Abstract
The invention discloses a kind of all you and dimethyl tetrachloride microemulsion, the products to belong to herbicide field；Preparing the raw material that the product uses includes：All your 7 8%, dimethyl tetrachloride 7 8%, ethyl alcohol 16%, benzene sulfonic acid sodium salt 2%, water 67%, by blending finished product under given conditions, the advantages of preparation method, is：Using common apparatus, simple for process, reaction condition is mild, pollution-free waste discharge；All you and dimethyl tetrachloride compounding have synergistic effect, the significant effect of management of weeds, which is higher than, is applied alone all you or dimethyl tetrachloride, product after compounding good dispersion in water, it is active high, strong to various weeds permeability, adhesive force is good, various annual broadleaf weeds can be effectively prevented and kill off, also there is certain preventive effect to grassy weed.
Description
Technical field
The invention belongs to herbicide field more particularly to a kind of all preparation methods of that and dimethyl tetrachloride microemulsion.
Background technology
All you are amides selective herbicide, and sterling is colourless liquid, is mainly absorbed by young shoot, are conducted upwards, suppression
Secondly the growth of young shoot and root processed, the protein synthesis of the main sprout inhibition seed of mechanism of action inhibit choline and penetrate into phosphatide, do
It disturbs lecithin to be formed, since the ability that grassy weed young shoot absorbs all thats is stronger than broad leaved weed, thus the medicine prevents and kill off grass family
The effect of weeds is good far better than broad leaved weed, all your emulsifiability, can mutually be mixed with many herbicides, is used in nonirrigated farmland work more
It is miscellaneous can effectively to prevent and kill off the broad-leaveds such as annual gramineous weeds and three-coloured amaranth, purslane such as eleusine indica, lady's-grass, green bristlegrass, cotton grass for object
Grass and cyperus iria, chufa, soil in 20-50 days lasting period.Dimethyl tetrachloride is colourless crystallization, belongs to the choosing of lower toxicity phenoxy carboxylic acid
Selecting property herbicide has stronger uptake and translocation, is mainly used for cauline leaf process after seedling, and medicament passes through cuticula and cytoplasm
Film is finally transmitted to each several part, in different parts to nucleic acid and the synthetically produced Different Effects of protein, inhibits core in plant tip
The synthesis of acid metabolic and protein, makes growing point stop growing, young leaflet tablet not tensible, until photosynthesis cannot be normal
It carries out；The medicament of plant lower part is transmitted to, makes the synthesis increase of nucleic acid and protein that plant stem organizes, promotes cell abnormal
Division, the tip of a root expand, and lose the ability for absorbing nutrient, cause cane distortion, deformity, and screen casing blocks, and bast destroys, organic matter
Transport is obstructed, and so as to destroy the normal viability of plant, ultimately results in Plant death.All you and dimethyl tetrachloride compounding have synergy
Effect, product after compounding good dispersion in water, activity is high, strong to various weeds permeability, and adhesive force is good, can effectively prevent and kill off
Various annual broadleaf weeds also have grassy weed certain preventive effect.
The content of the invention
Present invention mainly solves the problem of be to provide a kind of preparation method of all you and dimethyl tetrachloride microemulsion, produce the production
The raw material that product use is by weight ratio：All that 7-8%, dimethyl tetrachloride 7-8%, ethyl alcohol 16%, benzene sulfonic acid sodium salt 2%, water 67%.
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
Dimethyl tetrachloride, benzene sulfonic acid sodium salt, be stirred to react 0.4-0.5 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 30-40/
Divide, add in all thats of formula ratio while stirring；The rotating speed of blender in fast agitator tank is heightened as 210-220 revs/min, slowly
The mixture of ethyl alcohol, dimethyl tetrachloride, benzene sulfonic acid sodium salt is added in into 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 all thats is 80%, the purity of dimethyl tetrachloride is 75%.
Step（1）, step（2）The room temperature is 0-38 DEG C.
The beneficial effects of the invention are as follows：Provide a kind of all you and dimethyl tetrachloride microemulsion, the advantages of production method is：
It is simple for process, environmental pollution is small, the reaction time is short, reaction condition is mild, all you and dimethyl tetrachloride compoundings have synergistic effect, prevent and kill off
The significant effect of weeds is higher than being applied alone all you or dimethyl tetrachloride, the good dispersion in water of the product after compounding, and activity is high, to various
Weeds permeability is strong, and adhesive force is good, can effectively prevent and kill off various annual broadleaf weeds, also there is certain prevent and kill off to grassy weed
Effect.
