Sezvo acetylene rakagadzirirwa kubva methane

Acetylene iri fuma kungova boka alkynes. Nemamwe mashoko, yeHydrocarbon rine neimwe morekuru chisungo katatu. In ichi kwemakemikari payakavakirwa acetylene sezvinotevera: C ₂ H _2. Pacharo, fuma iri Hauoneki gasi, inova vakareruka kupfuura mhepo. Acetylene akawana kubva methane. The fuma iri reactive uye putika.

How kuwana acetylene

Of methane mumba kuti vawane acetylene zvakaoma chaizvo. Nyore nzira nokuda voga pakati gasi - mvura iyi zvaanoita pamwe karusiyamu carbide. Vazhinji venyu pamwe rangarirai sei kukanda mu puddles zvipenga zvacho uye chii kuita kunoitika. Yakati kufambira shinyira. Kana karusiyamu carbide, ipapo zvishoma nezvishoma ikavhunduka, pova zvizhinji furo. Zvakafanana zvinogona kunyorwa se:

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

Vazhinji hwokugadzira karusiyamu carbide rinoshandiswa, iyo ine yakawanda tsvina. Somugumisiro, maitiro acho nemvura anosunungura kwakanaka yakaipa. It zvauya kubva maumbirwo, pamwe chete zviduku mari acetylene negasi chepfu vapor. Kakawanda iri phosphine, rehydrogen sulfide, uye zvichingodaro. Nzira iyi ndicho, sezvo kuwana acetylene kubva methane zvinogoneka chete rinokosha michina.

Preparation Industry

How kuwana acetylene kubva methane mu muindasitiri ezvinhu? Pari kushandiswa mumwe chete nzira - Cracking. Panguva pakugadzirira acetylene rinoitwa decoupling -C-C. Izvi zvinoitika pamberi catalysts uye pane imwe zvakakwana yakakwirira tembiricha chokupfeka. For anoshandisa methane - negasi. Izvi isingadhuri uye nyore mbishi zvinhu. It iri chikonzero kuti Cracking ndiyo nzira inogutsa zvose mune zvoupfumi uye magadzirirwo.

Sei wakatsemuka

Kuti aite kutendeuka "methane - acetylene" nenzira dzakawanda. Muchiitiko chokutanga, negasi iri vakayambuka pre-inopisa electrode. The tembiricha inogona kusvika kusvika 1600 ° C. Mushure kudziyisa, nokukurumidza kutonhora kunoitika. The Nzira yechipiri kunobva pakushandisa kupisa kuti vanowanika nokuda haasaruri combustion kuti acetylene.

Zvaakazoita mukana wokuti vanhu vanga "methane - acetylene" zvakanyorwa sezvinotevera:

1. Kana I: 2Mak ₄ = C ₂ H ₂ + 3 _2.

1. Kana II: 6SN ₄ + 4O ₂ = C ₂ H ₂ + 8H + 3Saka ₂ + CO ₂ + 3 ₂ O.

Nyanzvi regai kuvakurudzira kushandisa kuchengetera acetylene sepombi vakapakata mavharuvhu nendarira. Zvechokwadi, muna Kuronga chiwanikwa ine mhangura. Sezvo acetylene mishonga kushingaira, unogona sei pamwe simbi. Somugumisiro ichi fomu putika munyu.

Kushandiswa acetylene

Acetylene - a fuma kuti zvinowanzoshandiswa siyana maindasitiri sectors. Kakawanda, gasi ichi rinoshandiswa kugadzirwa ethyl doro sezvo huru mbishi zvinhu. Mukuwedzera, acetylene inoshandiswa nokuda mamwe rabha, mapurasitiki uye acetic acid.

rinoshandiswa Active gasi nevakawanda, uye panguva nomoto, uye kana achicheka simbi dzakasiyana. Zvinofanira kucherechedzwa kuti simba murazvo achiumbwa munyika oxidation kubudikidza okisijeni acetylene. Gas kunobva chiedza zvakakwana chinopenya mwenje ose zvionera mhando. Based acetylene zvibereko zvinoputika, ayo mamwe kushandiswa detonators.
