E like me ka acetylene i hoomakaukauia mai methane

Acetylene mea he waiwai pili ana i ka papa o alkynes. Ma nā hua'ōlelo, ka hydrocarbon i loaʻa i loko o kēlā lātoma Triple hoopaa. Ma keia Nine Inch haʻilula acetylene like penei: C ₂ H _2. I iho, keia waiwai mea he colorless kinoea, i mea nui māmā ma mua o ka ea. Acetylene loaa mai methane. Ka waiwai mea kū'ē, a pahū.

Pehea e loaa acetylene

O methane i loko o ka hale e kiʻi i ka acetylene ka loa paʻakikī. Ke easiest papa hana no ka hoʻokaʻawale o ke kinoea - reacts keia wai me ka kalipuna carbide. He nui no oe paha hoomanao pehea e kiola i loko o puddles apana o ka waiwai a me ka mea i ka naoh ia lŘlŘ. A uaʻike i ka kokololio e hoinoia. Like no ka kalipuna carbide, laila ia i nā maule iho la, ho okumu i ka nui loa o ka hua. A like naoh hiki ke palapalaia e like me:

CaC ₂ + 2H ₂ O = C ₂ H + ₂ Ca (OH) _2.

He nui oaoieei-kalipuna carbide ua hoʻohana 'ia, a iloko ona i kakauia he nui nui o impurities. E like me ka hopena, i ka naoh nā me ka wai ke hookuu aku oia ino ala. Ua kupu mai ke kahua, pu me ka nīnūnē nui o acetylene kinoeaʻawahia ohu. Loa pinepine ia mea he phosphine, hydrogen sulfide, a no laila, ma luna o. Kēia papa hana o ka loa, he pono ole, e like me ka loaa acetylene mai methane mea hiki i kūikawā lako a pan wale.

hoÿomäkaukau hana

Pehea e kiʻi i ka acetylene mai methane ma ka hanalima 'ia? Currently hoʻohana 'ia hoʻokahi wale iaoia - ńlua. I ka makaukau ana o acetylene ua lawe decoupling -C-C. Kēia ia lŘlŘ ma ke alo o catalysts, a ma kekahi i lawa ke kiekie ana wela waiū. No ka hoʻohana methane - maoli kinoea. Kēia mea he inexpensive a me ka hana i loaʻa maka mea. Ia mea no kēia mea, i kaʻuʻina o ka loa kupono iaoia nā hoʻokele waiwai a technically.

Pehea ua Hi ohia

E lawe mai i ka huli ana o ka "methane - acetylene" i loko o kekahi mau aoao. Ma ka hihia mua, ma kona ano maoli kinoea ua hala ma o ka mālama '-wela'ūholo uila. Ka wela ke hiki mai i ka 1600 ° C. Ma hope o paio hahana maoli nō, kokololio anuanu maila 'ia lŘlŘ. Ka lua o ka papa hana ua ma muli o ka hana o ka wela i ua ua loaʻa ma ka hapa'ā o ka acetylene.

Naoh helu kaulike i palapala ia penei - "acetylene methane":

1. Ina au: 2CH ₄ = C ₂ H ₂ + 3H _2.

1. I Ina II: 6SN ₄ + 4O ₂ = C ₂ H ₂ + 8H + 3SO ₂ + CO ₂ + 3H ₂ O.

Poe akamai i mai e waiho aku i ka hana no ka papaa o acetylene nā paukūʻolokaʻa aʻe o ka nohona kiwikā o ke keleawe. No, i loko o ka haku mele 'ana o ka oka a pau i loaʻa ke keleawe. Mai acetylene chemicallyʻeleu, ka mea hiki ke pane koke me ka mea hiki ke hooheheeia. E like me ka hopena o keia palapala pahū paʻakai.

Ka hoʻohana o acetylene

Acetylene - he waiwai i ua hoʻomano hoʻohana i nā hanalima nāʻoihana. Loa pinepine, ua hoʻohana 'ia kēia kinoea i loko o ka? Iecaianoaaiiie o'eto ka waiʻona like me ka papa kuhikuhi maka mea. Eia hou, i ka acetylene ua hoʻohana 'ia no kekahi mau' ano o ka laholio, Ka lula ea Ke a me aceticʻakika.

ʻeleu kinoea ua hoʻomano hoʻohana ', a i kuʻihao, aʻoki i ka wā i kekahi mau mea hiki ke hooheheeia. It E e hoʻomaopopo i ka lapalapa ikaika ua hana i loko o ka'okesaside ma o oxygen acetylene. Kinoea kahi mea i lawa huali malamalama i na kukui o ka hana nona iho type. Ma muli acetylene hua pahū, i mea hou i hoʻohana like detonators.
