Phenyl dichlorophosphate(Tshuaj mis C6h5opocl2) yog ib qho tseem ceeb organic phosphorus compound. Nyob rau hauv chav tsev kub, nws yog ib qho tsis muaj xim daj ua kua daj ua kua nrog cov ntxhiab tsw. Nws yog feem ntau tsim los ntawm cov tshuaj tiv thaiv ntawm phenol nrog trichhlorophosphoo. Qhov thib ob siab reactive chlorine atoms hauv nws cov qauv molecular thiab cov tshuaj phosfen pexygen gasygen thiab lub cev qhuav qhawv dav hauv cov organic synthesis. Nws yog qhov tshwj xeeb tshaj yog qhov tseem ceeb hauv phosphorylation kev cuam tshuam ntawm nucleotides, amino acids, thiab dej cawv. Qhov no compound yuav yauv npau taws hydrolysis thaum sib cuag nrog dej, tso cov pa roj thiab hydrogen. Yog li ntawd, nws yuav tsum tau ua kom zoo thiab khaws cia kom zoo zoo rau hauv kev mob siab, thiab nruj me ntsis anti {{corrosion thiab cov chaw dim cov chaw yuav tsum tau muab. Nyob rau tib lub sijhawm, nws muaj muaj zog irritancy thiab corrosiveness rau daim tawv nqaij, ob lub qhov muag, thiab tuaj yeem ua rau muaj tshuaj hlawv hnyav. Cov cuab yeej tiv thaiv tus kheej yuav tsum hnav thaum lub sijhawm ua haujlwm. Ib qho ntxiv, Phenylorophosphaphaphat kuj tseem yog tus tseem ceeb ua ntej rau cov khoom siv tshuaj tua kab, cov nplaim taws thiab cov tshuaj intermediates. Nws tuav txoj haujlwm tsis zoo rau hauv kev lag luam thiab lub chaw ua haujlwm, tab sis nws cov kev phom sij siab thiab ib puag ncig ib puag ncig kev siv nruj heev thiab khib nyiab pov tseg.

Piv nrog lwm cov phosphoryl chloride tebchaw tebchaw, PDCP muaj ntau heev phosphorylation. Nws yog cov phosphoryl reagent ntau siv nyob rau hauv cov khoom siv hluav taws xob los npaj symmetric phosphrode phosphodies.
Raws li kev ua haujlwm zoo rau tus neeg sawv cev,nwsMuaj peev xwm ntxias tau cov tshuaj tiv thaiv hws ntawm carboxylic acid thiab sulfide nyob rau hauv muaj pyridine kom tau thioxylates nrog siab tawm los. Lwm cov chlorophosphathat, xws li (Pho) 2p (ETO) 2p (OTO) 2p (O)) 2p (O)
NwsKuj tseem siv tau rau - halogenation ntawm cov alkali (xws li}}}}} kev hloov pauv ntawm cov ketones undatural.
NwsKuj yog ib qho zoo DMOPS ua kom cov reagent hauv PFTIZER MOFFATT cov tshuaj tiv thaiv. Cov complexes tsim nrog DMOs tuaj yeem siv ua oxidants los ntxias cov kev hloov dua siab tshiab ntawm thawj cov dej cawv lossis cov ketones.
Lub reflux ntawmpHenyl DichlorophosphateThiab sodium iodide hauv acetoniturile tuaj yeem paub txog kev hloov dua siab tshiab ntawm Etaws mus rau Alkyl iodide.
PDCP tseem tuaj yeem siv ua tus neeg sawv cev ua haujlwm zoo rau kev tawg c- o b {{1} s! Ketals lossis thioacetals tuaj yeem hloov pauv mus rau hauv cov khoom siv ketones ntsig txog kev ua ntawm PDCP thiab sodium iodide.
NwsKuj tseem tuaj yeem tsim cov complexes nrog dimethylformamide (yog li ua kom pom tseeb ib qho -}}}}}}} eceerification ntawm carboxylic acid substrate. Hom no yog tsim nyog tshwj xeeb rau kev tshajtub ntawm polysubstitected malonic acids, thiab tuaj yeem ua kom muaj txiaj ntsig zoo txog kev sib tw ntawm D Greaterbox.

Kev npaj ntawmPhenyl dichlorophosphate:
1. Cov txheej txheem hluavtaws
Hauv 500ml peb lub caj dab caj dab, 3559 (2.3mol) ntawm phosphorus oxychloride ntxiv, rhuab hauv cov roj da dej, thiab cov kua kub nce mus rau 80-90 degree. Thaum lub sijhawm tus txheej txheem no, lub kaw lus emits HCL Dawb haus luam yeeb thiab tswj qhov kub thiab txias. Thaum tsis muaj haus luam yeeb dawb tau tawm, cov cuab yeej tau qhuav, uas yog, 7.5g (0.068 xaim catalyst yog ntxiv, thiab cov kua kub yog tswj hwm ntawm 80-90 degree. Phenol yuav tsum ua kom sov thiab yaj ua ntej. Tom qab 150g (1.56Mol) ntawm cov phenol yaj tau ntxiv rau hauv kev poob mus rau hauv peb caj dab hauv cov kua kub ntawm 80-90 degree. Txoj kev ua kom ceev yuav muaj kev sib dhos. Tail roj yuav tsum raug tso tawm thiab qhov kub yuav tsis siab dhau. Txwv tsis pub, sab muaj kev phiv yuav tshwm sim. Tom qab poob rau Phenol, khaws cov tshuaj tiv thaiv ntawm 80-92℃kom txog thaum tsis muaj haus luam yeeb dawb yog tawm los ntawm qhov kub ntawm tus Tsov tus tw, thiab tom qab ntsuas kub mus rau 92-120 degree. Cov tshuaj tiv thaiv kawg taw tes yog thaum muaj cov pa luam yeeb dawb los ntawm tus Tsov tus tw tawm; Cov cuab yeej tus Tsov tus tw yuav tsum tau qhia rau hauv dej ntws nqus dej nqus cov kab ke, thiab lub sijhawm tshuaj tiv thaiv yog li 4H.
2. Distillation thiab txiav cov txheej txheem
(1) Tshaj phosphorus oxychloride yog rhuab thiab evaporated nyob rau hauv ib txwm siab hauv atmospheric distillation. Thaum cov roj theem kub nce mus rau 120 degree, tsis muaj distillate yog evaporated thiab atmospheric distillation nres nres.
(2) Nqus distillation tej yam kev mob ntawm distillate ua ntej nqus tsev distillation: Roj degree, chav ua kua kub: 06-150 theem kub: 9464.3paxa. Cov khoom ntim tau muaj cov ntsiab lus siabnws, Qhov hnyav: 250G, cov ntsiab lus siab dua lossis sib npaug rau 96%, tawm tsam txog 73%.
