Description
Technical field
The invention belongs to herbicide field more particularly to the preparation methods of a kind of tribenuron-methyl and prometryn microemulsion.
Background technology
It is quiet that tribenuron-methyl is also known as broad-leaved, is slightly soluble in water and organic solvent, is selective inner-adsorption conduction-type herbicide, can be by weeds
Root, leaf absorb, and conducted in plant body, by inhibiting the activity of acetolactate synthestase, so as to influence branched-chain amino acid
Biosynthesis, growing point necrosis, vein chlorosis are shown as after hazard of plant, plant growth is heavily suppressed, downgrades, finally
Complete stool is withered, and susceptible weeds stop growing immediately after absorbing medicament, and dead after 1-3 weeks, control object is mainly various annual
Broad leaved weed.Prometryn also known as prometon, flutter it is climing to the greatest extent, mow it is good, belong to triazine herbicide, be insoluble in water, be soluble in organic
Solvent, active ingredient are prometryn, there is rotten-egg odour, are stablized under weak base, weak acid and neutrallty condition, in strong acid, highly basic and height
It is easily decomposed under the conditions of temperature, to people, animal, fish, honeybee low toxicity, wettable powder appearance is light yellow or brownish red loose powder, is flutterred
Grass is interior suction selective herbicide only, can be absorbed and conduct through root and leaf, best to the Weed-control effect just sprouted, broad weed-killing spectrum,
Year annual gramineous weed can be prevented and kill off and broad leaved weed preventive effect is good, 20-70 days lasting period.Tribenuron-methyl and prometryn are answered
The microemulsion matched somebody with somebody has a synergistic effect, and product good dispersion in water, activity is high, powerful to grassy weed killing effect, to wealthy
Leaf weed control efficacy is preferable.
The content of the invention
Present invention mainly solves the problem of be to provide a kind of tribenuron-methyl and bentazone microemulsion, prepare the original that the product uses
Material be by weight ratio：Tribenuron-methyl water dispersible granule 8-9%, prometryn 6-7%, sodium alkyl sulfate 2%, ethyl alcohol 15%, water 68%.
The technical solution adopted by the present invention is：
（1）First the ethyl alcohol of formula ratio is added in the first agitator tank, starts to stir under room temperature, adds in formula ratio while stirring
Prometryn, be stirred to react 0.3-0.4 it is small when；
（2）First the water of formula ratio is added in high-speed stirred tank, starts to stir under room temperature, the rotating speed of blender turns for 20-30/
Point, the sodium alkyl sulfate of formula ratio is added in while stirring, stirs to sodium alkyl sulfate and the benzene sulphur of formula ratio is added in after all dissolving
Precititation dispersible granule；The rotating speed of blender in fast agitator tank is heightened as 190-200 revs/min, slowly flutters grass by be dissolved in ethyl alcohol
It is net to add in high-speed stirred tank, be stirred to react 0.4-0.5 it is small when after obtain finished product.
The present invention further technical solution be：
The purity of the tribenuron-methyl water dispersible granule is 75%, the purity of prometryn is 80%.
Step（1）, step（2）The room temperature is 2-35 DEG C.
The beneficial effects of the invention are as follows：A kind of tribenuron-methyl and prometryn microemulsion are provided, the advantages of production method is：
It is simple for process, environmental pollution is small, the reaction time is short, reaction condition is mild, tribenuron-methyl and prometryn compounding have synergistic effect, the production
Product good dispersion in water, activity is high, powerful to grassy weed killing effect, preferable to broad leaved weed preventive effect.
