Abstract
The invention discloses 20% fenvalerate-omethoate emulsifiable oil and a preparation method thereof. The preparation method comprises the following steps: according to weight percentage, weighing raw materials of 15-20% of omethoate crude oil, 2-4% of 92% fenvalerate crude oil, 6-10% of surfactant and the balance of pure benzene; firstly, melting the 92% fenvalerate crude oil; secondly, adding the pure benzene into a reaction kettle, slowly adding the omethoate crude oil and adding the 92% fenvalerate crude oil; and finally, adding the surfactant, uniformly stirring for 35-45 minutes, standing, discharging and packaging to obtain a finished product. The preparation method has the characteristics of high yield, high product purity, low cost, mild reaction conditions, simplicity in operation, and the like; the yield is more than 95%; and the insecticidal effect is obvious.
Description
Technical field
The present invention relates to 20% cyanogen, penta missible oil of omethoate and preparation method thereof, belong to pesticide field.
Background technology
Omethoate, O, O-dimethyl-S-[2-(methylamino)-2-oxoethyl] thiophosphate, pure article are colourless transparent oil liquid; Relative density 1.32, about 135 ℃ of boiling point has decomposition; Refractive index 1.4987 can be miscible with multiple solvents such as water, ethanol and hydro carbons, is slightly soluble in ether; Be dissolved in benzinum hardly, crude oil is pale yellow to the yellow transparent oily liquids, and missible oil of omethoate is the pale yellow oily liquid body.
Omethoate has very strong action of contace poison to insect and mite class, especially to some to Rogor develop immunity to drugs ground aphid, virulence is higher, still can keep stronger toxicity at hypothermic phase; Be mainly used in the good medicament of the multiple aphid of control banana, tortrix moth, prodenia litura, flower thrips and lace bug etc., the insecticidal action performance of hypothermic phase omethoate is faster than Rogor.
Omethoate also has very strong inner sucting killing insect effect, can be by in the stem of plant, the leaf inspiration plant body, and can be sent to the soup portion that is not sprayed onto; And the insect of harm in the above is poisoned to death, therefore, when using omethoate; Can adopt the method dispenser of stem brush; Omethoate belongs to high-toxic pesticide, but it is difficult from dermal osmosis entering human body, and is little with the contact toxicity difference of Rogor.
Summary of the invention
For deficiency and the defective of alleviating prior art; The object of the present invention is to provide a kind of 20% cyanogen, penta missible oil of omethoate and preparation method thereof; Characteristics such as the present invention has the yield height, product purity is high, cost is low, reaction condition is gentle, simple to operate; And yield of the present invention reaches more than 95%, and insecticidal effect is obvious.
The present invention adopts following technical scheme to achieve these goals:
20% cyanogen, penta missible oil of omethoate, the percentage by weight of its constitutive material is: omethoate crude oil 15-20%, 92% cyanogen, penta crude oil 2-4%, surfactant 6-10%, purified petroleum benzin surplus.
20% cyanogen, penta missible oil of omethoate, the percentage by weight of its constitutive material is: omethoate crude oil 17%, 92% cyanogen penta crude oil 3%, surfactant 8%, purified petroleum benzin surplus.
The preparation method of described 20% cyanogen, penta missible oil of omethoate may further comprise the steps:
(1) percentage by weight by constitutive material takes by weighing raw material, earlier 92% cyanogen, penta crude oil is melted;
(2) purified petroleum benzin is added in the agitated reactor, slowly add omethoate crude oil then, add 92% cyanogen, penta crude oil in the step (1) again;
(3) add surfactant at last, stirred 35-45 minute, leave standstill, discharging is packaged to be finished product.
20% cyanogen, penta missible oil of omethoate is characterized in that: described surfactant is triphen ethyl phenol APEO, APES succinate sulfonate, OPEO or APES polyethenoxy ether.
Beneficial effect of the present invention:
The present invention has characteristics such as yield height, product purity are high, cost is low, reaction condition is gentle, simple to operate, and yield of the present invention reaches more than 95%, and insecticidal effect is obvious.
Embodiment
Embodiment 1:20% cyanogen, penta missible oil of omethoate, the percentage by weight of its constitutive material is: omethoate crude oil 17%, 92% cyanogen penta crude oil 3%, surfactant 8%, purified petroleum benzin surplus.
