Ikhabhoni
Isingeniso somkhiqizo
MF: C
MW: 12.011
I-CAS: 7440-44-0
I-EINECS: 231-153-3
Ikhabhoni iyingxenye ye-nonmetallic eqenjini le-IVA lethebula le-bai lenkathi yesibili.Igama lesiLatini lisho iCarbonium, okusho ukuthi “amalahle, amalahle”.Uhlamvu lwesiShayina oluthi "carbon" lwakhiwe "carbon" yamalahle kanye negama letshe, elisuka kumsindo othi "carbon".Ikhabhoni iyinto evamile kakhulu, etholakala kabanzi ngezindlela eziningi kugesi ye-Chemicalbook enkulu kanye noqweqwe lomhlaba.Ikhabhoni kade yaziwa futhi isetshenziswa, futhi uchungechunge lwezinhlanganisela zekhabhoni, izinto eziphilayo, zibalulekile empilweni.Ikhabhoni iyingxenye yensimbi yengulube, insimbi ekhandiwe nensimbi.Ikhabhoni iyi-molecule ebaluleke kakhulu ngokwebhayoloji nakwezentengiso ezibophezela ngokwamakhemikhali ukuze yakhe inqwaba yezinhlanganisela.Ama-molecule amaningi ezinto eziphilayo aqukethe ikhabhoni.
Izakhiwo zamakhemikhali
Amakristalu angama-porous amnyama noma ama-granular.Iphoyinti elibilayo elingu-4827℃, 3652℃ sublimation, ukuminyana kwesihlobo mayelana nokungu-1.8-2.1, ukuminyana kwesihlobo sokusebenza cishe ngu-0.08-0.45.
sebenzisa
(1) ukuhlanzwa kwegesi, njengokusebenzisa ikhabhoni ecushiwe ukuze kubuyiselwe isincibilikisi emoyeni esiqukethe umhwamuko;Ukusebenzisa indlela yokuhlunga ikhabhoni ecushiwe ukuze uqede iphunga lomoya;Noma isetshenziswa kumamaski egesi nasezintweni zokuphefumula zasembonini ukuvikela ezintweni ezinobuthi.
(2)Ukuhlukaniswa kwegesi, okufana nokutholwa kwe-benzene kugesi yedolobha, uphethiloli, i-propane kanye nokutholwa kwe-butane kusuka kugesi yemvelo, esetshenziselwa ukwelapha igesi engcolile ku-fischer-tropsch synthesis, ukuze kutholwe ama-hydrocarbon.(3) i-adsorption yesigaba samanzi njengasembonini kashukela ene-Chemicalbook activated carbon adsorption method ukuze ihlukanise uketshezi lukashukela, embonini yamakhemikhali enekhabhoni ecushiwe ukuze ikhiphe umbala izinto eziphilayo, ngokuhlanzwa kwekhabhoni okucushiwe kokungcola okuphilayo endaweni yokugeza ye-electroplating, ukuqinisekisa ukuthi ikhwalithi ye-electroplating surface noma esetshenziselwa ukuchithwa kwamanzi angcolile.
(4).Ama-catalysts noma abathwali be-catalyst njengama-catalysts asetshenziselwa i-industrial gas desulfurization nokukhiqizwa kwe-phosgene, njll ezinye izici ze-steam nezinye.
