Pehea e loaʻa mai ka methane, acetylene

I mea e loaa methane o acetylene, ia mea pono e hoʻomaka dehydrogenation naoh. Ma mua ee makou ma luna o kona loiloi 'ia, kālailai kekahi mau hydrocarbon.

Ano o ka acetylene

Kēia gaseous waiwai, i mea ka mua 'elele o ka papa o unsaturated hydrocarbons (alkynes). Ua mea māmā ma mua o ka ea ole, o poorly wailana i loko o ka wai. Hakakino haʻilula C ₂ H _2, he pono ole i ka mea holoʻokoʻa papa SPN ₂ N-2. Acetylene ua eu Nine Inch, he okoa loa pahū. I mea e pale aku pilikia wahi, i hiki, ka mea, ua hūnāʻia i loko o ka wepa kila ipu, ohui ia ia charcoal.

Kaniak mai alkanes

Ma ka decomposition o methane acetylene loaa. Kēia Nine Inch naoh ua lawe mai ka hoʻohana 'ana i ka hōʻeleu ia lŘlŘ ma ka ke kiekie ana wela. Ka hoʻomaka lako e ku mua ka papa 'elele paraffins. I ka dehydrogenation, mawaho o ka acetylene, hydrogen ua ua loaʻa.

Ke paneʻana i ka ninau e pili ana pehea e loaa mai methane, acetylene, ka naoh helu kaulike ua poe i loko o ka palapala:

2SN4 = C2H2 + 3H2

carbide hana

Kekahi e kiʻi mai methane paha acetylene like me ka hoʻomaka mea, e lawe i ke kalipuna carbide. Ke kaʻina hana i wahi ma lalo o Ambient ana. Ma ka naoh o ke kalipuna carbide me ka wai, ua hana ole wale acetylene, akā, kalipuna hydroxide (slaked Lime). Symptoms e kahe ana Nine Inch kaʻina kinoea evolution (kāhāhā aku), a me ka loli ma ka ano o ka pāʻoihana ma ka pepa phenolphthalein ma ka ulaula waihoʻoluʻu.

I ka ana me ho mea he oaoieei-carbide ka likeʻole impurities, ala ike i ka naoh. He wehewehe ma ke alo i loko o ka naoh nā huahana o ka kinoea make i phosphine, hydrogen sulfide.

ʻaila kāʻuʻina

Currently, e hiki ole wale kiʻi mai o methane, acetylene. I ka papa kuhikuhiE hanalima iaoia o? Iecaianoaaiiuo o ka 'elele o ka alkyne ua manaoia i ńlua (cleavage) o hydrocarbons. Inā methane loaa acetylene, ka ikehu koina e e ka palena haʻahaʻa. Ma waho aʻeo ia inexpensive a me ka hana i loaʻa maka mea, 'ike loea keia ua o Laielohelohe nā hoʻohua o hydrocarbons ke akahai oʻanoʻenehana lako a hoʻohana' ia i loko o ka dehydrogenation o methane.

Aia he mau wale nō o ka like Nine Inch kaʻina. Ka papa hana mua ua muli i hele i ka methane ma na nā uila aʻa lolo, wela i ka 1600 kekelē Kelekia. Keʻano hana komo ai I hoopio ai hoi i ka resultant huahana. Luaʻano dehydrogenation o ka methane e paka acetylene komo ai i ka hoʻohana 'ana o ka ikehu, a ua hua mai ma ka hapa'ā o ka alkyne.

Nā paukūʻolokaʻa i pihaʻi me acetylene, hiki ole ke hoʻolako pono me ka keleawe kiwikā, me kekahi hapa o ke keleawe, he keleawe. Ke AaOIeIOUIeXAOAaIN o ka metala me ka acetylene hua ua pu ma ka pahū paʻakai.

ka hopena

Acetylene ua a ianoiyuaa a hoʻohana 'ia i loko o nā hanalima kula. He He waiwai nui maka mea no ka hoʻololi kemikala o ethanol, Ka lula ea Ke, rubbers, aceticʻakika. Lunamakaainana o keia ano koi alkynes no ka oki a me ka kuʻihao i eliiaʻi, e like me ka huali kukui i loko o ka kanaka kau iho fixtures.

Ma ke kumu o acetylene hoʻololi kemikala ua lawe pahū hoʻohana 'ia i loko o ka palapala o detonators. Ke'okesaside naoh o ka alkyne o ka o oxygen ma ka lewa ua mālama i ka ikaika lapalapa. O like waiwai o ka Nine Inch hana a me ka methane. Ma waho kona palapala noi i ka hoʻomaka mea no ka? Iecaianoaaiiie o acetylene, ka mea, ua lukuʻia i loko o nui mea like me ka hydrocarbon maoli i loko o ka wahie oihana puolo. I ka wa i kuni ai anao? Aou he nui nui o ka wela.
