Yadda za a samu daga methane, acetylene

Domin samun methane da acetylene, shi wajibi ne su gudanar da dehydrogenation dauki. Kafin nazari a kan ta review, bincika wasu musamman hydrocarbon.

Halaye na acetylene

Wannan gaseous abu, wanda shi ne na farko wakilin wani aji na unsaturated hydrocarbons (alkynes). Shi ne m fiye da iska, shi ne talauci mai narkewa a cikin ruwa. Kwayoyin dabara C ₂ H _2, kowa ga dukan aji SPN ₂ n-2. Acetylene aka dauke aiki sunadarai, kuma musamman m. Domin kauce wa gaggawa yanayi, shi ne adana a hatimce karfe kwantena, kara zuwa da shi gawayi.

Samun daga alkanes

Bayan bazuwar na methane acetylene samu. Wannan sunadarai dauki ne da za'ayi amfani da wani mai kara kuzari auku a wani dagagge zafin jiki. A fara abu tsaye farko aji wakilin paraffins. Lokacin da dehydrogenation, Bugu da kari na acetylene, hydrogen da aka generated.

Amsawa ga wata tambaya game da yadda za a samu daga methane, acetylene, da dauki lissafi aka wakilta a cikin hanyar:

2SN4 = C2H2 + 3H2

carbide hanyar

Daya iya samun daga methane ko acetylene matsayin fara abu ya dauki alli carbide. A tsari faruwa a karkashin yanayi na yanayi. A dauki alli carbide da ruwa da aka kafa ba kawai acetylene, amma alli hydroxide (slaked lemun tsami). Alamun sunã gudãna daga tsarin sunadarai gas juyin halitta (tsaki), da kuma canji a cikin launi daga cikin bayani ta ƙara phenolphthalein a kan wani garura launi.

Lokacin da ake ji kamar fara abu mai fasaha carbide da ciwon daban-daban impurities, wari lura a lokacin da dauki. Ya bayyana ta gaban a dauki kayayyakin da irin wannan m gas kamar yadda phosphine, hydrogen sulfide.

man fetur fatattaka

A halin yanzu, ba za ka iya kawai fita daga methane, acetylene. Babban masana'antu Hanyar samar da wakilin alkyne aka dauke su fatattaka (tsakiyan nonon) na hydrocarbons. Idan methane sami acetylene, da makamashi ta halin kaka zai kasance kadan. Bugu da kari ga m da kuma samuwa albarkatun kasa, wannan fasahar ta janyo hankalin masu kera na hydrocarbons sauki fasaha kayan aiki amfani a cikin dehydrogenation na methane.

Akwai iri biyu na irin wannan tsarin sunadarai. A farko hanyar dogara ne a kan wucewa da methane ta hanyar da wayoyin, zafi zuwa 1600 digiri Celsius. Da dabara ya shafi quenching da resultant samfurin. Biyu rungumi dehydrogenation na methane ya nuna acetylene shafi yin amfani da makamashi, wanda aka samar da m konewa na alkyne.

Cylinders dake dauke da acetylene, ba za a iya sanye take da tagulla bawuloli, kamar yadda wani ɓangare na Bronze ƙunshi tagulla. The hulda na karfe tare da acetylene amfanin ƙasa yana tare da m gishiri.

ƙarshe

Acetylene halin yanzu ana amfani da daban-daban da masana'antu a filayen. Shi ne mai muhimmanci da albarkatun kasa domin kira na ethanol, robobi, rubbers, acetic acid. Wakilin wannan aji da'awar alkynes ga yankan da kuma waldi karafa, kamar yadda haske a cikin mutum lighting maras motsi.

A kan tushen da acetylene kira ne da za'ayi nakiyoyi amfani a cikin nau'i na detonators. A hadawan abu da iskar shaka dauki na alkyne na oxygen a iska an lura mai karfi harshen wuta. Na daidaita darajar ne sinadaran masana'antu da methane. Bayan da aikace-aikace a matsayin fara abu domin samar da acetylene, shi ne cinyewa a cikin manyan yawa a matsayin halitta hydrocarbon a cikin man fetur masana'antu. Lokacin da kone kasaftawa wani gagarumin adadin zafi.
