Nkwadebe nke methane ke ufọk na laabu ọnọdụ

Methane - colorless gas na-enwu enwu na a-acha anụnụ anụnụ ire ọkụ, isi bughi akụrụngwa nke eke (77-90%) na free gas bụ na-agbawa agbawa.

mmepụta nke methane

Sị na gas na-eme n'ihi na methane, na ndị ọzọ na iche iche iche iche nke gbaa ụka nke organic ogige n'okpuru nduzi nke bacteria Cellulosae metanicus:

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

Methane-akpọ mgbe ụfọdụ apiti gas, ebe ọ bụ na a kpụrụ n'oge methane gbaa ụka nke organic okwu na ala nke eke ozu mmiri. Ọzọkwa, methane na-emepụta na eriri afọ na proventriculus ruminant anụmanụ fermented akwukwo nri nri. Nnukwu ichekwa methane ii na pathologies - atony proventriculus, nsí dyspepsia, udia ogbenye mma ndepụta.

Methane bụ otu ụzọ n'ụzọ atọ nke ngụkọta nke ịdị arọ nke proventriculus. Mgbe rere ere nsị anụ nke anụmanụ na-emepụta nnukwu quantities nke methane, nke site pụrụ iche nrụnye na-eji kpo oku nke anụ ụlọ ụlọ.

Nkwadebe nke methane site thermal ejegharịrị, eke gas, na a hydrogenation koksirovaniya coal (27-38%) amịrị ịrịba quantities. Nke a gas Nleta ndabere nke ihe ikuku nke ụfọdụ mbara ala (Jupiter, Titan, Saturn).

Nkwadebe nke methane ke ufọk

Iji nweta gas mkpa iji ụfọdụ ala na ala nke apiti na-etinye ya na a ite na mgbe jupụta na mmiri. Ọzọkwa efere tightly stoppered ma dọba-ekpo ọkụ na n'ebe gbara ọchịchịrị. Mgbe ụbọchị ole na ole na mmiri n'elu, ị ga-achọpụta na onye ahụ nke ezi egosipụta. Gas si mmiri nwere ike ekenyela site flue ducts.

Nkwadebe nke methane na vitro

N'ozuzu ya, e synthesized si sodium acetate na Dumas mmeghachi omume. Iji a akọrọ mkpọ ẹkenam 10 g nke a ngwakọta nke bụ otu akụkụ nke sodium acetate na abụọ iberibe soda lime (a jupụta ngwọta nke sodium hydroxide na calcium oxide na a ruru nke 1: 1). The tube e stoppered na a gas tinyekwa tube na ofu aka tripod. Ngwakọta bụ kpụ ọkụ n'ọnụ. Ọ ga-kwuru na mbụ na nke tube na-ewe iwe, wee - ngwakọta. Methane, nke a kpụrụ na mbụ a lowered n'ime tube na mmiri na mgbe amama n'ime akpa jupụtara na ngwọta nke potassium permanganate , na ayodiin na potassium iodide.

Methane na-emepụta si thermal hydrolysis nke sodium acetate na alkali:

Sodium acetate + sodium hydroxide - sodium carbonate methane +

Nkwadebe nke ethylene si methane

Ethylene - otu ihe dị mkpa akụrụngwa n'ihi amị polystyrene na polyethylene. Modern ulo oru ụzọ amị ethylene dabeere na n'elu uzuoku cracking nke ìhè na mmanụ. A ekwe ọzọ ka kpọmkwem usoro nwere ike ịbụ na mmepụta nke ethylene si methane. N'adịghị ka mmanụ ala, eke gas, isi bughi akụrụngwa nke nke bụ CH4, a na-ewere dị ka ndị mmeghari ngwaọrụ. Na nke a mmeghachi omume n'abu a okpomọkụ nke 500-9000 degrees n'iru O2 na manganese ma ọ bụ oxides nke cadmium. Ihe gas na-iche site n'aka absorption, miri jụrụ na mgbali distillation.

N'okpuru laabu ọnọdụ, ethylene kwadebere site ụzọ ethanol akpịrị ịkpọ nkụ na dehydrogenation nke ethane. The ethylene mee ihe njikọ nke ethanol, polyethylene, ethylbenzene, vinyl chloride, antifirizi elekọta mmadụ (bekee nke belata kefriza ebe mmiri na engines) na ndị ọzọ organic ogige. Na mmadụ na ọgwụgwọ ọrịa anụmanụ na nkà mmụta ọgwụ, ethylene eji dị a narcotic ọgwụ, na osisi - na adị chaa mkpụrụ osisi (oroma, lemons, tomato, unere, grapefruits, wdg).

The ojiji nke methane

Ọzọkwa, methane - a bara uru mmanụ ụgbọala, ọ bu kwa ihe-a akụrụngwa n'ihi amị methyl mmanya, chloroform, formaldehyde, plastik, wdg Synthesized si methane, acetylene na ndị ọzọ na ogige.
