Problems solved by technology

The problems in the above-mentioned technical scheme are: 1. not only use organic solvent, but also use a large amount of organic solvent
The problems in the above-mentioned technical scheme are: 1. the environmental performance of the emulsifier is not good enough
This also reflects from another aspect that it is very difficult to prepare a dinotefuran microemulsion that meets the requirements of pesticide registration and can be sold on the market.

Embodiment 1

[0053] Example 1 A 10% organic solvent-free environmentally friendly dinotefuran microemulsion

[0054] Raw material ratio:

[0055]

[0056] Prepared by:

[0057] 1. prepare various raw materials for preparing 1000kg microemulsion according to formula weight ratio;

[0058] II. Add sodium linoleate, sodium lauryl sulfate, and Tween-80 to the stirring tank respectively, add deionized water, stir, and dissolve;

[0059] III. Add dinotefuran, stir, and make it dissolve to obtain a transparent solution;

[0060] IV. Then add tributyl phosphate defoamer, stir slightly, stand still, and filter to get the target product with a transparent appearance. For the sample photo, see figure 1 .

[0061] The samples were tested and found to meet the specified quality standards. The test items, methods and results are shown in Table 1.

[0062] Table 110% dinotefuran microemulsion testing items, testing methods and quality standards

[0063]

Embodiment 2

[0064] Example 2 A 5% Organic Solvent-Free Environmentally Friendly Dinotefuran Microemulsion

[0065] Raw material ratio:

[0066]

[0067] Adopt the preparation method and steps similar to Example 1, obtain 1000kg target product, see sample figure 1 .

Embodiment 3

[0068] Example 3 1%~9% Environmentally Friendly Dinotefuran Microemulsion Without Organic Solvent

[0069] Take 100kg of the 10% organic-solvent-free environment-friendly dinotefuran microemulsion obtained in Example 1, add different amounts of water as shown in Table 2, and stir to obtain 1% to 9% organic-solvent-free environment-friendly dinotefuran Amine microemulsion.

[0070] Table 2 dilution water consumption and obtain corresponding microemulsion concentration

[0071]

[0072] According to the above method, when different amounts of water are added to the 10% dinotefuran microemulsion, the system becomes a uniform and transparent solution without turbidity, precipitation and the like after a little stirring. It shows that dinotefuran with high concentration (10%) is uniformly and stably dispersed in the microemulsion of the present invention.

Abstract

The invention provides environment-friendly dinotefuran microemulsion free of an organic solvent and a preparation method thereof. The environment-friendly dinotefuran microemulsion is prepared from, by weight, 1-10% of dinotefuran, 4-10% of an anionic surfactant, 4-12% of a nonionic surfactant, 0.01-0.04% of a defoaming agent and the balance water. The anionic surfactant is selected from one or more of anionic surfactants with hydrophobic groups coming from vegetable oil hydrolytic or schizolytic linear chain alkyl groups or alkenyl groups and hydrophilic groups coming from carboxyl groups, sulfate groups or sulfonic groups. The nonionic surfactant is selected from one or more of polyoxyethylene ether nonionic surfactants with hydrophobic groups coming from vegetable oil or vegetable oil hydrolytic or schizolytic linear chain alkyl groups or alkenyl groups.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, and in particular relates to a new organic solvent-free, environmentally friendly dinotefuran microemulsion using a plant-derived emulsifier and a preparation method thereof. Background technique [0002] Pesticide preparations are special commodities for controlling agricultural and forestry crop diseases, insects, and weeds, and are indispensable means of production for modern agriculture. But it is also a "double-edged sword". On the one hand, through the application of pesticides, the country can recover about 30 billion kilograms of grain loss every year. On the other hand, the resulting food safety and environmental pollution problems are becoming increasingly prominent. The pollution caused by pesticides is caused by the active ingredients themselves, as well as by the solvents and auxiliaries in the formulation. Since the amount of solvents and additives is generally large, the sec...
