Description
Technical field
The present invention relates to a kind of emulsifiable concentrates for agricultural chemicals, more particularly to a kind of acetamiprid EC produced with environmentally friendly solvent and its life
Production method.
Background technique
Acetamiprid belongs to chlorination nicotine compound, is a kind of novel pesticide.Act on insect nerve system cynapse portion
The nicotinic acetylcholine receptor of position, the stimulation conduction of interference insect nervous system, causes nervous system path blockade, causes nerve
Transmitter acetylcholine synapses accumulation, it is final dead so as to cause insect paralysis.
Since Acetamiprid mechanism of action is different from current common insecticide, thus to organic phosphates, carbamates and
The resistant pest of author worm chrysanthemum esters has special efficacy, has efficiently to Semiptera, lepidoptera pest.The drug belongs to same with imidacloprid
Series, but its insecticidal spectrum is wider than imidacloprid, mainly has to the aphid on wheat, rice, melon, apple, citrus, tobacco
Preferable control efficiency.Due to Acetamiprid mechanism of action uniqueness, to agricultures such as organic phosphorus, carbamate and pyrethroids
The pest that drug kind develops drug resistance also has better effects.
The synthesis of Acetamiprid in two steps, the first step：2-vhloro-5-chloromethylpyridine and monomethyl amine reaction generate N- methyl -2-
Chloro- 5 methyl amine；Second step：Chloro- 5 methyl amine of N- methyl -2- and N- cyan ethyl ethylimidoote, which are reacted, is made Acetamiprid, by-product
Object is ethyl alcohol.Coproduct ethanol is not utilized effectively at present.There are many dosage forms of Acetamiprid, by the end of currently, containing pyridine
The registration dosage form of worm amidine effective component has missible oil, soluble liquid, microemulsion, wettable powder, soluble powder and water dispersion
Granula, wherein missible oil product accounts about 50%.The dosage form difference using effect of Acetamiprid is also different.
Since used number of devices is few and simple when being processed into cream preparation for Acetamiprid, simple production process is raw
The time for producing a collection of finished product is short, and yield in unit time is high, and power consumption is low, and ton manufacturing cost is low, and it is equal that liquid material is easy to mixing
Even, stable product quality, good emulsion stability, utilization rate of active components high using effect on crop is good, so most of
Enterprise is received.This method is easy the disadvantage is that using the poisonous and harmful organic solvent such as a large amount of benzene, toluene, DMF, methanol to production
Personnel and application personnel bring harm, have pollution to environment.
Summary of the invention
The purpose of the present invention：For the deficiency of existing Acetamiprid pesticide processing production process, provide a kind of environmentally protective
Acetamiprid EC and its production method, this method replace original benzene, toluene, DMF, methanol etc. to have with nontoxic etoh solvent
Malicious hazardous solvent, and then produce Acetamiprid emulsifiable concentrates for agricultural chemicals, simple process, non-pollution discharge in production are easy to implement.
Technical solution of the present invention：
A kind of acetamiprid EC pesticide, is made of the raw material of following weight percents：Acetamiprid raw medicine 2-10%, emulsifier 3-
8%, solvent make-up to 100%.
Preferably, the Acetamiprid raw medicine is 5%, emulsifier 5%, solvent 90%.
The emulsifier is agriculture breast 0203B；Solvent is industrial alcohol.
The production method of the acetamiprid EC pesticide first measures each ingredient by the weight percent, first by solvent
Half vacuum
It is pumped into modulation kettle, Acetamiprid raw medicine is then added, adds emulsifier, modulation kettle finally is added in remaining solvent,
It quickly stirs evenly, after sample examination is qualified, material is imported settling tank, stand, get to head tank after isolating mechanical admixture,
Upper canning line is distributed into inner wrapping to get product.
Beneficial effects of the present invention：
The present invention selects environmentally protective reproducible etoh solvent, instead of benzene used in the production of original acetamiprid EC, toluene,
The poisonous and harmful solvent such as DMF, methanol meets in current Agrochemicals trend and replaces poisonous and harmful solvent with nontoxic solvent
It is required that.
Invention formulation does not have unpleasant toxic odor, can be reduced environmental pollution, greatly improves the safety of production, user
Property；Simultaneous selection has the acetamiprid EC production technology of many advantages, and high production efficiency is at low cost, stable product quality.
The by-product second in Acetamiprid raw medicine synthesis process also can be used for industrial alcohol in the solvent that the present invention uses
Alcohol can make the by-product obtain rationally adequately utilizing in this way, improve the utility value of by-product.
Simple production process of the present invention, non-pollution discharge, implementation easy to spread.
Invention formulation is suitable for the prevention and treatment of various crop pest, such as wheat, rice, cucumber, cotton, pear tree, apple, mandarin orange
Tangerine, tobacco etc.；It is suitable for（1）Aphid, aleyrodid, the thrips of wheat；（2）The aphid of cotton, thrips, fleahopper silk worm；（3）The rice of rice
Plant hopper, thrips, leafhopper, weevil worm；（4）Aphid, the aleyrodid of vegetables；（5）Peanut, soybean, the aphid on rape；（6）On fruit tree
Aphid, pear sucker and Aleurocanthus spiniferus etc., the scope of application is wider.
Acetamiprid EC of the invention is significant to the insects preventive effect such as aphid, plant hopper, and low toxicity, and duration of efficacy is long, is
The substitute products of organophosphorus pesticide.The present invention replaces benzene, toluene, DMF, methanol etc. poisonous and harmful molten with nontoxic etoh solvent
After agent, obtained product is more advantageous on protecting field crop, the especially application to closed booth vegetable etc., due to etoh solvent
Be to crop and operating personnel it is nontoxic, can be reduced environmental pollution, be produce green agricultural product preferred insecticide.
Emulsifiable concentrates for agricultural chemicals of the invention is detected indices and meets HG/T 3756-2016 professional standard regulation.
