Description
Technical field
The present invention relates to field of pesticide preparation, particularly relate to a kind of benzene-series solvent replacements sulfonated kerosene and its
Application in Cyhalothrin missible oil.
Background technology
Missible oil refers to active compound（Crude oil or former powder）Dissolve by a certain percentage in organic solvent, add a certain amount of agriculture
Medicine emulsifier special and other auxiliary agents, a kind of oily liquids for the homogeneous phase transparent being formulated.After typically being diluted with a large amount of water, energy
The enough emulsion as stabilization.Emulsifying agent in missible oil is molten mostly using nonionic and the mixture of anion surfactant
Agent uses benzene,toluene,xylene or mixed benzene etc. mostly, in addition also with alcohols solvents such as hexone class and isopropanols.
Missible oil is the main formulations of pesticide of current China, and solvent is indispensable important set in such formulation
Point, wherein with benzene-series solvent（Benzene,toluene,xylene or mixed benzene class）Based on.The benzene-series solvent used in missible oil is inflammable easily
Quick-fried and poisonous, these organic solvents are easily polluted to environment, and the producer and the healthy of user are existed
Potential hidden danger.Therefore, the use of benzene-series solvent is increasingly restricted.
Because sulfonated kerosene has, small toxicity, Environmental compatibility are good, resource is sufficient, low cost and other advantages, meet following agriculture
Pharmaceutically dosage form develops the requirement to solvent, therefore can substitute benzene-series solvent in traditional pesticidal preparations.
The content of the invention

A variety of, preferably emulsifying agent 500#, 1601, OP-7, the mixture of emulsification agent, more preferably emulsifying agent mixture account for the missible oil
The percentage by weight of formula is 15%.
It is preferred that, emulsification agent of the present invention is polyoxyethylene alkylphenol ether compound, its to be non-ionic,
Thick pale yellow shape liquid, pH is 6 ~ 7, and 60 ~ 80 DEG C of 1% distilled water solution oil drop is soluble in water, in acid, alkali, oxidant
It is all very stable, it is very strong to animals and plants and mineral greasy dirt cleansing power with functions such as emulsification, purification, de-oiling, decontaminations, in printing and dyeing
Mainly as dye leveller and refining agent in industry, make one of component of finish in synthetic fibers, in addition to emulsifiability is shown, also
With antistatic effect.
It is preferred that, the percentage by weight that replacement solvent sulfonated kerosene of the present invention accounts for the emulsifiable concentrate formulation is 82.5%.
Result of the test shows that the organic solvent of patent of the present invention substitutes solvent sulfonated kerosene, and trifluoro can be dissolved well
Cypermethrin technical material, and there is preferable stability and dispersiveness with the missible oil obtained after emulsifying agent mixing, so as to reduce
The usage amount of benzene-series solvent in missible oil, and reduce pollution level of the benzene-series solvent to environment.
It is an object of the invention to provide a kind of emulsifiable concentrate formulation for substituting organic solvent in Cyhalothrin missible oil, by upper
Replacement solvent sulfonated kerosene, emulsifying agent and Cyhalothrin active compound is stated to mix.
The beneficial effects of the invention are as follows：The replacement solvent sulfonated kerosene of patent of the present invention, trifluoro chlorine can be dissolved well
Cyano chrysanthemate active compound, and there is preferable stability and dispersiveness with the missible oil obtained after emulsifying agent mixing, so as to reduce breast
The usage amount of benzene-series solvent in oil, and reduce the murder by poisoning to people and the pollution of environment.
