Description
Technical field
The invention belongs to weed killer herbicide field, relate in particular to the compound method of a kind of cyhalofop-butyl and the third careless amine complex microemulsion.
Background technology
Cyhalofop-butyl belongs to aryloxy group phenoxy propionic acid class weed killer herbicide, has another name called a thousand pieces of gold, and molecular formula is C20H20FNO4, and molecular weight is 357.4, former medicine outward appearance is white crystalline solid, and proportion is 1.2375,363 ℃ of boiling points, fusing point 48-49 ℃, dissolves in most organic solvents, water insoluble.Cyhalofop-butyl is interior suction conductivity weed killer herbicide, blade and leaf sheath by weeds absorb, phloem conduction, accumulate the meristem zone in weeds, resist acetyl-CoA carboxylase, fatty acid is synthesized and stop, the growth division of cell can not normally be carried out, film systems etc., containing fat structural deterioration, finally cause weeds dead.Controlling object, to paddy rice high safety, to moleplant seed, barnyard grass special efficacy, efficient to above the average age for marriage barnyard grass, hold concurrently and prevent multiple grassy weed simultaneously, as Paspalum distichum, lady's-grass, green foxtail, eleusine indica, amur foxtail etc. more than 30, plant grassy weed, can be used in rice seedling bed, live field, transplant field and seedling throwing field, cyhalofop-butyl degraded in soil and in rice field is rapid, to succession crop and rice safety.The third careless amine, claim again ten safeners, processing formulation is 30% missible oil, and effective ingredient is every 1 liter and contains 300 grams of the third careless amine, the third careless amine is selective herbicide before the bud of amide-type rice field, can to a leaf, wholeheartedly with interior barnyard grass preventive effect, can reach more than 95% safely for live field and rice seedling bed safe due to it, user can reduce seeding quantity, the spending of saving seed has reduced the sandwich barnyard grass to paddy rice underproduction maximum, for increasing production of rice has been laid reliable basis simultaneously; The third careless amine is except weeds gramineous are had good preventive effect, can also prevent and kill off multiple annual nutgrass flatsedge and broadleaf weed, as Monochoria vaginalis, difformed galingale herb, needle spikesedge herb, Eclipta prostrata, mexicana, Procumbent Falsepimpernel, false loosestrife, firefly Lin, cyperus iria etc., knotgrass, water purslane, four Ye Ping etc. are also had to double controlling and inhibitory action, remarkable to difficult anti-weeds preventive effects such as moleplant seeds, lasting period 30-50 days, substantially can control nursery period overall process weeds, and easy to use, after can directly diluting, with sprayer, be sprayed on seedling bed, also can mix fine earth, be spread on seedling face.Cyhalofop-butyl and the third careless amine is composite a synergistic effect, by above-mentioned two kinds of weed killer herbicides and auxiliary material composite after, the effect of preventing and kill off paddy field weed is significantly higher than alone cyanogen fluorine grass or the third careless amine, herbicidal effect strengthens greatly.
Summary of the invention
The problem that the present invention mainly solves is to provide the production method of a kind of cyhalofop-butyl and the third careless amine complex microemulsion, producing this product, to take cyhalofop-butyl, the third careless amine, toluene cyclohexanone, styrene, ethoxylated dodecyl alcohol sodium sulfonate, water be raw material, blending by under given conditions makes finished product, the advantage of this production method is: use common apparatus, technique is simple, reaction condition is gentle, pollution-free waste discharge, good product quality.The raw material weight proportioning of producing this product use is: cyhalofop-butyl 8-9%, the third careless amine 5-6%, toluene cyclohexanone 5-6%, styrene 12-13%, ethoxylated dodecyl alcohol sodium sulfonate 5-6%, surplus are water.
The present invention can be achieved through the following technical solutions:
