Fluroxypyrmuaj kev nyab xeeb siab rau pob kws, tab sis kev saib xyuas yuav tsum tau them rau lub sijhawm thov thiab ib puag ncig:
Daim ntawv thov tshuaj tua kab: Ua ntej 6-nplooj theem ntawm pob kws cog thiab 2-5 nplooj theem ntawm cov nroj tsuag, 50-66.7 milliliters ntawm 20% emulsion ib evkawj siv tau los tswj cov nroj tsuag xws li purslane, zaj radish, thiab amaranth.
Kev kho cov nroj tsuag nyuaj: Rau cov nroj tsuag malignant xws li Convolvulus thiab Me Convolvulus, qhov ntau npaum li cas yuav tsum tau nce mus rau 66.7 mus rau 100 milliliters ib evkawj. Piv txwv li, thaum tswj cov paj paj paj, cov nroj tsuag tuag tuaj yeem ncav cuag 95% 10 hnub tom qab thov.
Kev pheej hmoo ntawm ib puag ncig: Kev siv tshuaj tua kab hauv qhov kub thiab txias, cov av noo siab, lossis huab cua muaj zog tuaj yeem ua rau pob kws rau qhov chaw nyob. Qee hom pob kws qab zib yog rhiab rau nws thiab yuav tsum tsis txhob siv.
3. Vineyard thiab orchard: ib qho qauv ntawm cov tshuaj tsuag
Nyob rau hauv daim ntawv thov orchard, Clofepoxyacetic acid yuav tsum tau nruj me ntsis tshuaj tsuag kom tsis txhob raug mob:
Kev tswj cov nroj tsuag: 75-150 milliliters ntawm 20% emulsion ib daim av tuaj yeem siv los tswj cov kab dav dav xws li duckweed, foxtail nyom, Elsholtzia, thiab bluegrass. Piv txwv li, thaum tswj cov nroj tsuag hauv vineyards, kev tswj cov nyhuv nce mus txog 90% 15 hnub tom qab thov.
Kev sib xyaw thiab ua kom muaj txiaj ntsig zoo: Kev sib xyaw nrog 41% manganese dej tuaj yeem txhim kho kev tswj xyuas qhov nyuaj los kho cov nroj tsuag xws li hollow lotus noob zaub thiab fescue. Piv txwv li, siv 30ml ntawm 20% emulsion thiab 150ml ntawm 41% manganese raws li dej tov ib evkawj tuaj yeem ua tiav 100% cov nyhuv 30 hnub tom qab thov.
4. Cov av uas tsis muaj cultivated thiab embankments: kev daws teeb meem rau tshwj xeeb scenarios
Cov av uas tsis yog cog qoob loo: Siv 80-100 milliliters ntawm 20% emulsion thiab 100-150 milliliters ntawm 41% manganese dej tov ib evkawj tuaj yeem tiv thaiv thiab tswj cov nroj tsuag xws li hluav taws kub nyhiab nyom thiab raspberries.
Rice field embankment: Rau hollow lotus noob zaub, ib koob tshuaj los yog tov siv schemes siv tau. Piv txwv li, siv 50 milliliters ntawm 20% emulsion ib evkawj los yog 200 milliliters ntawm 20 milliliters emulsion ntxiv rau 41% manganese raws li dej tov tuaj yeem ua tiav 100% tswj cov nyhuv 15 hnub tom qab thov.
Weed control range: tag nrho cov kev pab cuam los ntawm cov nroj tsuag mus rau malignant weeds
1. Txhua xyoo broadleaf nroj
Nws muaj txiaj ntsig zoo rau kev tswj hwm cov nroj tsuag txhua xyoo xws li swine blight, foxtail nyom, nyuj foxtail nyom, tus tswv yug yaj lub hnab, thiab Artemisia annua. Piv txwv li, thaum tiv thaiv thiab tswj npua plague, siv 50 milliliters ntawm 20% emulsion ib evkawj tuaj yeem ua rau cov nroj tsuag tuag ntau dua 90% 7 hnub tom qab thov.

4. Nuv ntses kev nyab xeeb ceeb toom
Chlorofluoropyridineacetic acid yog cov tshuaj tua kab mob lom heev rau cov nyom carp, silver carp, thiab crucian carp. Qhov kev sim tau pom tias 96 teev LC50 qhov tseem ceeb yog 0.4764, 0.3962, thiab 0.6918 mg / L, raws li. Thaum siv cov tshuaj tua kab, nws yuav tsum nyob deb ntawm dej kom tsis txhob muaj cov kua dej ntws mus rau hauv lub pas dej ntses.
I. Core Raw Materials thiab Pretreatment
Cov ntaub ntawv tseem ceeb rau cov txheej txheem hluavtaws no yog 4-amino-3,5-dichloro-2-(methanesulfonyl)-6-fluoropyridine thiab ethyl glycolate, ntxiv los ntawm cov neeg ua haujlwm pabcuam suav nrog sodium hydroxide, sulfuric acid thiab theem hloov catalysts.
Raw khoom pretreatment yog ib qho tseem ceeb los lav cov tshuaj tiv thaiv efficiency. Qhov tseem ceeb pyridine intermediate yuav tsum tau dehydrated nyob rau hauv qhuav tej yam kev mob kom tsis txhob cuam tshuam cov dej ntawm nucleophilic hloov cov tshuaj tiv thaiv.
Lub caij no, homogeneous organic tov ntawm ethyl glycolate yog npaj. Quaternary ammonium theem hloov catalysts raug tshuaj xyuas los pab txhawb kev hloov pauv huab cua ntawm cov organic thiab aqueous theem, txo los ntawm - cov khoom tsim thiab nteg lub hauv paus rau cov tshuaj tiv thaiv condensation tom ntej.
II. Condensation thiab Esterification Reaction
Cov tshuaj tiv thaiv condensation ua haujlwm raws li cov txheej txheem hluavtaws hluavtaws thiab belongs rau nucleophilic hloov pauv. Nyob rau hauv lub reactor nruab nrog kub tswj thiab nplawm li, ntxiv cov pretreated pyridine intermediate, ethyl glycolate, ua ke nrog theem hloov catalyst thiab acid-binding agent.
Khaws cov cua sov tas li ntawm kwv yees li 70℃rau lub sijhawm ua haujlwm tsis tu ncua ntawm 2 teev. Thaum lub sij hawm cov tshuaj tiv thaiv, pawg nucleophilic ntawm ethyl glycolate hloov cov pab pawg methanesulfonyl ntawm lub nplhaib pyridine los tsim cov ethyl 2-[(4-amino-3,5-dichloro-6-fluoropyridin-2-yl)oxy]acetate.
Thaum cov tshuaj tiv thaiv tiav, ceev ceev lub kaw lus. Kev ntxuav dej yog siv los tshem tawm cov dej-soluble impurities; cov organic txheej yog sib cais thiab lub cev qhuav dej kom tau siab -purity ester intermediate, nrog rau cov khoom yield ntawm cov kauj ruam no mus txog 85%.
III. Hydrolysis thiab Acidification Reaction
Cov ester nruab nrab yog hloov mus rau hauv cov khoom ntsev ntawm alkaline hydrolysis, ua raws li acidification kom tau txais cov khoom kawg. Dissolve lub qhuav ester intermediate nyob rau hauv ethanol hnyav, ntxiv aqueous sodium hydroxide tov, kub mus txog 95℃thiab tuav rau ib nrab ib teev kom tiav ester bond hydrolysis, generating sodium ff4014.
Tom qab ntawd, txias cov tshuaj tiv thaiv kua thiab maj mam ntxiv dilute sulfuric acid dropwise los kho lub cev pH mus rau 1-2. Nyob rau hauv acidic tej yam kev mob, dawb ff4014 khoom precipitates los ntawm sodium ntsev. Cov acidification tus nqi thiab pH tus nqi yuav tsum nruj me ntsis tswj nyob rau hauv lub theem no los tiv thaiv cov khoom decomposition los ntawm ntau acidification thiab xyuas kom meej purity ntawm cov khoom tiav.
IV. Khoom Purification thiab Refining
Lub crude khoom precipitated tom qab acidification muaj kab impurities thiab yuav tsum tau ntxiv refining thiab purification. Sau cov khoom precipitate los ntawm kev pom, rov qab ntxuav nrog dej deionized kom tshem tawm cov ntsev seem thiab cov kuab tshuaj, thiab tom qab ntawd tshem tawm cov dej thiab cov kuab tshuaj organic los ntawm lub tshuab nqus tsev kom qhuav.
Recrystallization tuaj yeem ua tiav thaum kawg txhawm rau txhim kho cov qauv siv lead ua ntawm cov khoom, yielding technical ff4014 nrog tsim nyog purity thiab ruaj khov zog. Tag nrho cov txheej txheem hluavtaws nta cov tshuaj tiv thaiv me me thiab cov txheej txheem nruj, haum rau kev lag luam loj. Cov khoom muaj kev ua haujlwm siab thiab tsis muaj impurity cov ntsiab lus, ua raws li cov qauv zoo rau kev tsim tshuaj tua kab.
I. Physicochemical Properties
Technical ff4014 yog ib qho dawb rau tawm -dawb crystalline khoom nrog lub melting point ntawm kwv yees li 232-233℃. Nws muaj cov dej solubility tsawg ntawm qhov kub thiab txias, yooj yim yaj hauv cov kuab tshuaj organic xws li cawv thiab ketones, thiab yog soluble hauv alkanes. Nws muaj cov tshuaj lom neeg ruaj khov zoo thiab tiv thaiv kev puas tsuaj nyob rau hauv ib txwm cia tej yam kev mob ntawm chav tsev kub. Nws cov ester txuas yog raug rau hydrolysis nyob rau hauv muaj zog alkaline tej yam kev mob, thaum nws tseem nyob ruaj khov nyob rau hauv acidic ib puag ncig. Cov cua sov ntev ntawm qhov kub siab yuav ua rau maj mam degradation.
II. Cov yam ntxwv ua haujlwm lom neeg
Nws yog ib qho systemic translocatable pyridinoxyacetic acid herbicide. Nws hom kev ua haujlwm zoo li auxins, cuam tshuam kev faib tawm ntawm tes thiab kev loj hlob ntawm cov nroj tsuag broadleaf. Nws tsuas yog siv tau rau cov nroj tsuag dav dav thiab ua kom pom kev nyab xeeb rau cov qoob loo graminaceous. Tom qab nqus los ntawm cov nplooj ntoo, cov khoom xyaw nquag hloov mus rau cov ntsiab lus loj hlob, ua rau cov nroj tsuag malformation thiab wilting.
III. Environmental Properties
Nws yog yooj yim degraded los ntawm microorganisms nyob rau hauv cov av, featuring ib tug nruab nrab residual kev ua si lub sij hawm thiab tsawg residue txaus ntshai. Nws muaj toxicity tsawg rau ntses thiab muv, tseem yuav tsum tsis txhob muab tso rau hauv dej arbitrarily. Kev lag luam formulations feem ntau yog tsim los ua emulsifiable concentrates (EC) thiab ncua kev kawm ntawv concentrates (SC), haum rau post- tshwm sim foliar spray daim ntawv thov. Nws qhov kev ua tau zoo zoo li poob qis hauv qis - qhov kub thiab txias.
