Embodiment 1

[0034] A kind of synthesis technique of the technical compound of flufenoxate comprises the following steps:

[0035] S1, take out 20-43 parts of acifluorfen, 10-15 parts of emulsifier, 15-19 parts of methyl oleate, 3-8 parts of caustic soda, 7-10 parts of paraquat, 8- 15 parts of phenylphenol polyoxyethyl ether and 5-13 parts of ethyl acetate are put into a container for pulverization;

[0036] S2, heating a certain amount of deionized water to 25-30°C;

[0037] S3. Pour the heated deionized water into the container, stir with the medicine inside the container, and continue stirring and heating. When the reaction temperature is controlled at 70-80°C, react for 3-4 hours and then carry out precipitation, cleaning, and pressing. Filter and air-dry to obtain the original drug of acifluorfen.

Embodiment 2

[0039] A kind of synthesis technique of the technical compound of flufenoxate comprises the following steps:

[0040] S1, take out 21 parts of acifluorfen, 11 parts of emulsifier, 16 parts of methyl oleate, 4 parts of caustic soda, 7 parts of paraquat, 8 parts of phenylphenol polyoxyethyl ether and 5 parts of ethyl acetate are put into the container and pulverized;

[0041] S2, heating a certain amount of deionized water to 25°C;

[0042] S3. Pour the heated deionized water into the container, stir with the medicine inside the container, and continue to stir and heat. When the reaction temperature is controlled at 70°C, react for 3 hours and then carry out precipitation, cleaning, pressure filtration and air drying to obtain Ethoxyfluorfen technical drug.

Embodiment 3

[0044] A kind of synthesis technique of the technical compound of flufenoxate comprises the following steps:

[0045] S1, take out 22 parts of acifluorfen, 12 parts of emulsifier, 16 parts of methyl oleate, 4 parts of caustic soda, 8 parts of paraquat, 9 parts of phenylphenol polyoxyethyl ether and 6 parts of ethyl acetate are put into the container and pulverized;

[0046] S2, heating a certain amount of deionized water to 25°C;

[0047] S3. Pour the heated deionized water into the container, stir with the medicine inside the container, and continue to stir and heat. When the reaction temperature is controlled at 71°C, react for 3.1 hours and then carry out precipitation, cleaning, pressure filtration and air drying to obtain Ethoxyfluorfen technical drug.

Abstract

The invention discloses a synthesis process of a fluoroglycofen active compound. The fluoroglycofen active compound comprises 5-13 parts of ethyl acetate, 20-43 parts of acifluorfen, 10-15 parts of emulsifier, 15-19 parts of methyl oleate, 3-8 parts of caustic soda flake, 7-10 parts of paraquat, 8-15 parts of phenyl phenol polyoxyethylene ether and 30-50 parts of deionized water. By mixing ethyl acetate, acifluorfen, emulsifier, methyl oleate, caustic soda flake, paraquat, phenyl phenol polyoxyethylene ether and deionized water together according to a certain proportion, chemical reaction occurs, so that saving of time, quick action and high efficiency during dissolving are realized; a herbicide after being absorbed by weed can directly give play to effect to thoroughly kill the weed, so that convenience is brought to people's work.

Description

technical field [0001] The invention relates to the field of new technology for the synthesis of the agricultural herbicide acifluorfen, in particular to a synthesis process of the technical compound acifluorfen. Background technique [0002] Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, a class of substances used to eliminate or inhibit plant growth. Among them, sodium chlorate, borax, arsenate and trichloroacetic acid have a deadly effect on any kind of plants, and their effects are affected by three factors: herbicides, plants and environmental conditions. According to the function, it can be divided into killing and selective herbicides. Most of the selective herbicides, especially the derivatives of nitrophenol, chlorophenol or carbamic acid, are effective. The development of herbicides in the world is gradually stabilizing, mainly developing varieties with high efficiency, low toxicity, broad spectrum and low dosag...
