Sei kubva methane, acetylene

Kuti vawane methane pamusoro acetylene, zvakafanira kuti kuitisa dehydrogenation kuita. Vasati vatanga ayo review, ongorora zvimwe kunyanya yeHydrocarbon.

Zvinoitwa acetylene

Ichi gaseous fuma, inova mumiririri boka unsaturated Mahydrocarbon (alkynes) rokutanga. Zviri vakareruka kupfuura mhepo, uri havaratidzi soluble mumvura. Molecular payakavakirwa C ₂ H _2, zvakajairika yose kirasi SPN ₂ N-2. Acetylene anonzi vanoshingaira makemikari, kunze zvikuru putika. Kuitira kudzivisa zvashata ezvinhu, zvinonzi inochengetwa chisimbiso simbi midziyo, achiwedzera kwairi nemarasha.

Kuwana kubva alkanes

Pamusoro manyowa kubva methane acetylene yapihwa. Izvi kwemakemikari kuita rinoitwa kushandisa anowedzera ndepana ane tembiricha yakakwirira. The kutanga zvinhu inomira kirasi yokutanga mumiririri paraffins. Kana dehydrogenation, kuwedzera acetylene, rehydrogen riri kunotangira.

Achipindura mubvunzo sei kuti kubva methane, acetylene, maitiro mukana wokuti vanhu vanga rinomiririrwa muchimiro:

2SN4 = C2H2 + 3H2

carbide nzira

Mumwe anogona kuwana kubva methane kana acetylene sezvo kutanga mashoko kutora mashoko karusiyamu carbide. The kwacho kunoitika pasi ambient ezvinhu. In zvakaitwa calcium carbide nemvura aumbwa kwete acetylene chete, asi karusiyamu hydroxide (slaked madota). Zviratidzo dzichayerera kwemakemikari muitiro gasi shanduka (muridzo), uye kuchinja ruvara chemhinduro nokuwedzera phenolphthalein pamusoro tsvuku ruvara.

Kana kushandisa sezvo pokutangira zvinhu waishandiswa carbide ane tsvina siyana, kwakanaka kwakacherechedzwa mumakore kuita. Akatsanangura nokuvapo ari maitiro zvibereko dzakadai chepfu magasi sezvo phosphine, rehydrogen sulfide.

peturu Cracking

Pari, haugoni chete kubuda methane, acetylene. Nzira huru maindasitiri okuwana ari mumiririri alkyne runoonekwa kuti cracking walnut (cleavage) pakati Mahydrocarbon. Kana methane vanogamuchira acetylene, simba mari vachava usingashandi. Mukuwedzera chipa uye nyore pakugadzira zvinhu, ruzivo urwu kukwezvwa Vanoburitsa Mahydrocarbon nyore muzvigadzirwa midziyo yaishandiswa dehydrogenation pamusoro methane.

Pane shanduro mbiri makemikari kwacho zvakafanana. nzira yokutanga kunobva nepamahofisi methane kuburikidza electrodes, kupisa kusvika 1600 Celsius. Nzira kunosanganisira richipedza Pamusana chigadzirwa. Second musimboti dehydrogenation kuti methane kuti vabereke acetylene kunosanganisira kushandisa simba, iro zvinoberekwa rushoma combustion yacho alkyne.

Sepombi kuti ane acetylene, haagoni vakagadzirira pamwe mavharuvhu nendarira, sezvo chikamu Bronze rine mhangura. The kukurukurirana pamusoro simbi pamwe acetylene goho achabatsirwa putika munyu.

mhedziso

Acetylene iri pari kushandiswa siyana maindasitiri minda. Chinhu chinokosha mbishi zvinhu nokuda kwetunhu panyaya iyi, mapurasitiki, rubbers, acetic acid. Mumiririri mukirasi iyi vaiti alkynes kuti kucheka nomoto nesimbi, sezvo chiedza muna nomumwe chiedza Fixtures.

Pahwaro acetylene kwetunhu rinoitwa zvinoputika rakashandiswa muchimiro detonators. The oxidation maitiro alkyne reokisijeni mumhepo iri akaona simba womoto. Adzikinure ndiye zvemakemikari bhizimisi uye methane. Kunze kushandisirwa sechinhu kutanga mashoko kugadzirwa acetylene, zviri kuparadzwa akawanda sechinhu dzinongoitika yeHydrocarbon ari mafuta indasitiri. Kana kupiswa dzinounzwa inokosha mari kupisa.
