Benzene;Benzol Phenyl hydride Cyclohexatriene Coalnaphtha;Phene (CAS#71-43-2)
71-43-2Mawu Oyamba: Kumvetsa tanthauzo lake
Pankhani ya mankhwala, "71-43-2" amatanthauza chinthu china chotchedwa benzene. Benzene ndi hydrocarbon yonunkhira yomwe yakhala mwala wapangodya wa organic chemistry kuyambira pomwe idapezeka koyambirira kwa zaka za zana la 19. Mapangidwe ake a molekyulu C6H6 akuwonetsa kuti amapangidwa ndi maatomu asanu ndi limodzi a kaboni ndi maatomu asanu ndi limodzi a haidrojeni opangidwa mu dongosolo la mphete lokhala ndi kukhazikika kwa resonance.
Chifukwa chomwe benzene ndi yofunika osati chifukwa cha mankhwala ake apadera, komanso chifukwa amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Ndilo gawo lalikulu popanga zinthu zambiri zamakemikolo, kuphatikiza mapulasitiki, utomoni, ulusi wopangira, ndi utoto. Pagululi ndi kalambulabwalo wamankhwala ofunikira amakampani monga ethylbenzene, isopropylbenzene, ndi cyclohexane, omwe amagwira ntchito yofunika kwambiri popanga polystyrene ndi zida zina.
Komabe, kufunikira kwa benzene sikungokhudza makampani opanga zinthu, komanso kumadzetsa nkhawa za kawopsedwe kake komanso kuopsa kwa thanzi. Kukumana ndi benzene kwa nthawi yayitali kungayambitse matenda aakulu, kuphatikizapo khansa ya m'magazi ndi matenda ena a magazi. Chifukwa chake, mabungwe owongolera padziko lonse lapansi apanga malangizo oletsa kuwonekera ndikuwonetsetsa kuti njira zogwirira ntchito zotetezeka m'mafakitale.
Nthawi zambiri, kuzindikira benzene kudzeraChithunzi cha CAS 71-43-2ikuwonetsa zapawiri zake ngati mankhwala ofunikira amakampani komanso chinthu chowopsa. Kumvetsetsa katundu, ntchito, ndi zoopsa ndizofunikira kwambiri kwa akatswiri opanga mankhwala, opanga, ndi mabungwe olamulira. Pamene tikupitiriza kuphunzira zovuta za mankhwala, benzene ikadali mutu wofunikira pa kafukufuku wamaphunziro ndi machitidwe a mafakitale.
