Njengoba acetylene yalungiswa kusukela methane

Acetylene kuyinto into okuqondene ekilasini alkynes. Ngamanye amazwi, lo hydrocarbon eyabika esikhathini ngalinye elithwala isibopho kathathu. Kulesi chemical ifomula acetylene kanje: C ₂ H _2. Ngokwaso yalolu ketshezi yigesi kungekho nto enemibala emihle, ngiyiphi elula khulu kakhulu kuka air. Acetylene eyatholakala kusukela methane. Ingqikithi kuyinto esisheshayo futhi kuqhume.

Ingatholakala kanjani acetylene

Methane ekhaya ukuze uthole acetylene kunzima kakhulu. Indlela elula kakhulu inyumbazana ngenxa igesi - manzi ixubana Carbide calcium. Abaningi cishe ukukhumbula ukuthi baphonse in amaxhaphozi izingcezu ketshezi futhi yini ukusabela kwenzeka. Kwaphawulwa le shweza okusheshayo. Njengoba for calcium Carbide, khona-ke kancane kancane elicibilikile, ukwakha nenani elikhulu Foam. A ukusabela okufanayo singatlolwa bunjesi:

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

Abaningi lobuchwepheshe calcium Carbide isetshenziswa, equkethe semali amanyela. Ngenxa yalokho, indaba ukuphendula amanzi kudedela iphunga ezimbi. It kuvela kusukela ekwakhekeni, kanye nenani ezincane igesi acetylene evala anobuthi. Ngokuvamile kuba phosphine, hydrogen sulfide nokunye. Le ndlela iyona ezivamile, njengoba ukuthola acetylene kusukela methane kungenzeka kuphela imishini ekhethekile.

Ukulungiselela Imboni

Kanjani ukuze uthole acetylene kusukela methane isimo zezimboni? Okwamanje wasebenzisa indlela eyodwa kuphela - ngokuhlaziya. Phakathi ukulungiswa acetylene is wayebaphathele decoupling -C-C. Lokhu kwenzeka ngo-khona catalysts futhi ngesikhathi sezingeni eliphezulu lokushisa ukuchayeka. Ukuze usebenzisa i-methane - igesi yemvelo. Lena izinto zokusetshenziswa engabizi futhi lutholakale kalula. Kungenxa yalesi sizathu ukuthi kwemifantu iyona ndlela enengqondo kunazo kokubili umnotho kanye nomsebenzi.

odabukileyo kanjani

Ukuze afeze ukuguqulwa "methane - acetylene" ngezindlela eziningi. Esimweni sokuqala, igesi yemvelo ihamba badabula electrode pre-hot. Amazinga afinyelela 1600 ° C. Ngemva Ukushisa, Ukupholisa okusheshayo kwenzeka. Eyesibili indlela kusekelwe ukusetshenziswa ukushisa ekhiqizwa yi-amandla omlilo olungaphelele acetylene.

Ukusabela equation "methane - acetylene" zilotshiwe kanje:

1. Uma mina: 2Kro ₄ = C ₂ H ₂ + 3H _2.

1. Uma kwenzeka II: 6SN ₄ + 4O ₂ = C ₂ H ₂ + 8H + 3Ngako ₂ + CO ₂ + 3H ₂ O.

Ochwepheshe batusa ukusebenzisa isitoreji amasilinda acetylene ifakwe valve wethusi. Ngempela, indlela yokwakheka ingxubevange equkethe zethusi. Njengoba acetylene amakhemikhali asebenzayo, kungaba ukuxubana kwensimbi. Ngenxa yalokho leli fomu usawoti alufakwa.

Ukusetshenziswa acetylene

Acetylene - ikhemikhali kabanzi kwimikhakha yezimboni eyahlukene. Ngokuvamile, le gesi isetshenziswa ekukhiqizeni ETHYL utshwala njengoba impahla eluhlaza main. Ngaphezu kwalokho, acetylene isetshenziswa sezinhlobo ezithile iraba, epulasitikini futhi acetic acid.

igesi Active sisetshenziswa kabanzi, futhi ngesikhathi Welding, futhi lapho ukusika ngezinto ezihlukahlukene. Kufanele kuqashelwe ukuthi kwakhiwa ilangabi obuqinile kule namachibi ngu-mpilo acetylene. umthombo negesi ungukukhanya ngokwanele elikhanyayo izibani ohlobo ezizimele. Isekelwe acetylene umkhiqizo iziqhumane, iziphi eminye esetshenziswa njengoba detonators.
