Benzene; Benzol Phenyl hydride Cyclohexatriene Coalnaphtha; Phene (CAS # 71-43-2)
71-43-2 : kuvTaw Qhia: Nkag siab nws qhov tseem ceeb
Hauv thaj chaw ntawm cov tebchaw, "71-43-2" yog hais txog ib yam khoom hu ua benzene. Benzene yog ib qho uas muaj ntxhiab hydrocarbon uas yog lub hauv paus ntawm cov organic chemistry txij li thaum nws nrhiav tau nyob rau hauv thaum ntxov 19th caug xyoo. Nws cov mis molecular C6H6 qhia tau hais tias nws yog tsim los ntawm rau carbon atoms thiab rau hydrogen atoms teem nyob rau hauv ib tug planar nplhaib qauv nrog resonance stability.
Qhov laj thawj yog vim li cas benzene tseem ceeb tsis yog vim nws cov tshuaj lom neeg tshwj xeeb, tab sis kuj vim nws tau siv dav hauv ntau yam lag luam. Nws yog cov khoom tseem ceeb rau kev sib txuas ntau yam tshuaj, suav nrog plastics, resins, hluavtaws fibers, thiab dyes. Cov compound no kuj yog ib qho tseem ceeb rau cov khoom lag luam tseem ceeb xws li ethylbenzene, isopropylbenzene, thiab cyclohexane, uas ua lub luag haujlwm tseem ceeb hauv kev tsim cov polystyrene thiab lwm yam ntaub ntawv.
Txawm li cas los xij, qhov tseem ceeb ntawm benzene tsis txwv rau kev tsim khoom lag luam, tab sis kuj ua rau muaj kev txhawj xeeb txog nws cov tshuaj lom thiab muaj peev xwm ua rau muaj kev phom sij rau kev noj qab haus huv. Kev raug benzene ntev ntev tuaj yeem ua rau muaj teeb meem kev noj qab haus huv, suav nrog leukemia thiab lwm yam kab mob ntshav. Yog li ntawd, cov koom haum tswj hwm thoob plaws ntiaj teb tau tsim cov lus qhia los txwv tsis pub muaj kev cuam tshuam thiab ua kom muaj kev nyab xeeb kev coj ua hauv kev lag luam ib puag ncig.
Feem ntau hais lus, txheeb xyuas benzene los ntawmCAS 71-43-2 Nrhighlights nws dual xwm raws li ib tug tseem ceeb muaj tshuaj lom neeg thiab ib tug txaus ntshai tshuaj. Kev nkag siab txog cov khoom, kev siv, thiab kev pheej hmoo yog qhov tseem ceeb rau cov kws kho mob, cov chaw tsim khoom, thiab cov koom haum tswj hwm. Raws li peb txuas ntxiv mus kawm qhov nyuaj ntawm cov tebchaw, benzene tseem yog lub ntsiab lus tseem ceeb hauv kev tshawb fawb kev kawm thiab kev ua lag luam.
