AI Technical Summary

Problems solved by technology

The problem that above-mentioned technical scheme exists is: 1. organic solvent consumption is big
The problems of the above-mentioned technical scheme are: ① the amount of auxiliary agents is large, and the total amount of auxiliary agents such as emulsifiers, penetrants, stabilizers and co-solvents can be as high as 36%; ② emulsifiers are not environmentally friendly, and nonylphenol polyoxyethylene is also used ether
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

[0054] Example 1 A 10% environment-friendly dinotefuran microemulsion

[0055] Raw material ratio:

[0056]

[0057] Prepared by:

[0058] 1. prepare various raw materials for preparing 1000kg microemulsion according to formula weight ratio;

[0059] II. Add sodium lauryl sulfate, Tween-30, and sodium linoleate into the stirred tank respectively, add deionized water, stir, and dissolve to obtain solution A;

[0060] III. Add dinotefuran into the solvent cyclohexanone, stir and dissolve to obtain solution B;

[0061] IV. Add solution B to solution A, stir, 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 .

[0062] The testing items, methods and quality standards of the 10% dinotefuran microemulsion prepared in this example are listed in Table 1.

Abstract

The invention provides an environment-friendly dinotefuran microemulsion which is prepared from the following components in percentage by weight: 1 to 20 percent of dinotefuran , 4 to 10 percent of anionic surface active agent, 2 to 12 percent of non-ionic surface active agent, 5 to 12 percent of ketone solvents with a boiling point above 150 DEG C, 0.01 to 0.04 percent of defoaming agent, and the balance of water, wherein the anionic surface active agent is selected from one or more of anionic surface active agents, wherein the hydrophobic group of the anionic surface active agents is vegetable oil hydrolyzed or pyrolysed linear chain alkyl or alkenyl, and the hydrophilic group of the anionic surface active agents is selected from carboxyl, acidophobe or sulfonic acid group; the non-ionic surface active agent is selected from one or more of polyethoxylated non-ionic surface active agents, wherein the hydrophobic group of the non-ionic surface active agent is vegetable oil or vegetable oil hydrolyzed or pyrolysed linear chain alkyl or alkenyl. The invention also provides a preparation method of the environment-friendly dinotefuran microemulsion.

Description

technical field [0001] The invention belongs to the field of new formulations of pesticides, in particular to a new environmentally friendly dinotefuran microemulsion using a plant-derived emulsifier and a preparation method thereof. Background technique [0002] Pesticides (referring to pesticide preparations in this specification) 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 ge...
