Methane, alxamaad waxaa loo isticmaalaa in kala duwan oo dareen diidmo oo la qiimo warshadaha

In liiska Consort, methane, alxamaad, ka ciyaaraan door muhiim ah ka meelo kala duwan oo warshadaha kiimikada. Markii hore methane ma matalaan kasta oo dan ku ool ah. Waxa uu la odhan jiray oo dhiiqo iyo qoyan meeshii waxay inta badan waxaa laga helaa dabiicadda. Caadi ahaan, xarunta this siiyey dhibaato badan sababta oo ah guryaha jireed iyo kiimikada. methane midab iyo ur keeni karaa qof oo yar indisposition ah, iyo xataa lagu sumoobo daran. Laakiin dhibaato aad u badan ay awood u keeni gaaska qasan hawada si ay u sameeyaan is biirsaday ololi kara la kartida burbur weyn.

In kasta oo xaqiiqda ah in methane helay siyaabo badan si ay u isticmaalaan, wax soo saarka ee walax this by warshadaha waa waxtar lahayn. Xaqiiqada ah in la xidhiidha tani ma aha oo kaliya caadiga ah ee dabiiciga ah, laakiin waa saaxiibka (dhinac) alaabta ee geedi socodka kala duwan farsamada warshadaha kiimikada casriga ah.

Berthelot ee 1860, wuxuu ahaa awoodaan si ay u fuliyaan falcelinta, taasi oo markii dambe heshay muhiimada warshadaha weyn. Laakiin wakhtigaas, habka u ogolaanaya in ay fuliyaan methane a wareejin kiimikada> alxamaad, ma helin xamaasad badan. Xaqiiqada ah in baahida loo qabo in halkaas loo xaqiijiyo waa ku filan tahay in carbide alxamaad iyo habka ay wax soo saarka.

warshadaha kiimikada Modern ayaa helay siyaabo badan oo ay isticmaali of alxamaad. goynta gaaska Tani, oo aad u isticmaasho in laambadihii kiimikada dhalaalaya, oo loo isticmaalo soo saaridda ee kala duwan ee kiimikada. Alxamaad sheegtay in helitaanka kala duwan oo xeryahooda qarxa iyo acetic acid, ethyl khamriga iyo qase, caag iyo Consort leedahay beduliyum. muujinta A oo ka mid ah guulaha ee qarnigii labaatanaad ahaa isticmaalka alxamaad in wax soo saarka ee polymers.

wakhti ah in la xasuusto beddelidda kiimikada ee methane - alxamaad. Elektrokreking iyo arrinkaas thermo-murqo - magaca hababka casriga ah farsamada oo keeni waa alxamaad ka methane. In kiiska hore, jet gaaska methane ka maraa electrodes hoostiisa heerkulka 1600 ° C iyo si degdeg ah la qaboojiyey. Hirgelinta habka labaad ee diinta methane - alxamaad, qayilo qayb ahaan, janjeero sii daayo kulaylka ka sari ee qayb ka mid ah alxamaad ah.

In silsilad soo saarka, methane, alxamaad, acetaldehyde item la soo dhaafay waxay ku yimaadeen reaction fuuq of alxamaad, kaas oo markii danbe loo yaqaan reaction Kucherov. Industrial Applicability acetaldehyde helay wax soo saarka ee acid acetic, polymers aldehyde, tirada butadiene walxaha organic.

Laakiin walax laftiisa waa ammaan ahayn, acetaldehyde xad sun ah xitaa marka codsatay in ay maqaarka. Guddoomiyaha pollutant hawada halis ah, taas oo u xiisay ee gubashadeeda, tusaale ahaan, by sigaarka ama qiiqa baabuurta. Xaddi weyn waxaa ka mid ah waxaa la aasaasay by daaweyn kulaylka of polymers kala duwan iyo bacyaal.

methane silsilad Next, alxamaad, benzene, chlorobenzene waa xaqiijin dheeraad ah isticmaalka firfircoon ee warshadaha kiimikada casriga dhiiqo ama firedamp. Waxaan hore u yaqaanaan dareen diidmo ka saaro alxamaad ah. Waxaa weli kaliya si ay u fuliyaan trimerization ee gaaska this, C2H2 maraya dhuxusha firfircoonaan heerkulka a of 400 degrees Celsius. taasoo keentay habka warshadaha wax soo saarka ee benzene tagaa ethylbenzene, cumene, nitrobenzene iyo cyclohexane. About saddex boqolkiiba oo ah walaxda waa la wada baabbi'iyey in diyaarinta benzenes alkyl toosan. Kaliya hal boqolkiiba isticmaalka benzene, waayo, Avv chlorobenzene. Ujeedada this, falcelinta ee ay koloriin. Xaaladaha of hirgelintiisa waa heerkulka at 80-85 ° C iyo joogitaanka bir ah ama chloride bir ah.
