Njengoko iasithilini walungisa ukusuka methane

Iasithilini lulwelo ukubayinxalenye udidi alkynes. Ngamanye amazwi, le ezizizembiwa ethe nganye zinemoletyhule bond kathathu. Kule chemical iasithilini formula ngolu hlobo lulandelayo: C ₂ H _2. Ngokwayo, le nto irhasi enemibala emihle, nto leyo elula kakhulu emoyeni. Iasithilini lungafumaneka methane. Le nto ke lovukelo Uyadubula.

Zifunyanwa njani iincwadi iasithilini

Methane ekhaya ukufumana iasithilini kunzima kakhulu. Indlela elula ukuba Ukuqhela irhasi - la manzi idityaniswe kule calcium carbide. Abaninzi kuni mhlawumbi khumbula indlela ukugibisela izadunge kwezahlulo lwesiyobisi basabela njani kwenzeka. Kuye kwaqatshelwa ukuba hi ngokukhawuleza. Ke ukuba calcium khabhayithi, ngoko ke kancane sayeka, ekwenzeni imali eninzi njengogwebu. A ukusabela okufanayo angabhalwa ngolu hlobo:

CaC ₂ + 2H ₂ O = C ₂ H ₂ + Ca (OH) _2.

isetyenziswa ezininzi zobugcisa calcium khabhayithi, equlethe isixa esikhulu ukungcola. Ngenxa yoko, izinto reaction ngamanzi ukhupha livumba embi. Oku kuvela ukusekwa, kunye isixa minor yerhasi iasithilini umphunga oyityhefu. Kaninzi iba phosphine, emanzini, njalo-njalo. Le ndlela yeyona eqhelekileyo kakhulu, njengoko ukufumana iasithilini evela methane kunokwenzeka kuphela kunye nezixhobo ezizodwa.

Industry ukulungiselela

Ungayifumana njani le iasithilini ukusuka methane kwimeko yamashishini? Okwangoku wasebenzisa indlela enye kuphela - ng. Ngexesha ukulungiswa iasithilini lwenziwa decoupling -C-C. Oku kwenzeka phambi ehlanganisa kwakunye exposure sezingeni eliphezulu lobushushu. Kuba usebenzisa methane - igesi yendalo. Eli izinto engaxabisi kakhulu yaye zifumaneka lula ekrwada. Kungenxa yesi sizathu ukuba nokuqhekeka yindlela enengqondo zombini ngokwezoqoqosho enyanisweni.

eyonakele njani

Ukwenza uguqulo "methane - iasithilini" ngeendlela ezininzi. Kwimeko yokuqala, irhasi yendalo wacanda electrode pre-shushu. Iqondo lobushushu unako ukufikelela 1600 ° C. Emva ubushushu, ukupholisa rapid kwenzeka. Indlela yesibini isekelwe phezu ukusetyenziswa ubushushu leyo eyenziwe ukutshiswa kwenxenye iasithilini.

Reaction equation "methane - iasithilini" zibhalwe ngolu hlobo lulandelayo:

1. Xa I: 2Kr ₄ = C ₂ H ₂ + 3h _2.

1. Kwimeko II: 6SN ₄ + 4O ₂ = C ₂ H ₂ + 8H + 3Ngoko ₂ + CO ₂ + 3h ₂ O.

Iingcali musa yaleza ukusebenzisa kugcino cylinder iasithilini zixhotyiswe nge semigudu zobhedu. Eneneni, xa ukwakhiwa ingxubevange equlethe yobhedu. Ekubeni iasithilini afana esebenzayo, oko kungaba asabela kunye nentsimbi. Ngenxa yale fomu ityuwa Uyadubula.

Ukusetyenziswa iasithilini

Iasithilini - into leyo ngokubanzi kusetyenziswa kumacandelo mveliso ezahlukeneyo. Amaninzi, le igesi isetyenziswa ukuvelisa ethyl utywala njengoko izinto eziphambili ekrwada. Ukongeza, i-iasithilini isetyenziswa kwiintlobo ezithile irabha, iiplastiki kunye acetic acid.

igesi Active isetyenziswa ngokubanzi, kwaye ngexesha iintsimbi, kananjalo, ngexesha beyiqangqulula izinyithi ezahlukeneyo. Kufuneka kuqatshelwe ukuba ilangatye strong luqokelelane apha igcwala yi oksijini iasithilini. Gas umthombo ukukhanya ngokwaneleyo Kukhazimlayo, izibane uhlobo elizimeleyo. Ngokusekelwe imveliso iasithilini weziqhushumbisi, ezisetyenziswa ngakumbi njengoko detonators.
