Abstract
The invention discloses a water dispersible granule of acetochlor and a preparation method thereof, and belongs to the field of new formulations of pesticide herbicides, in particular to a water dispersible granule of amide herbicide acetochlor, and a preparation method thereof. The water dispersible granule is characterized by comprising the following components by weight percent: 1 to 40 percent of acetochlor, 1 to 40 percent of emulsifier, 10 percent of dispersing agent, the balance being kaolin or other inert fillers.
Description
Technical field:
This belongs to pesticide herbicide novel form field, and what relate to is water dispersible granule of a kind of acetamide-group herbicides Acetochlor and preparation method thereof.
Background technology:
The chemical name of Acetochlor is 2 '-ethyl-6 ' methyl-N-(ethoxymethyl)-2-chloro acetanilide.
Its structural formula is:
Acetochlor is by the selectivity preemergence herbicide of U.S. Monsanto Company (Monsanto Co.) research and development, has obtained patent Ger.offer.2226593; 1542956; US3442945.This weed killer herbicide can be absorbed by the young shoot of weeds and young root, suppresses the protein synthesis of weeds and makes weeds death, and the lasting period can reach about 2 months in soil.Can be widely used in the weeding in various crop fields such as soybean, corn, cotton, peanut, potato, sunflower, rape, sesame, radish, sugarcane, orchard, paddy rice and pulse family, Cruciferae, Solanaceae, chrysanthemum and Umbelliferae.
Acetochlor is at first developed by Shenyang Chemical Engineering Inst and chemical plant, Kunshan, Jiangsu at home, present domestic have how tame former medicine manufacturer and preparation manufacturer.At present common in the formulation of Acetochlor registration is missible oil, wetting powder and aqueous emulsion.
Because the allotment of missible oil is comparatively simple, equipment is not had special requirement in common formulation, manufacturer is numerous.Acetochlor ec mainly adopts aromatic solvent to prepare at home and abroad.Aromatic solvent commonly used mainly contains benzene,toluene,xylene etc.These aromatic solvents have caused the serious environmental pollution problem, and missible oil manufacturer is in order to reduce the production cost of missible oil especially in recent years, and a large amount of methyl alcohol that use have caused serious destruction as the solvent of producing missible oil to environment on producing.Therefore use no or little the research direction that solvent has become the formulations of pesticide.
Water dispersible granule of acetochlor uses conventional inert filler to replace organic solvent, and the pollution of environment is significantly reduced.
Summary of the invention:
Content of the present invention is a kind of water dispersible granule of acetochlor and preparation method thereof
The active constituent content of water dispersible granule of the present invention is: 1-40%wt
Adoptable surfactant has anionic surfactant and nonionic surface active agent.The aliphatic alcohol sulfate that comprises Sulfates, alkylol polyoxyethylene groups ether sodium sulfate etc., the sodium alkyl sulfonate of Sulfonates, alkylbenzenesulfonate, alkylnaphthalene sulfonate, dialkyl succinylsuccinate sulfonate, monoalkyl phenyl polyoxyethylene groups ether succinic acid sulfonate, fatty alcohol ethylene oxide adduct sulfonate, alkylphenol formaldehyde condensation product ethylene oxide adduct sulfonate, fatty alcohol epoxy vinyl ether, alkylphenol-polyethenoxy base ether, the anhydrous sorbitol fatty acid ester, anhydrous sorbitol aliphatic acid polyethenoxy base ether, alkylphenol formaldehyde condensation product polyoxyethylene groups ether, sulfonation castor-oil plant alkoxide, quaternary ammonium salt derivative, the condensation product of oxirane and nonyl or octyl phenol is a main product or by esterification and oxirane, the alkalies and alkaline earth salt of sulfuric ester and sulfonic acid is as sulphonyl amber ester octyl group sodium in two ninth of the ten Heavenly Stems and such as the alkali of the macromolecule sulfonic acid derivative of sodium lignin sulfonate and calcium and carboxylate of the anhydrous sorbierite that the alkali salt condensation forms etc.That can give an example has farming breast No. 2000 series, petroleum sodium sulfonate, dodecyl sodium sulfates, draws back powder, ethoxylated dodecyl alcohol sodium sulfonate, tween series etc.
Adoptable carrier is generally mineral inert substance such as potter's clay, kaolin, bentonite, talcum powder, diatomite, white carbon etc.
The technical solution of water dispersible granule of the present invention is according to weight ratio, contains Acetochlor 1-40%, emulsifier 1-40%, the dispersant 10% of sulfocarbolate class, kaolin supplies 100%.
Specific embodiment
Following examples describe the present invention in detail, and embodiment mainly is for the present invention is described but not is used for limiting the present invention.
Embodiment 1
With 20 gram acetochlor tcs, 5 gram emulsifier add after stirring in agitator jointly after 10 grams stir behind the water again.The diatomaceous mixtures that add dispersants, 25 grams of kaolin, 20 grams of white carbons, 10 grams of 20 grams under the condition of stirring back that stirs adopts the method for extruder grain to carry out drying after the granulation to get final product.
Embodiment 1
With 30 gram acetochlor tcs, 10 gram emulsifier add after stirring in agitator jointly after 20 grams stir behind the water again.The mixture of dispersants that adds kaolin, 15 grams of white carbons, 5 grams of 40 grams under the condition of stirring back that stirs adopts the method for extruder grain to carry out drying after the granulation to get final product.
Claims (2)
1. water dispersible granule of acetochlor and preparation method thereof is characterized in that containing Acetochlor 1-40%, emulsifier 1-40%, dispersant 10%, kaolin or other inert filler and supplies 100%.
