1 3-dibromo-5-fluorobenzene (CAS # 1435-51-4) Kev taw qhia
1,3-Dibromo-5-fluorobenzene yog cov organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, lub hom phiaj, kev tsim khoom, thiab cov ntaub ntawv kev nyab xeeb:
xwm:
1,3-Dibromo-5-fluorobenzene yog cov kua tsis muaj xim uas muaj ntxhiab tsw. Nws yog insoluble nyob rau hauv dej nyob rau hauv chav tsev kub, tab sis soluble nyob rau hauv cov organic solvents xws li ethanol, carbon disulfide, thiab lwm yam. Nws yog ib qho yooj yim mus decomposition ntawm kub kub thiab tso pa phem gases.
Lub hom phiaj:
1,3-Dibromo-5-fluorobenzene feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis rau cov synthesis ntawm lwm cov tebchaw. Nws kuj yog siv los ua cov catalyst thiab hnyav rau cov organic synthesis cov tshuaj tiv thaiv.
Txoj kev tsim khoom:
Kev npaj ntawm 1,3-dibromo-5-fluorobenzene tuaj yeem ua tiav los ntawm reacting 1,3-dibromobenzene nrog fluoride nyob rau hauv cov kev mob tshwm sim. Cov tshuaj tiv thaiv no feem ntau yuav tsum tau ua raws li kev tiv thaiv roj inert kom tsis txhob muaj cov khoom phom sij tsim nyob rau hauv acidic tej yam kev mob.
Cov ntaub ntawv kev ruaj ntseg:
1,3-Dibromo-5-fluorobenzene yog ib qho organic compound thiab yuav tsum tau saib xyuas thiab khaws cia nrog kev saib xyuas. Nws muaj teebmeem rau ntawm daim tawv nqaij, qhov muag, thiab ua pa, thiab tej zaum yuav ua rau muaj kev phom sij rau kev noj qab haus huv. Thaum siv, cov cuab yeej tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab qhov ncauj qhov ntswg yuav tsum hnav. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov thaum tuav thiab khaws cia, thiab xyuas kom muaj chaw ua haujlwm zoo. Nyob rau hauv tsis muaj qhov xwm txheej yuav tsum koj tuaj rau hauv kev sib cuag ncaj qha nrog qhov sib xyaw no thiab ua rau nws ceev faj.
Thaum siv, tuav, thiab khaws cov tshuaj lom neeg, thov nco ntsoov ua raws li cov txheej txheem kev nyab xeeb ntawm kev ua haujlwm thiab ua raws li cov kev cai hauv zos.
