Abstract
The present invention relates to field of pesticide preparation, a kind of benzene-series solvent replacements sulfonated kerosene and its application in chlorpyrifos ec are disclosed.Sulfonated kerosene can replace benzene-series solvent common in chlorpyrifos ec well in formula of the present invention, and obtained missible oil has preferable stability and dispersiveness.The present invention reduces the usage amount of benzene, toluene and dimethylbenzene in emulsifiable concentrates for agricultural chemicals, murder by poisoning of the benzene-series solvent to people and the pollution to environment are reduced, meanwhile, reduce the production cost of missible oil.
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 chlorpyrifos ec.
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
The emulsifiable concentrate formulation of benzene-series solvent is replaced with sulfonated kerosene and its in chlorpyrifos ec the invention provides a kind of
Application, obtained missible oil has preferable stability and dispersiveness, so as to replace solvent there is provided one kind, reduce missible oil into
This, and reduce the harm that organic solvent is caused to environment and human health.
Emulsifiable concentrate formulation of the present invention is to substitute chlopyrifos active compound after the dissolving of solvent sulfonated kerosene, is added appropriate
Emulsifying agent mixed so that obtain a kind of stability and dispersiveness preferably missible oil.
In certain embodiments preferably, of the present invention substitute the weight that solvent sulfonated kerosene accounts for the emulsifiable concentrate formulation
Percentage is 25% ~ 55%, and the percentage by weight that emulsifying agent accounts for the emulsifiable concentrate formulation is 10% ~ 20%, and chlopyrifos active compound accounts for the breast
The percentage by weight of oil formula is 35% ~ 55%.
It is preferred that, emulsifying agent of the present invention is farm chemical emulgent monomer 500#, 1601,1602, OP-7,600,600-
1st, 600-2,600-3, BY-110, BY-112, BY-120, BY-130, BY-140,400,403, one kind in emulsification agent or
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 40%.
Result of the test shows that the organic solvent of patent of the present invention substitutes solvent sulfonated kerosene, can well dissolve and poison with poison
Tick active compound, and there is preferable stability and dispersiveness with the missible oil obtained after emulsifying agent mixing, so as to reduce in missible oil
The usage amount of organic solvent, adds the security of food, and reduces pollution level of the organic solvent to environment.
It is an object of the invention to provide a kind of emulsifiable concentrate formulation for substituting organic solvent in chlorpyrifos ec, by above-mentioned replacement
Solvent sulfonated kerosene, emulsifying agent and chlopyrifos active compound are mixed.
The beneficial effects of the invention are as follows：The replacement solvent sulfonated kerosene of patent of the present invention, chlopyrifos can be dissolved well
Active compound, and there is preferable stability and dispersiveness with the missible oil obtained after emulsifying agent mixing, so as to reduce benzene in missible oil
The usage amount of range of solvents, and reduce the murder by poisoning to people and the pollution of environment.
