Definitions
- the present invention relates to a novel dosage form of the insecticide, and more particularly to a water-soluble granule containing chlorfenapyr and a process for the preparation thereof. Background technique
- Bipropiononitrile is a pyrrole insecticide and acaricide developed by American Cyanamide Company. Its chemical name is 4-bromo-2-(4-chlorophenyl)-1-ethoxymethyl-5-trifluoromethylpyrrole. 3-nitrile, also known as depletion, insect nitrile, pyrrolamine, AC303630, etc.
- the drug has the functions of contact and stomach toxicity, and its action mechanism is unique. It has a long-lasting effect and has good control effect on various pests and pests on vegetables, cotton, fruits, soybeans, etc., and has low toxicity to humans and animals. Years of field efficacy tests have proven that chlorfenapyr is a good variety with popularized application value and development prospects.
- Water emulsion (EW), microemulsion (ME), aqueous suspension (SC), water-soluble liquid (SL), etc. are representative new forms of water-based preparations.
- the common feature is that water replaces a large amount of organic solvents and reduces solvents. Waste and pollution, reduce the toxicity of the preparation, improve safety, is a new dosage form to replace emulsifiable concentrate. 2.
- the solid preparation is granulated.
- the powder preparation is granulated to avoid dust pollution, and packaging is also the direction of dosage form research.
- Water dispersible granules (WDG) are representative granules.
- the dosage form has a granular appearance and is rapidly disintegrated and dispersed in water when used, thereby forming a highly suspended dispersion system for use in spray application.
- the preparation content and suspension rate are much higher than wettable granules, good fluidity, no dust pollution, convenient packaging, storage and transportation. It is a new dosage form integrating the advantages of wettable powder, suspoemulsion and granules. However, these dosage forms do not combine the advantages of both, but also manifest. Summary of the invention
- the object of the present invention is to overcome the disadvantages of the prior art described above and to provide a substitute for a large amount of organic solvent with water. It reduces the waste and pollution of the solvent, reduces the toxicity of the preparation, improves the safety, and has a granular appearance.
- the water-soluble granules (WSG) containing chlorfenapyr and the preparation method thereof are rapidly disintegrated and dispersed in water when used.
- a water-soluble granule of chlorfenapyr mainly made up of the following weight percentages:
- Emulsifier 1 ⁇ 30%
- Dispersing agent 1 ⁇ 10%
- wetting agent 1 ⁇ 5 %
- Binder 2 ⁇ 4% ;
- Stabilizer 1 ⁇ 3 %
- the balance is a filler.
- the chlorfenapyr water-soluble granule of the present invention wherein the emulsifier is selected from the group consisting of alkylphenol ethoxylates, benzylphenol ethoxylates and the like, fatty alcohol ethoxylates and the like or sorbitol fatty acids One or a mixture of esters and their ethylene oxide adducts.
- the chlorfenapyr water-soluble granule of the present invention wherein the dispersing agent is selected from the group consisting of alkylnaphthalene sulfonate, bisnaphthalenesulfonate formaldehyde condensate or sodium lignosulfonate.
- the alkylnaphthalenesulfonate may be a pull-off powder BX, a pull-up powder AC or the like; and the bisnaphthalenesulfonate formaldehyde condensate may be a dispersant N, a dispersant NN0 or the like.
- the chlorfenapyr water-soluble granule of the present invention wherein the wetting agent is selected from the group consisting of alkyl benzene sulfonate, fatty amide N-methyl sulfonate, alkyl aryl oxyethylene ether sulfate or Two mixtures.
- the chlorfenapyr water-soluble granule of the present invention wherein the binder is one or a mixture of two selected from the group consisting of ⁇ -cyclodextrin, polyvinyl alcohol, and methyl cellulose.
- the chlorfenapyr water-soluble granule of the present invention wherein the stabilizer is selected from the group consisting of sodium benzoate and glucose.
- the chlorfenapyr water-soluble granule of the present invention wherein the filler is selected from the group consisting of hydrogencarbonate, anhydrous citric acid, maltose, and anhydrous One or two mixtures of sodium sulfate.
- the preparation method of the chlorfenapyr water-soluble granule of the invention is as follows: the substance is homogenized, kneaded and extruded granulated according to the ratio, dried under vacuum at 65 to 75 ° C for 1 to 2 hours, sieved, sieved The product is packaged after testing; the product that cannot pass through the sieve repeats the above steps.
- the specific preparation method comprises the following steps:
- the water-soluble granules of the invention meet the requirements of the current development trend of pesticides by replacing the organic solvents such as xylene, methanol and toluene with the aqueous solvent, the solid granulation or tableting of the drug form, the high content of the pesticide and the functionalization.
- the adhesive is embedded in the original drug and the stability and anti-oxidation effect of the stabilizer, so that the anti-radiation and illumination ability of the original drug is improved, and the shelf life of the drug is prolonged; the bicarbonate and citric acid in the filler can effervescent The role of the agent to promote the dissolution of the granules.
- the water-soluble granule of the invention can be quickly dissolved in water, has high dispersing rate, has no floating and sinking phenomenon, has a large amount of organic solvent replaced by water, reduces solvent waste and pollution, reduces preparation toxicity, improves safety, and has appearance as granules. It has the characteristics of rapid disintegration and dispersion in water, convenient transportation and storage, and long shelf life.
- the preparation method is simple, easy to operate and control.
- the invention contains no or only a small amount of toxic and flammable aromatic hydrocarbon solvents, thereby avoiding flammable and explosive phenomena during production, storage and transportation.
- This dosage form has no unpleasant toxic odor, is less irritating to the eyes, reduces environmental pollution, and greatly improves the safety of production, storage, transportation and users. Therefore, after industrialization, not only the economic benefits are obvious, but also the development of high-tech green pesticide technology is promoted. It has obvious social benefits for promoting environmental protection and is the research direction of sustainable development. detailed description
