Hom ntawm 2-Bromophenol
Monobromophenols
Monobromophenols muaj nyob rau hauv tag nrho ntawm peb isomers, ib tug ntawm uas yog hu ua 2-bromophenol. Qhov no yog vim hais tias ib leeg bromine atom tsuas yog nyob ib qho ntawm peb lub nplhaib txoj haujlwm ntawm phenol molecule. Pentabromophenol, ntawm qhov tod tes, tsuas muaj nyob hauv ib qho isomer vim qhov tseeb tias tag nrho tsib ntawm phenol nplhaib txoj haujlwm tau raug coj los ntawm bromine atoms. Txhawm rau ua ke ib qho monobromophenol, tsuas yog ib qho bromine molecule tau koom ua ke ntawm ib qho carbon ntawm benzene nplhaib ntawm phenol compound.

Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv thaum muaj xwm txheej ceev rau cov dej xau thiab cov ntaub ntawv tsim nyog.
Synthesis ntawm 2-bromophenol
2-bromophenol yog ib qho tseem ceeb ntawm cov khoom siv raw khoom thiab nruab nrab, feem ntau yog siv rau hauv kev sib txuas ntawm cov tshuaj, tshuaj tua kab thiab lwm yam tshuaj zoo, thiab tseem tuaj yeem siv rau hauv cov yas thiab roj hmab additives. Kev xaiv ntau yam ntawm 2-bromophenol yog qhov tseem ceeb hauv kev txo nqi ntawm cov khoom siv tshuaj hluavtaws thiab yog li txo cov nqi tshuaj.
2-bromophenol yog synthesized los ntawm ncaj qha bromination cov tshuaj tiv thaiv ntawm phenol ua raw khoom. Kev xaiv ntawm 2-bromophenol nyob rau hauv cov tshuaj tiv thaiv bromination ntawm phenol thiab bromine yog tsawg heev. Cov kev tshawb fawb tau pom tias kev ua haujlwm ntawm phenol, 2-bromophenol, 4-bromophenol, thiab 2,4-dibromophenol hauv cov tshuaj tiv thaiv bromine hloov maj mam txo qis. Nyob rau hauv cov tshuaj tiv thaiv ntawm phenol oxidative bromination rau synthesize 2-bromophenol, ib tug sodium bromide-hydrogen peroxide cov tshuaj tiv thaiv kab mob yog siv, thiab acetic acid yog siv raws li Solvent, triethylamine raws li cov tshuaj tiv thaiv additive, nyob rau hauv lub pom tej yam kev mob, kev hloov pauv ntawm phenol. oxidation bromination rau synthesize 2-bromophenol yog 55.2%, thiab cov selectivity yog 31.2%. Txoj Kev 2: Synthesis ntawm 2-bromophenol los ntawm indirect bromination cov tshuaj tiv thaiv ntawm phenol, siv 4-tert-butylphenol ua raw khoom rau bromination los tsim 2-bromo-4-tert-butylphenol nrog ib tug hloov pauv tus nqi ntawm 99.9% thiab tawm los ntawm 99.6%.
Kev cuam tshuam ntawm yam xws li tert-butyl txais, lub sij hawm tshuaj tiv thaiv, thiab catalyst ntawm cov synthesis ntawm 2-bromophenol los ntawm tert-butyl hloov cov tshuaj tiv thaiv ntawm 2-bromo-4-tert-butylphenol. Nrog AlCl_3 ua catalyst, phenol li tert-butyl txais thiab hnyav, thaum molar ratio ntawm 2-bromo-4-tert-butylphenol: aluminium chloride: phenol yog 1: 1: 3, tus nqi hloov pauv ntawm 2-bromo-4-tert-butylphenol rau 2-bromophenol yog 69.2% tom qab 5 h ntawm cov tshuaj tiv thaiv ntawm 40 degree . Thaum toluene tau siv los ua tert-butyl txais, kab dej muaj qhov cuam tshuam tseem ceeb ntawm cov tshuaj tiv thaiv catalytic.
Nyob rau hauv cov tshuaj tiv thaiv hlab ntsha nrog ib tug distillation ntaus ntawv, ntxiv 5.6mol ntawm 1-amino-3-bromo-propanol, 6.1-6.3mol ntawm 2-bromophenol tov, 800ml ntawm poov tshuaj bromide tov, 2.56mol ntawm txhuas oxide, 700ml ntawm hexane, thiab 300ml ntawm sodium sulfite tov, tsa cov tshuaj kub rau 70-75 degree, react rau 3-5h, txo cov tshuaj kub rau 50-55 degree , tswj lub stirring ceev mus rau 110-150rpm, reflux rau 90-110min, txo cov tshuaj kub rau 10-13 degree, sawv ntsug rau 2-5h, cais cov tshuaj, tshem tawm cov roj txheej, ntxuav nrog ntsev, ntxuav nrog acetonitrile, ntxuav nrog isopropanol, distilled nyob rau hauv lub siab txo, sau cov feem ntawm 80--85 degree, recrystallize nyob rau hauv nitromethane, thiab tau crystalline epibromopropane.
(1) Ua ntej dehydrogenate m-fluorochlorobenzene nrog n-butyl lithium, tom qab ntawd hloov cov tshuaj tiv thaiv nrog triisopropyl borate, thiab tom qab ntawd yaug cov kua qaub hydrolysis kom tau txais 2-fluoro-6-chlorophenylboric acid; (2) Raws li kev ua ntawm tetrakis (triphenylphosphine) palladium thiab potassium carbonate, 2-fluoro-6-chlorophenylboric acid reacts nrog 2-bromophenol kom tau txais 2-fluoro-6- chloro{11}}'-hydroxy-1,1'-biphenyl; (3) 2-fluoro-6-chloro-2'-hydroxy-1,1'-biphenyl reacts nrog N-bromosuccinimide kom tau txais 2-fluoro{{26} }chloro-2'-hydroxy-5'-bromo-1,1'-biphenyl; (4) 2-fluoro-6-chloro-2'-hydroxy-5'-bromo-1,1'-biphenyl tau txais cov tshuaj tiv thaiv cyclization raws li kev ua ntawm potassium carbonate kom tau 1'-chloro-8-bromodibenzofuran.
