3 4-Dibromobenzoic acid (CAS # 619-03-4)
Taw qhia
3,4-Dibromobenzoic acid yog cov organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
3,4-Dibromobenzoic acid yog cov xim tsis muaj kob uas muaj ntxhiab tsw tshwj xeeb. Nws ruaj khov rau lub teeb thiab huab cua, tab sis tuaj yeem decompose ntawm qhov kub thiab txias.
Siv:
3,4-Dibromobenzoic acid tuaj yeem siv rau hauv cov tshuaj sib txawv thiab cov tshuaj reagents hauv cov organic synthesis. Nws kuj tseem siv tau los ua ib qho ntawm cov khoom siv rau cov organic teeb-emitting diodes (OLEDs).
Txoj kev:
Kev npaj ntawm 3,4-dibromobenzoic acid tuaj yeem tau txais los ntawm bromination ntawm kev daws ntawm bromobenzoic acid. Benzoic acid yog thawj zaug yaj hauv cov kuab tshuaj tsim nyog thiab tom qab ntawd bromine ntxiv maj mam. Tom qab cov tshuaj tiv thaiv tiav, cov khoom tau txais los ntawm kev pom thiab crystallization.
Cov ntaub ntawv kev nyab xeeb: Nws belongs rau qeb ntawm cov organic halides thiab muaj peev xwm ua rau muaj kev phom sij rau tib neeg thiab ib puag ncig. Tsis txhob kov ncaj qha rau ntawm daim tawv nqaij thiab ob lub qhov muag, thiab xyuas kom meej tias koj ua haujlwm nyob rau hauv qhov chaw ua haujlwm zoo. Kev tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav kev nyab xeeb, thiab lub tsho tiv no yuav tsum tau ua thaum tuav cov khoom sib xyaw no. Cov khib nyiab yuav tsum tau muab pov tseg kom raug kom ua raws li cov cai hauv cheeb tsam ib puag ncig.
