Ke? Iecaianoaaiiie o acetylene

Oiaio loa na kanaka ike i ka olelo - acetylene - ua hoʻopili i ka manaʻo o "vīnega". Akā, i ka mea i acetylene i keia la - ka mea, o ka mea wale nō ka waiwai i ke puhi ia i ka lewa i 'ae', a i ua hoʻomano hoʻohana ma o ka hana, i ike ole a pau. Acetylene pilikia aʻo nui mea no hoi ia i ka mea e, no ka laʻana, kona aa ana produces lapalapaʻakika mahana i ka 3100 ° C.

No ka mea manawa mua i lawe mai? Iecaianoaaiiuo o acetylene Edmundom Devi i loko o ka mamao 1836. Devi hana iʻike mau carbide potasiuma koʻana koko pāʻoihana mai ai i ka naoh helu kaulike i hiki ke palapala like: k2c2 = C2H2 + 2H2O + 2KOH. E like me ka hopena, he kinoea, nona ka haʻilula o C2H2, a ma ka noiʻi i inoa dvuuglerodisty hydrogen.

Me ka loaʻa o ke aʻo o ka radicals Iouseto kona Liebig kekahi o nā pūʻulu o nā'ātoma (radicals) a ua kapaʻia acetyl, nae, ka mea, ua manaoia he huina lakou o ka haʻilula S2N3. Ka waiwai o ka mea hookahi, a ua Devi, i manaʻoʻia chemists like me ka derivative o acetyl. A laila, i ka wa a ka? Iecaianoaaiiie o acetylene i laweia mai ma Farani Marselenom Berthelot i loko o kekahi mau aoao, ka waiwai la kona inoa, a ua hoʻohana 'ia i loko o kemika a hiki i kēia lā. Berthelot noʻonoʻo me ka lātoma kūpono hui acetyl, i i laweʻia, mai ka hydrogen'Ātoma. Technologically, i ka makaukau o acetylene Berthelot ho i ka mea e hiki mai ana kaʻina. Ua lilo kekahi paʻa o ka wela a ka waiʻona i - meto a me ka'eto - no hoi ma o ka hahana loa paipu a hiki i ka wela kiʻekiʻe.

I kekahi mau mea ma hope, i ka 1862, i synthesized ma ka electrochemical naoh, oiai i hydrogen i hele ma waena o nā nā uila aʻa lolo i o kalapona acetylene. Mau loea i i ka manawa a pau loa pipiʻi, a inefficient, a no ia mea hiki wale ke manao like me kaʻimi naʻauao pāʻoihana i ka pilikia. Wale nō ma ka loa hopena o ke kenekulia mua hope i invented i kekahi papa hana i 'ae' e hookupaa i oi ka hoʻokele waiwai? Iecaianoaaiiuo o acetylene. Kēia papa hana ua muli ma luna o ka mea hō'ā kaʻa o ka läÿau, iloko olaila no ka poe ola, Lime a me ka lanahu. Kēia e alakaʻi ana i ka hoʻohana 'ana i ka hui i ke kinoea i alanui kau iho. Ka mea i ke kinoea i kekahi i loko o kona haku mele 'ana e pili ana i 92,3% o ka kalapona, ma ke ana wela kiʻekiʻe excrete nui dala o keia waiwai me ka paa. haawi aku i ka mea i 'ano huali malamalama. Ma keia hihia i ka'ā mahana hoʻoholo ole wale o ka'ōlinolino'ā, akā, kona waihoʻoluʻu. Ke kiekie Mahana O Ke Kai - ka oi aku onetime luminescence waihoʻoluʻu mea kalapona (particles). Ikeia oia kai mehana o, ua piha oia me ka acetylene hiki, e hoomalamalama mai ka hola umikumamalima manawa hou ma mua o ka wā, he pono ole kinoea kukui. O ia ka mea, i UAIAaIN e uila ho'ā, hoʻohana acetylene no ka ho'ā nā hoʻomau i ka paikikala ipukukui a me nā omnibuses.

E like me ka hooulu ana o ka hana, a pau pono nui dala o ia i huiʻia me acetylene. Kaniak ka mea, ma ka hanalima me ka unahiʻole, i lilo ai wale i loko o ka hope kenekulia. E like me ka hopena o ia ka "Ua Hopu", hoomaka ae la ka pilina i ke hoʻohana 'ia no ka hoʻohana' hana. No? Ieoaeunoai manao acetylene carbide loaa mai ma ka I hoopio ai hoi i ka wai. Kēia huahana ua ike no kona loa he nui kaʻawaʻawa loa ala ma muli o ka impurities hookomoia ma ka mea o ka ammonia a me ka hydrogen sulfide. I mea, o ka chemically maemae waiwai i ka weakly hai ethereal ala. Ua mea māmā ma mua o ke ea, ka hakakino kaumaha o ka acetylene ka 26,038. Kinoea mea colorless, Ua hooholo koke wailana i loko o na wai a pāʻoihana, ka solubility hoʻoholo ma ke ana wela o ka pāʻoihana.

O kēia loea i no ka loaa acetylene mai methane ma elektrokrekinga - he kaʻina hana ma i ka'ūholo uila ua mua i hala methane kinoea ma ka wela,ʻaʻole ma lalo o 1600 ° C. A laila, e pale aku decomposition o acetylene kinoea ua malalo i kokololio ka huʻihuʻiʻana. Kēia iaoia mea mana i loko o ia kekahi hapa o ka wela i loaa mai ma ke'ā o ka waiwai hiki ke kuhikuhi i paio hahana maoli nō i ka kekahi naoh kalapona, hoʻolako ka hoʻomauʻana o ka papa.

Acetylene ua hoʻomano hoʻohana ma ka kuʻihao, aʻoki i eliiaʻi, e loaa i ka loa olinolino keokeo malamalama, no ka? Iecaianoaaiiie o pahū mea.
