Zoo siv
Canonical luag nyav:C1 = CC = C (C = C1) NC (= O) N
Siv:Phenyluras feem ntau siv av-thov cov tshuaj ntsuab rau kev tswj ntawm cov nyom thiab me-seeded broadleafeaf weds. Cov ecyl urerea siv rau hauv synthic synthesis. Nws ua raws li kev ua haujlwm zoo rau palladium-cataly-catalyzed heck thiab suzuki kev cuam tshuam ntawm aryl bromides thiab iodides
Cov lus qhia ntxaws ntxaws
1-phenyea, tseem hu ua PhenylcarbonyLurea lossis N-Phenylrea, yog cov organic sib xyaw nrog cov tshuaj c7h8n2o. Nws yog lub ntsej muag dawb crystalline uas yog sparingly soluble hauv dej tab sis soluble hauv cov kuab tshuaj organic.
Phenysa feem ntau siv nyob rau hauv kev ua liaj ua teb raws li cov nroj tsuag kev tswj hwm kev nyab xeeb. Nws ua raws li CyTokinin kev thaiv kev thaiv, lub ntsiab lus nws inhibits qhov kev txiav txim ntawm CyTokinins, uas yog cov nroj tsuag cov tshuaj hormones rau kev sib cais ntawm tes thiab kev loj hlob ntawm cell thiab kev loj hlob. Los ntawm inhibiting cytokinins, Phenyylurea tuaj yeem tswj txoj kev loj hlob thiab kev tsim kho cov kev cuam tshuam xws li kev nce qib ntxiv, thiab tswj cov hauv kev loj hlob tuaj yeem loj hlob.
Vim tias nws cov nroj tsuag kev loj hlob-tswj cov khoom, phenyesa pom cov ntawv thov hauv ntau txoj kev ua liaj ua teb. Nws yog siv los tswj cov zaub ntsuab dhau los hauv horticulture thiab tsev cog khoom qoob loo, txhawb nqa cov nroj tsuag ntxiv thiab tswj cov cog qoob loo ntau dua. Phenylurea kuj tseem tuaj yeem siv tau kom ncua cov senescence (laus) ntawm cov txiv hmab txiv ntoo thiab zaub, nthuav lawv lub txee lub neej.
Ntxiv rau nws siv kev ua liaj ua teb, phenylurea kuj tau pom muaj peev xwm ua lwm thaj chaw. Nws tau kawm rau nws cov antifungal thiab antimicrobial cov yam ntxwv, xav kom nws ua tau siv ua fungicide lossis txuag tshuaj tiv thaiv. Tsis tas li ntawd, Phenyylenea derivatives tau raug tshuaj xyuas rau lawv cov ntawv thov tshuaj, xws li tshuaj tiv thaiv kab mob thiab cov tshuaj tiv thaiv kab mob antensor.
Nws yog ib qho tseem ceeb kom nco ntsoov tias kev siv phenylrea lossis nws cov kev ua tiav hauv kev ua liaj ua teb thiab siv tau kev nyab xeeb thiab siv tau cov kev pheej hmoo ntawm ib puag ncig thiab kev tsis txaus siab.
Daim ntawv thov
1-Phenyylurea, tseem hu ua N-Phenylrea, muaj ntau yam kev thov hauv ntau daim teb. Ntawm no yog ob peb cov ntawv thov tseem ceeb:
Kev Tsim Kev Cog Kev Cog Khoom:1-phenyesa tau siv dav raws li cov nroj tsuag kev loj hlob regulator thiab tau qhia los txhawb lub hauv paus kev loj hlob thiab inhibit tua kev loj hlob hauv cov nroj tsuag. Nws tuaj yeem raug siv los tswj cov nroj tsuag qhov siab thiab txhawb nqa tom qab ceg hauv cov nroj tsuag ornamental.
Cov neeg tua tsiaj txhu synergist:1-phenyesa feem ntau siv los ua tus thawj coj hauv cov tshuaj tua kab. Nws txhim kho cov haujlwm thiab kev ua tau zoo ntawm cov tshuaj ntsuab los ntawm kev txhim kho lawv cov kev nqus, kev siv hluav taws xob, thiab ua tau zoo thiab ua tau zoo rau cov nroj.
Kws Tshuaj Nruab Nrab:1-phenyesa tau siv los ua cov compound intermediate nyob rau hauv cov synthesis ntawm ntau cov tshuaj, xws li tshuaj tua kab mob thiab tshuaj tiv thaiv tshuaj. Nws pabcuam ua lub tsev thaiv cov khoom ntim hauv kev tsim cov khoom sib txuas ntxiv.
Analytical reagent:1-phenyea tau siv los ua kev ntsuas tshuaj tiv thaiv tshuaj lom neeg tshuaj xyuas thiab tshawb fawb lub chaw soj ntsuam chaw soj ntsuam. Nws tuaj yeem ua haujlwm rau ntau lub hom phiaj, suav nrog kev txiav txim siab ntawm cov kab laij teb hlau, kev tsom xam ntawm cov organic sib txuas, thiab ua cov qauv siv.
Polymerization catalyst:1-phenyesa tuaj yeem ua raws li catalyst nyob rau hauv qee cov tshuaj tiv thaiv polymerization. Nws pab hauv kev tsim cov polymers los ntawm kev pib lossis txhawb kev siv tshuaj lom neeg uas ua rau cov khoom siv polymeres nrog cov khoom xav tau.
Organic synthesis:1-phenyfurea yog dav siv nyob rau hauv cov articic synthesis ua ib tug reactant lossis reagent. Nws tuaj yeem koom nrog kev tawm tsam xws li hws, rov qab, thiab kev sib deev, ua rau kev tsim cov organic sib xyaw.
Nws yog ib qho tseem ceeb kom nco ntsoov tias thaum siv 1-phenylurea lossis ib qho kev tshuaj lom neeg, nws yog cov cai tswj hwm kom ntseeg tau tias kev nyab xeeb thiab ib puag ncig kev nyab xeeb.
