Shiri na methane a cikin gida da kuma a awon yanayi

Methane - colorless iskar gas da cewa konewa tare da blue harshen wuta, babban tsarin bangaren na halitta (77-90%) da kuma free gas ne m.

samar da methane

Ya ce gas ne generated saboda da methane, da sauran iri daban-daban fermentation hanyoyin gudanar da mahadi a ƙarƙashin rinjayar kwayoyin Cellulosae metanicus:

(S6N10O5) nN2O n + - + 3nSN4 3nSO2.

Methane wani lokacin kira fadama gas, tun lokacin da aka kafa a lokacin methane fermentation kwayoyin halitta a kan tushe na halitta da gawawwakin ruwa. Bugu da ƙari kuma, methane da aka samar a cikin hanji da kuma proventriculus dabbobin da muke kiwo dabbobi fermented kayan abinci. Babbar yawa methane aka kafa a pathologies - atony proventriculus, mai guba dyspepsia, ciyar da matalauci ingancin abinci.

Methane ne daya bisa uku na jimlar nauyin proventriculus. Lokacin da Rotting taki na gona da dabbobi nuna manyan yawa na methane, wanda ta hanyar musamman shigarwa an yi amfani for dumama dabbobi gine-gine.

Shiri na methane da thermal refining, iskar gas, da kuma wani hydrogenation koksirovaniya kwal (27-38%) da ake samu gagarumin yawa. Wannan gas Forms da akai na wani yanayi na wasu duniyoyi (Jupiter, Titan, Saturn).

Shiri na methane a cikin gida

Don samun gas dole dauki wasu gona daga kasa fadama da kuma sanya shi a cikin wani gilashi sa'an nan cika da ruwa. Bugu da ari, jita-jita tam stoppered da kuma sanya dumi da kuma duhu wuri. Bayan 'yan kwanaki a kan ruwa surface, za ka lura bayyanar lafiya kumfa. Gas daga bankuna za a iya kasaftawa ta wajen flue ducts.

Shiri na methane a vitro

Kullum, shi aka hada daga sodium acetate a Dumas dauki. Don bushe vial gabatar 10 g wata cakuda wanda kunshi wani sashi na sodium acetate da kuma guda biyu da soda lemun tsami (wani cikakken bayani na sodium hydroxide da alli oxide a cikin wani rabo na 1: 1). A tube aka stoppered tare da wata iskar gas kanti tube da kuma gyarawa zuwa taži. A cakuda shi ne mai tsanani. Ya kamata a lura da cewa na farko tube aka kona, sa'an nan - da cakuda. Methane, wanda aka kafa a wannan na farko saukar a cikin tube da ruwa, sa'an nan kuma ya jũya a cikin shambura cika da mafita na potassium permanganate , da kuma aidin da potassium iodide.

Methane da aka samar daga thermal hydrolysis na sodium acetate da Alkali:

Sodium acetate + sodium hydroxide - sodium carbonate methane +

Shiri na ethylene daga methane

Ethylene - wani muhimmin albarkatun kasa domin samar da polystyrene da polyethylene. Modern masana'antu hanyoyin domin samar da ethylene bisa tururi fatattaka daga haske man fetur. A alamar madadin zuwa kayyade Hanyar iya zama samar da ethylene daga methane. Ba kamar man fetur, iskar gas, da babban tsarin bangaren wanda yake CH4, an dauki matsayin sabunta raw kayan. A wannan yanayin da dauki auku a zazzabi na 500-9000 digiri a gaban O2 da manganese ko oxides na cadmium. A sakamakon gas an raba ta wajen sha, zurfin sanyaya da kuma matsa lamba barasan.

Karkashin awon yanayi, ethylene ta shirya hanyoyin ethanol dehydration da dehydrogenation na ethane. A ethylene za a iya amfani da kira na ethanol, polyethylene, ethylbenzene, vinyl chloride, maganin daskarewa jamiái (abubuwa da rage da sanyinsu na ruwa a cikin injuna) da kuma sauran hanyoyin gudanar da mahadi. A adam da dabbobi magani, ethylene aka yi amfani a matsayin narcotic miyagun ƙwayoyi, a shuka - don bugun sama da ripening 'ya'yan itatuwa (lemu, lemons, tumatir, ayaba, grapefruits, da dai sauransu).

A amfani da methane

Bugu da ƙari kuma, methane - mai muhimmanci da man fetur, shi ma ne a albarkatun kasa domin samar da methyl barasa, chloroform, formaldehyde, robobi, da dai sauransu Hada daga methane, acetylene da sauran mahadi.
