Description
Technical field
The invention belongs to herbicide field more particularly to the preparation methods of a kind of tribenuron-methyl and dimethyl tetrachloride microemulsion.
Background technology
Tribenuron-methyl, also known as broad-leaved is quiet, is slightly soluble in water and organic solvent, is selective inner-adsorption conduction-type herbicide, can be miscellaneous
Root, the leaf of grass are absorbed, and conducted in plant body, by inhibiting the activity of acetolactate synthestase, so as to influence branched-amino
The biosynthesis of acid shows as growing point necrosis, vein chlorosis after hazard of plant, and plant growth is heavily suppressed, downgrades, most
Whole complete stool is withered, and susceptible weeds stop growing immediately after absorbing medicament, and dead after 1-3 weeks, control object is mainly various 1 years
Raw broad leaved weed.Dimethyl tetrachloride is colourless crystallization, belongs to lower toxicity phenoxy carboxylic acid selective herbicide, and there is stronger interior inhale to pass
The property led, is mainly used for cauline leaf process after seedling, and medicament passes through cuticula and cytoplasma membrane, each several part is finally transmitted to, in different portions
Position inhibits nucleic acid metabolism and the synthesis of protein in plant tip, makes growth to nucleic acid and the synthetically produced Different Effects of protein
Point stops growing, young leaflet tablet not tensible, until photosynthesis cannot be normally carried out；The medicament of plant lower part is transmitted to,
Make the synthesis increase for the nucleic acid and protein that plant stem organizes, promote abnormal cell division, the tip of a root expands, and loses and absorbs nutrient
Ability, cause cane distortion, deformity, screen casing block, bast destroy, organic matter transport be obstructed, it is normal so as to destroy plant
Viability, ultimately result in Plant death, available for most of annual broadleaf weed is prevented and kill off, also have to grassy weed anti-
Effect.Tribenuron-methyl and dimethyl tetrachloride compounding have a synergistic effect, the good dispersion in water of the product after compounding, and activity is high, to various miscellaneous
Careless permeability is strong, and adhesive force is good, can effectively prevent and kill off various annual broadleaf weeds, also has to grassy weed and certain prevents and kill off effect
Fruit.
The content of the invention
Present invention mainly solves the problem of be to provide a kind of tribenuron-methyl and dimethyl tetrachloride microemulsion, prepare what the product used
Raw material is by weight ratio：Tribenuron-methyl water dispersible granule 10-11%, dimethyl tetrachloride 4-5%, benzene sulfonic acid sodium salt 2%, ether 13%, water
70%。
The technical solution adopted by the present invention is：
（1）First the ether of formula ratio is added in the first agitator tank, starts to stir under room temperature, adds in formula ratio while stirring
Dimethyl tetrachloride, 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 25-30/
Point, the benzene sulfonic acid sodium salt of formula ratio is added in while stirring, stirs to benzene sulfonic acid sodium salt and the tribenuron-methyl water of formula ratio is added in after all dissolving
Dispersible granule；The rotating speed of blender in fast agitator tank is heightened as 190-200 revs/min, will slowly be dissolved in the dimethyl tetrachloride of ether
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 dimethyl tetrachloride is 80%.
Step（1）, step（2）The room temperature is 0-38 DEG C.
The beneficial effects of the invention are as follows：The preparation method of a kind of tribenuron-methyl and dimethyl tetrachloride microemulsion is provided, the production
The advantages of method is：It is simple for process, environmental pollution is small, the reaction time is short, reaction condition is mild, tribenuron-methyl and dimethyl tetrachloride compounding
There is a synergistic effect, the good dispersion in water of the product after compounding, activity is high, strong to various weeds permeability, and adhesive force is good, can have
Effect prevents and kill off various annual broadleaf weeds, also there is certain preventive effect to grassy weed.
