with a small amount of xylene, add an emulsifier to mix, and finally fill up to 100% with xylene to obtain The emulsifiable concentrate of the present invention.

Embodiment 3

[0023] Example 3 Application of sulfonated kerosene in 4.5% beta-cypermethrin EC

[0024] First weighed by weight percentage: beta-cypermethrin technical 4.5%, emulsifier 12%, and the balance is sulfonated kerosene.

[0025] The preparation method of the emulsifiable concentrate: first weigh each raw material according to the above weight percentage, then dissolve the original drug of beta-cypermethrin with a small amount of sulfonated kerosene, add an emulsifier to mix, and finally fill up to 100% with sulfonated kerosene, that is The emulsifiable concentrate of the present invention is obtained.

Abstract

The invention relates to the field of pesticide preparations, and discloses a benzene-series solvent substitute sulfonated kerosene and application of sulfonated kerosene in beta-cypermethrin emulsifiable concentrate. According to the invention, sulfonated kerosene in the formula can well substitute benzene-series solvents common in beta-cypermethrin emulsifiable concentrate, and the obtained emulsifiable concentrate has better stability and dispersity; use amount of benzene, methylbenzene and xylene in pesticide emulsifiable concentrate can be reduced, poison to the human body and pollution to the environment caused by benzene-series solvents can be reduced, and besides, the production cost of the emulsifiable concentrate is reduced.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to a sulfonated kerosene as a benzene series solvent substitute and its application in beta-cypermethrin emulsifiable concentrate. Background technique [0002] EC refers to a homogeneous transparent oily liquid prepared by dissolving the original drug (crude oil or raw powder) in an organic solvent in a certain proportion, and then adding a certain amount of special emulsifier for pesticides and other additives. Generally, after diluting with a large amount of water, it can become a stable emulsion. The emulsifier in the emulsifiable concentrate mostly uses a mixture of non-ionic and anionic surfactants, and the solvent mostly uses benzene, toluene, xylene or mixed benzene, etc. In addition, alcohol solvents such as methyl isobutyl ketone and isopropanol are also used. [0003] EC is currently the main pesticide formulation in my country, and solvents are an indispensable and...
