Description
Technical field
The present invention relates to a kind of production method of agricultural chemicals, be specifically related to a kind of nitrile bacterium azole suspending agent composition and production method thereof.
Background technology
Nitrile bacterium azoles is the systemic fungicide with protection and therapeutic action, characteristics such as it has efficiently, wide spectrum, low toxicity, and to Ascomycotina, Basidiomycotina, the microbial multiple diseases of Deuteromycotina cause of disease has good preventing and result of treatment.Can be widely used in: the powdery mildew of wheat, rust, smut; The scab of pears, apple, powdery mildew, brown spot, graywall; Melon powdery mildew; The leaf spot of banana and peanut; The powdery mildew of grape; The powdery mildew of vegetables and flowers, rust etc.Characteristics such as it is few to have consumption, and the lasting period is long, and is safe in utilization, good market prospects.The molecular formula of this active ingredient: C
15H
17ClN
4English common name: myclobutanil; CAS accession number: 88671-89-0.The own nitrile of chemical name: 2-(4-chlorphenyl)-2 (1H-1,2,4-triazol-1-yl methyl).
Structural formula:
Physicochemical property:
Pure product are white crystal, fusing point: 68～69 ℃, boiling point: 202～208 ℃/1mmHg, vapour pressure: 0.213m Pa (25 ℃) is insoluble to aliphatic hydrocarbon, is dissolved in most of organic solvents, and industrial goods are the dark brown solid, fusing point: 63～68 ℃
Suspending agent is that what to be grown up in recent years is the water base formulation of disperse phase with water, and R﹠D institution, enterprise relatively paid close attention to the research and development of this formulation both at home and abroad in recent years.Suspending agent (SuspensionConcentrate, SC) be insoluble or the former medicine that is slightly soluble in water by some auxiliary agent, be scattered in the water the stable liquid-solid attitude system that form the tiny higher suspension of a kind of particle, can flow more equably by the wet method ultramicro grinding.Suspending agent normally is made up of effective ingredient, dispersant, thickener, antiprecipitant, defoamer, antifreezing agent and water etc.The content of effective ingredient is generally 5%-50%.Average grain diameter is generally about 3 μ m.The dispersiveness of suspending agent and plate-out ability are all relatively good, the suspensibility height, and the ability that sticks to the plant corpus surface is more intense, resistance of rainwater washing against, thereby drug effect significantly and also compares lastingly than wetting powder.
Agricultural chemicals Water-borne modification formulation be with water as dispersion medium, pesticide original medicine (solid or oily liquid) makes it to suspend by the effect of dispersant or emulsifier and other auxiliary agent or emulsification is dispersed in the water.Compare with missible oil, reduced a large amount of organic solvents; Compare with wettable powder, then do not have dust and disperse; Toxicity and excitant to people and animals are all lower; And can alleviate poisoning to crop; Can be because of organic solvent does not cause burning in storage in the transportation yet, the higher suspending agent of safety be water as disperseing the suitable auxiliary agent of addition, process through special process.This formulation overcomes the harm that missible oil with an organic solvent brings to environment in a large number, has also overcome some shortcomings of pulvis.So suspending agent is a kind of optimal selection that substitutes traditional missible oil and pulvis.
At present, domestic nitrile bacterium azoles preparation all is missible oil and wetting powder; Face following technical difficulty if adopt prior art that the nitrile bacterium azoles among the application is made agricultural suspending agent: can't make the bin stability of solution reach standard.This also is the greatest difficulty that present suspending agent faces.After many products were deposited a period of time, the layering caking was serious, and redispersibility is poor, and suspensibility descends.Severe patient is difficult to pour out from container, uses to the user and brings difficulty.Therefore at present also not occurring the suspending agent that bulk myclobutanil makes on the domestic market appears on the market.
Summary of the invention
The object of the invention is to overcome above-mentioned technical difficulty, provides a kind of nitrile bacterium azoles is made the production method of agricultural suspending agent, produces to have stable performance, and suspensibility is good, the nitrile bacterium azole suspending agent of characteristics such as reliable in quality.Use this method and suitable industrialized production, stay-in-grade prescription is developed the novel form that contains nitrile bacterium azoles active ingredient: nitrile bacterium azole suspending agent composition so that avoid traditional emulsifiable concentrates for agricultural chemicals and wetting powder drawback in production, transportation, use and the influence that brings to ecotope.And the raising drug effect reduces agricultural cost.
From this purpose, the present invention has developed with water as dispersion medium, and pesticide original medicine (solid or oily liquid) makes it to suspend by the effect of dispersant or emulsifier and other auxiliary agent or emulsification is dispersed in the water, forms suspending agent.Suspending agent stable performance of the present invention.
