2. Kev siv sib xyaw.

Kev sib xyaw talon nrog lwm cov tshuaj tua kab tuaj yeem nthuav tawm cov spectrum ntawm cov tshuaj tua kab thiab txo cov nqi. Hauv cov teb nplej, 30 mus rau 40 ml ntawm 20 feem pua ​​​​Talon emulsifiable concentrate ntxiv rau 35 ml ntawm 72 feem pua ​​2, 4-dibutyl ester emulsifiable concentrate los yog 150 ml ntawm 20 feem pua ​​​​dimethyltetrachloride aqueous tov tuaj yeem tiv thaiv thiab tua cov nroj tsuag xws li Veronica, Euphorbia, tus tswv yug yaj lub hnab, tus tswv yug yaj lub hnab, tus tswv yug yaj lub hnab, schizonepeta, chenopodium quinquefolium, endive, convolvulus, Ribes, Xanthium sibiricum, Abutilon theophrasti, thiab lwm yam; Siv 50 mus rau 66.7ml ntawm 20 feem pua ​​​​Tetron emulsifiable concentrate thiab 50 mus rau 67ml ntawm 6.9 feem pua ​​Puma dej emulsion ib mu tuaj yeem tiv thaiv thiab tua cov nroj tsuag xws li qus oats, damselflies, nyom nyom, clubbed nyom, barnyard nyom, crabgrass, thiab millet. .

Lub chaw kuaj kev npaj ntawm qhov sib xyaw no yuav raug qhia, suav nrog kev npaj cov khoom siv raw, kev tswj xyuas cov tshuaj tiv thaiv, kev npaj nruab nrab thiab kev ua kom huv ntawm cov khoom.

Cov kauj ruam ntawm kev sim ua haujlwm yog raws li hauv qab no:

Kauj Ruam 1: Kev npaj raw khoom:

Cov khoom siv hluavtaws ntawmFluroxypyrsuav nrog 2-chloro-6-fluoropyridine (2-chloro-6-fluoropyridine), 3,5-dichloro-4-aminopyridine-2-carboxylic acid ( 3, 5-dichloro-4-aminopyridine-2 -carboxylic acid) thiab sodium nitrite (sodium nitrite), thiab lwm yam. Cov khoom siv raw no yuav tsum tau ua raws li cov txheej txheem xws li kev kho kom zoo, ua kom huv thiab hnyav kom ntseeg tau. lawv purity, zoo thiab raug ntawm kom muaj nuj nqis.

Kauj Ruam 2: Kev tswj cov tshuaj tiv thaiv:

Tom qab cov khoom siv raw tau npaj, nws yuav tsum tau txiav txim siab txog cov tshuaj tiv thaiv, suav nrog qhov kub thiab txias, lub sijhawm tshuaj tiv thaiv, pH tus nqi, thiab cov tshuaj reactant ratio, raws li qhov sib piv molar nyob rau hauv qhov sib npaug ntawm cov tshuaj tiv thaiv thiab cov khoom ntawm cov tshuaj reactant. Thaum lub sij hawm synthesis ntawm cov khoom, nws yog feem ntau yuav tsum tau ntxiv sodium hydroxide (sodium hydroxide) thiab nyiaj chloride (silver chloride), thiab lwm yam. Cov khoom pab no pab txhawb kev nce qib ntawm cov tshuaj tiv thaiv thiab kev ua kom huv ntawm cov khoom.

Kauj Ruam 3: Kev npaj cov khoom nruab nrab:

Lub synthesis ntawm cov khoom muaj ntau yam intermediates, thiab nws cov txheej txheem kev npaj yuav tsum tau nruj me ntsis tswj ntawm cov tshuaj tiv thaiv tej yam kev mob thiab qhov zoo ntawm intermediates los xyuas kom meej qhov zoo ntawm cov kauj ruam tom ntej. Piv txwv li, nyob rau hauv thawj kauj ruam, nws yog tsim nyog los sib tov 2-chloro-6-fluoropyridine thiab 3,5-dichloro-4-aminopyridine-2-carboxylic acid nyob rau hauv ib tug tej yam. kev faib ua feem, thiab ntxiv sodium nitrite los tsim 4-chloro -6-fluoro-2-azapyridine. Qhov no yog ib qho tseem ceeb nruab nrab ntawm cov khoom thiab yuav tsum muaj kev hloov pauv ntxiv.

Kauj Ruam 4: Cov khoom purification:

Cov khoom ntawmFluroxypyryuav tsum tau purified thiab sib cais kom tau lub hom phiaj khoom nrog siab purity. Kem chromatography, kuab tshuaj extraction, thiab crystallization feem ntau yog siv rau purification, thiab qhov zoo thiab purity ntawm cov khoom yuav tsum tau kuaj, xws li chromatography, huab hwm coj spectrometry, thiab nuclear magnetic resonance.

Feem ntau hais lus, nws yog ib qho nyuaj organic compound, thiab nws cov kev sim synthesis yuav tsum tau paub txog qee yam tshuaj hauv paus thiab kev sim kev txawj ntse, thiab tib lub sijhawm, kev saib xyuas yuav tsum tau them rau kev tswj cov tshuaj tiv thaiv thiab kev ua kom huv ntawm cov khoom. Yog tias qhov kev lag luam loj loj yuav tsum tau ua, cov khoom xws li kev lag luam kev lag luam thiab kev nyab xeeb kuj yuav tsum tau xav txog.

1. Nws tuaj yeem tiv thaiv thiab tua tau ntau yam kab tsuag, xws li Sarcophagium japonicum, Polygonum hydropiper, Portulaca oleracea, Solanum nigrum, Fanzhou, Vetiver, Convolvulus officinalis, Polygonum sinense, Polygonum salicifolium, Amaranthus retroholracisup, Commelina colleans Vicia vulgaris, Artemisia scoparia thiab Convolvulus, uas tsis zoo rau gramineae thiab sedge weeds.

2. Nws muaj kev nyab xeeb rau cov qoob loo. Nyob rau hauv cov qoob loo resistant, nws tuaj yeem ua ke nrog conjugates kom poob toxicity.

3. Nws yog ib qho yooj yim rau degrade nyob rau hauv cov av, nrog ib tug luv luv ib nrab-lub neej, thiab yuav tsis ua mob rau cov qoob loo tom ntej.
