Abstract
The invention discloses a kind of cyhalofop-butyl and clomazone complex microemulsion, which belongs to herbicide field；Prepare the raw material that the product uses includes by weight ratio：Cyhalofop-butyl 6 7%, clomazone 4 5%, dichloromethane 20%, sodium alkyl sulfate 1%, water 68%, 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, good product quality, and after above-mentioned two kinds of mixture of herbicides, higher than cyhalofop-butyl or clomazone is applied alone, anti-herbicidal effect greatly enhances the significant effect of anti-weeding.
Description
Technical field
The invention belongs to herbicide field more particularly to the preparation sides of a kind of cyhalofop-butyl and clomazone complex microemulsion
Method.
Background technology
Cyhalofop-butyl category aryloxyphenoxypropionic class herbicide also known as a thousand pieces of gold, dissolve in most organic solvents, do not dissolve in
Water, cyhalofop-butyl are uptake and translocation herbicides, are absorbed by the blade and leaf sheath of weeds, and bast conduction is accumulated in weeds
Meristem zone resists acetyl-CoA carboxylase, stops aliphatic acid synthesis, and the growth division of cell cannot be normally carried out, film
The structures containing fat such as system are destroyed, and finally result in weeds death, and controlling object is highly safe to rice, special to moleplant seed, barnyard grass
Effect, it is efficient to above the average age for marriage barnyard grass, while simultaneous anti-a variety of grassy weeds, it can be used in rice seedling bed, live streaming field, transplant field and seedling throwing field,
It degrades in the soil in rice field rapidly, to succession crop and rice safety.Clomazone is a kind of organic heterocyclic class selectivity seedling
Pro-herbicide also known as clomazone, appearance are light brown thick liquid, and solubility is 1.1 g/l in water, is soluble in acetone, second
Nitrile, chloroform, dichloromethane etc., clomazone category low toxicity herbicide selectivity herbicide before seedling stage are absorbed by the root of plant, young shoot,
Upward transporting diffuses to leaf portion through xylem, inhibits the synthesis of the chlorophyll and carrotene of sensitive plant, white seedling is formed, short
Dead in phase, the lasting period is long, and sustainable 6 months of the bioactivity of clomazone in the soil or more can prevent and kill off barnyard grass, green bristlegrass etc.
More than 30 plant weeds.Cyhalofop-butyl has synergistic effect with clomazone compounding, after above-mentioned two kinds of herbicides and auxiliary material compounding, anti-weeding
Significant effect higher than be applied alone cyanogen fluorine grass or clomazone, herbicidal effect greatly enhance.
The content of the invention
Present invention mainly solves the problem of be to provide a kind of cyhalofop-butyl and clomazone complex microemulsion, produce the product with
Cyhalofop-butyl, clomazone, dichloromethane, sodium alkyl sulfate, water are raw material, by blending finished product under given conditions,
Producing the raw material weight proportioning of soup processed that the product uses includes：Cyhalofop-butyl 6-7%, clomazone 4-5%, dichloromethane 20%, alkylsurfuric acid
Sodium 1%, water 68%.
The present invention can be achieved through the following technical solutions：
（1）First the dichloromethane of formula ratio is added in the first agitator tank, starts to stir under room temperature, the rotating speed of blender is 20
Turn -25 revs/min, sequentially add cyhalofop-butyl, the clomazone of formula ratio while stirring, 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 is 20 turn -30
Rev/min, the sodium alkyl sulfate of formula ratio is added in while stirring, is stirred to sodium alkyl sulfate and is all dissolved；It heightens in fast agitator tank
The rotating speed of blender is 190-200 revs/min, will slowly be dissolved in the cyhalofop-butyl of dichloromethane, clomazone adds 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 cyhalofop-butyl purity is 90%, the purity of clomazone is 85%.
Step（1）, step（2）The room temperature is 2-35 DEG C.
The beneficial effects of the invention are as follows：Provide a kind of cyhalofop-butyl and clomazone complex microemulsion, the advantages of this method
It is：It is simple for process, environmental pollution is small, the reaction time is short, reaction condition is mild, by above-mentioned two kinds of herbicides and auxiliary material compounding after,
The effect of anti-weeding greatly enhances.
