Abstract
Relating to the field of pesticide preparations, the invention discloses a benzene series solvent substitute sulfonated kerosene and application thereof in cyhalothrin emulsifiable concentrate. The sulfonated kerosene with the formula provided by the invention can well replace the benzene series solvent common in cyhalothrin emulsifiable concentrate, and the obtained emulsifiable concentrate has good stability and dispersibility. According to the invention, the dosage of benzene, toluene and xylene in pesticide emulsifiable concentrate can be reduced, the toxicity of benzene series solvents to human and pollution to the environment are reduced, and at the same time, the production cost of emulsifiable concentrate is lowered.
Description
Technical field
The present invention relates to field of pesticide preparation, relate to a kind of benzene-series solvent replacements sulfonated kerosene and the application in Cyhalothrin missible oil thereof specifically.
Background technology
Missible oil refers to and is dissolved in organic solvent by a certain percentage by former medicine (crude oil or former powder), then adds a certain amount of agricultural chemicals emulsifier special and other auxiliary agents, the oily liquids of formulated a kind of homogeneous phase transparent.After the large water gaging dilution of general use, stable emulsion can be become.Emulsifier in missible oil uses the mixture of nonionic and anion surfactant mostly, and solvent adopts benzene,toluene,xylene or mixed benzene etc. mostly, also uses the alcohols solvents such as hexone class and isopropyl alcohol in addition.
Missible oil is the main formulations of pesticide of current China, and solvent is important component indispensable in such formulation, wherein based on benzene-series solvent (benzene,toluene,xylene or mixed benzene class).The benzene-series solvent used in missible oil is inflammable and explosive, and poisonous, and these organic solvents easily to environment, and also exist potential hidden danger to the producer and the healthy of user.Therefore, the use of benzene-series solvent is more and more restricted.
Because sulfonated kerosene has, toxicity is little, Environmental compatibility good, resource is sufficient, low cost and other advantages, meets the requirement of pesticide in future formulation development to solvent, therefore can substitute benzene-series solvent in traditional pesticidal preparations.
Summary of the invention
The invention provides a kind of sulfonated kerosene and replace the emulsifiable concentrate formulation of benzene-series solvent and the application in Cyhalothrin missible oil thereof, the missible oil obtained has good stability and dispersiveness, thus provide a kind of replacement solvent, reduce missible oil cost, and decrease the harm that benzene-series solvent causes environment and human health.
Emulsifiable concentrate formulation of the present invention is after being dissolved by former for Cyhalothrin medicinal alternative solvent sulfonated kerosene, then adds appropriate emulsifier and mix, thus obtains a kind of stability and the good missible oil of dispersiveness.
In certain embodiments as preferred, the percentage by weight that alternative solvent sulfonated kerosene of the present invention accounts for described emulsifiable concentrate formulation is 75% ~ 88%, the percentage by weight that emulsifier accounts for described emulsifiable concentrate formulation is 10% ~ 20%, and the percentage by weight that the former medicine of Cyhalothrin accounts for described emulsifiable concentrate formulation is 2% ~ 5%.
Preferably, emulsifier of the present invention be farm chemical emulgent monomer 500#, 1601,1602, OP-7,600,600-1,600-2,600-3, BY-110, BY-112, BY-120, BY-130, BY-140,400,403, one or more in emulsification agent, be preferably emulsifier 500#, 1601, OP-7, emulsification agent mixture, being more preferably the percentage by weight that emulsifier mixture accounts for described emulsifiable concentrate formulation is 15%.
Preferably, emulsification agent of the present invention is polyoxyethylene alkylphenol ether compound, it is nonionic, thick pale yellow shape liquid, pH is 6 ~ 7, the distilled water solution oil drop of 1% 60 ~ 80 DEG C, soluble in water, all very stable in acid, alkali, oxidant, there is the functions such as emulsification, purification, de-oiling, decontamination, to animals and plants and mineral greasy dirt cleansing power very strong, mainly as dye leveller and refining agent in printing and dyeing industry, one of component making finish in synthetic fibers, except display emulsifiability, also has antistatic effect.
Preferably, the percentage by weight that alternative solvent sulfonated kerosene of the present invention accounts for described emulsifiable concentrate formulation is 82.5%.
Result of the test shows, the organic solvent of patent of the present invention substitutes solvent sulfonated kerosene, the former medicine of Cyhalothrin can be dissolved well, and with the missible oil obtained after emulsifier mixing has good stability and dispersiveness, thus decrease the usage amount of benzene-series solvent in missible oil, and reduce the pollution level of benzene-series solvent to environment.
The object of the present invention is to provide the emulsifiable concentrate formulation of organic solvent in a kind of alternative Cyhalothrin missible oil, mixed by above-mentioned alternative solvent sulfonated kerosene, emulsifier and the former medicine of Cyhalothrin.
The invention has the beneficial effects as follows: the alternative solvent sulfonated kerosene of patent of the present invention, the former medicine of Cyhalothrin can be dissolved well, and with the missible oil obtained after emulsifier mixing has good stability and dispersiveness, thus decrease the usage amount of benzene-series solvent in missible oil, and the pollution of the murder by poisoning reduced people and environment.
