Abstract
The invention discloses a kind of tribenuron-methyl and quinclorac microemulsion, which belongs to herbicide field；It is raw material to produce the raw material that the product uses to include tribenuron-methyl water dispersible granule 10 11%, quinclorac 4 5%, ethyl alcohol 12%, water 73%, and by blending finished product under given conditions, the advantages of production method is：Using common apparatus, simple for process, reaction condition is mild, pollution-free waste discharge；Tribenuron-methyl and quinclorac compounding have synergistic effect, and after above-mentioned two kinds of herbicides and auxiliary material compounding, the effect of management of weeds greatly enhances, especially to above the average age for marriage barnyard grass special efficacy, available for paddy field and dry land.
Description
Technical field
The invention belongs to herbicide field more particularly to the preparation methods of a kind of tribenuron-methyl and quinclorac 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.Quinclorac also known as dichloro quinolinic acid, barnyard grass are died, and belong to the selectively stronger herbicide of hormone-type quinoline carboxylic acid, micro-
Water is dissolved in, is soluble in acetone, ethyl alcohol, ether, barnyard grass, ambatch, sesbania and other weeds can be effectively prevented and kill off, to the preventive effect of barnyard grass
Especially prominent, after two kinds of herbicides of tribenuron-methyl and quinclorac and auxiliary material compounding, the significant effect of anti-weeding, which is higher than, is applied alone benzene sulphur
Grand or quinclorac, the effect of management of weeds greatly enhance, especially to above the average age for marriage barnyard grass special efficacy.
The content of the invention
Present invention mainly solves the problem of be to provide the preparation method of tribenuron-methyl and quinclorac microemulsion a kind of, produce the production
The raw material that product use is by weight ratio：Tribenuron-methyl water dispersible granule 10-11%, quinclorac 4-5%, ethyl alcohol 12%, water 73%.
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
Quinclorac, 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/
Divide, add in the tribenuron-methyl water dispersible granule of formula ratio while stirring；The rotating speed for heightening blender in fast agitator tank is 190-200
Rev/min, the mixture of ethyl alcohol, quinclorac is slowly added in into high-speed stirred tank, be stirred to react 0.4-0.5 it is small when after obtain into
Product.
The present invention further technical solution be：
The purity of the tribenuron-methyl water dispersible granule is 65%, the purity of quinclorac 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 quinclorac microemulsion is provided, the producer
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 quinclorac compounding have increasing
Effect acts on, and after above-mentioned two kinds of herbicides and auxiliary material compounding, the effect of management of weeds greatly enhances, especially special to above the average age for marriage barnyard grass
Effect, also available for paddy field and dry land.
