I-Benzol;i-Benzol Phenyl hydride Cyclohexatriene Coalnaphtha;Phene (CAS#71-43-2)

71-43-2Isingeniso: Ukuqonda ukubaluleka kwayo

Emkhakheni wezinhlanganisela, “71-43-2″ isho into ethile ebizwa nge-benzene. I-Benzene iyi-hydrocarbon enephunga elimnandi ebilokhu iyisisekelo samakhemikhali ezinto eziphilayo kusukela yatholakala ekuqaleni kwekhulu le-19. Ifomula yayo yamangqamuzana i-C6H6 ibonisa ukuthi yakhiwe ama-athomu ekhabhoni ayisithupha nama-athomu e-hydrogen ayisithupha ahlelwe ngesakhiwo sendandatho eplaniwe enokuqina kokuzwakala kwe-resonance.

Isizathu sokuthi kungani i-benzene ibalulekile akukona nje kuphela ngenxa yezakhiwo zayo zamakhemikhali eziyingqayizivele, kodwa futhi ngoba isetshenziswa kakhulu ezimbonini ezihlukahlukene. Iyingxenye eyinhloko yokwenziwa kwamakhemikhali amaningi, okuhlanganisa amapulasitiki, ama-resin, imicu yokwenziwa, nodayi. Le nhlanganisela iphinde ibe yisandulela samakhemikhali ezimboni abalulekile njenge-ethylbenzene, isopropylbenzene, ne-cyclohexane, adlala indima ebalulekile ekukhiqizeni i-polystyrene nezinye izinto.

Nokho, ukubaluleka kwe-benzene akugcini nje embonini yokukhiqiza, kodwa futhi kuphakamisa ukukhathazeka ngobuthi bayo kanye nobungozi bezempilo obungaba khona. Ukuchayeka isikhathi eside ku-benzene kungadala izinkinga ezinkulu zempilo, okuhlanganisa i-leukemia nezinye izifo zegazi. Ngakho-ke, ama-ejensi alawulayo emhlabeni wonke athuthukise imihlahlandlela yokukhawulela ukuchayeka nokuqinisekisa izinqubo zokuphatha eziphephile ezindaweni zezimboni.

Ngokuvamile, ukuhlonza benzene ngokusebenzisaI-CAS 71-43-2igqamisa ubunjalo bayo obumbaxambili njengekhemikhali yezimboni ebalulekile kanye nento eyingozi. Ukuqonda izakhiwo, izinhlelo zokusebenza, kanye nezingozi kubalulekile kosokhemisi, abakhiqizi, nama-ejensi alawulayo. Njengoba siqhubeka nokufunda ubunkimbinkimbi bezinhlanganisela, i-benzene isalokhu iyisihloko esibalulekile ocwaningweni lwezemfundo kanye nokusebenza kwezimboni.
