Sida loo helo ka methane, alxamaad

Si aad u hesho methane of alxamaad, waxaa lagama maarmaan ah si ay u qabtaan reaction dehydrogenation. Inta aad guda galin ay dib u eegis, falanqaynta qaar ka mid ah shidaalka gaar ah.

Astaamaha u gaarka ah alxamaad

walax Tani gaseous, taas oo ah wakiilka koowaad ee fasalka ka mid ah Consort roodhida (alkynes). Waa xumbo hawada, waa liidata L. biyo. Kelli formula C ₂ H _2, caadi ah in fasalka oo dhan SPN ₂ n-2. Alxamaad waxaa loo arkaa kiimikada firfircoon, oo ayan ku jirin aad u qarxa. Si looga fogaado xaaladaha degdegga ah, waxaa lagu kaydiyaa weel bir shaabadeeyey, isagoo intaa ku daray in ay dhuxusha.

Helitaanka ka alkanes

daatay Marka of alxamaad methane helay. reaction kiimikada Tani waxaa lagu fuliyaa iyadoo la isticmaalayo Hannaan dhacdaa heerkulka kacsantahay. Qoraalkani wuxuu ku bilaabin taagan heerka koowaad paraffins wakiil. Marka dehydrogenation, Intaa waxaa dheer ee alxamaad, hydrogen ahbaa.

Ka jawaabaya su'aal ku saabsan sida aad u heli ka methane, alxamaad, isla'egta falcelinta ka wakiil yahay in foomka:

2SN4 = C2H2 + 3H2

habka carbide

Mid ka mid ah ka heli kartaa methane ama alxamaad sida wax ka billaabayso in aad qaadato carbide calcium ah. Geedi socodka qaadataa meel ku hoos jira xaalad daarmayaay'e. In falcelinta ee carbide calcium biyo la aasaasay ma aha oo kaliya alxamaad, laakiin hydroxide calcium (lime cabbid). Astaamaha duuli doona horumar gaaska habka kiimikada (foodhyi), iyo isbedelka midabka ah ee xalka by daray phenolphthalein on midabka casaanka ah.

Marka aad codsanayso sidii wax bilaabo carbide farsamo isagoo nijaasta kala duwan, ur arkay inta lagu guda jiro dareen-celinta. Wuxuu by joogitaanka ee wax soo saarka dareen-celin ah gaasaska sunta ah sida phosphine, tayadda hydrogen sharaxay.

petroleum arrinkaas

Currently, aadan heli karin oo kaliya baxay methane, alxamaad. Habka ugu weyn ee warshadaha wax soo saarka ee wakiilka of alkyne waxaa loo arkaa in ay arrinkaas (cholesterol) oo hydrocarbon ah. Haddii methane heli alxamaad, qiimaha tamarta noqon doonaa yar. Waxa intaa dheer in alaabta ceeriin aan qaali ahayn oo si sahlan loo heli karo, technology this ayaa soo jiitay soo saarayaasha ee Consort daacad ah qalabka farsamada loo isticmaalo dehydrogenation ee methane.

Waxaa jira laba nooc oo habka kiimikaad la mid ah. Habka koowaad ku salaysan yahay marayay methane dhex maray electrodes, kulul 1600 degrees Celsius. farsamada ay ku lug leedahay demin sheyga sababtay. dehydrogenation muuqashadii labaad ee methane in ay soo saaraan alxamaad ku lug leedahay isticmaalka tamarta, kaasoo lagu soo saaro by sari qayb ka mid ah alkyne ah.

Dhululubada ay ku jiraan alxamaad, ma in lagu qalabeeyaa karaa filtarka naxaas ah, sida qeyb ka mid ah Maarta ah ee ku jira copper. dhexgalka ee biraha la dhalidda alxamaad waxaa ku weheliyay cusbo qarxa.

gunaanad

Alxamaad waxaa hadda la isticmaalo ee beeraha warshadaha kala duwan. Waa wax qiimo leh sida xawliga ah u ereygu wuxuu ahaa ee ethanol, bacyaal, masaxado, acid acetic. Wakiilka of class this sheegtay alkynes for jarida iyo alxanka Biraha, sida iftiinka dhalaalaya ee kulan nalalka shaqsi.

On ku salaysan Avv alxamaad waxaa lagu fuliyaa waxyaabaha qarxa loo adeegsaday qaab qarxa. falcelinta qayilo ee alkyne ee oxygen hawada lagu arkay olol xoog leh. Isku qiimo yahay warshadaha kiimikada iyo methane. Ka sokow in ay codsiga qalab bilaabin wax soo saarka ee alxamaad, waxaa la wada baabbi'iyey tiro badan sida shidaalka dabiiciga ah ee warshadaha shidaalka. Marka gubay qoondeeyay qadar weyn oo kulaylka.
