Ka hoʻohana o'etolina. 'etolina mall

'etolina o ka simplest o ke aloha i huiʻia i kapa like alkenes. Kēia colorless combustible kinoea, me he mea alaʻaiʻana a me ka oluolu. Natural kumu nā maoli kinoea a me kaʻaila, ia mea no hoi he kūlohelohe hōmona ma ka mea kanu, kahi e inhibits ka ulu a me ka paipai 'ana i ke oo ana o ka hua. Ka hoʻohanaʻana i'etolina mea, he pono ole i ka hanalima ke aloha kemika. Ua Ua ua hanaʻia ma ka paio hahana maoli nō maoli kinoea, he mahele heheʻe i ka wahi o 169,4 ° C, nā kapuahi wahi - 103 9 ° C.

'etolina: mall hiʻona a me ka waiwai

Hydrocarbons i nā lātoma i loaʻa ka hydrogen a me ka kalapona. Ka mea, oko a nui ma ka olelo o ka helu ana i hookahi, a mau mea paa a me ka mall kohoʻia o kēlā me kēia ke keʻena. Kekahi o ka simplest, akā, biologically a me ka hoʻokele waiwai mea eʻoi aʻe hydrocarbon mea'etolina. Ua hele mai i loko o ka gaseous palapala, ia mea colorless a me ka mahalo flammable. Ua he a mau papalua palapala hoopaa kalapona nā'ātoma me ka hydrogen nā'ātoma. Ke Nine Inch haʻilula ka C ₂ H _4. Ke mall ano o ka lātoma ka laina no a hiki i ke alo o ka papalua hoopaa i loko o ka waena.
'etolina mea ono musky ala, aʻo ka mea oluolu, e kuhikuhi i ka waiwai i loko o ka lewa. Ua pili i ka ke kinoea i loko o ke gula palapala: i nalo honi ka wā i hui pūʻia me nā Nine Inch.

Noaia'etolina noi

'etolina ua hoʻohana 'ia i loko o nā kumu o nā waeʻano: ka lātoma mai a nui kalapona na kaula i kūkulu, a me ka maka mea no nā mau-kalapona i huiʻia. Polymerization - hou keia hoʻohuiʻia i ka ai iiiaanoaa o'etolina liʻiliʻi nā lātoma i loko o nui. Kēia kaʻina ia lŘlŘ ma kiʻekiʻe ka puʻuwai a me ka mahana. Noi i lehulehu'etolina. Polyethylene - he pīlali, a ua hoʻohana 'oi loa i loko o ka nui? Iecaianoaaiiie o ka'ōpala Film, uea ka paleʻana, a me ka ea hue. Kekahi ano o ka'etolina like lātoma pili ana i ke kahua o ka laina α-olefins. 'etolina o ka hoʻomaka mea no ka makaukau o ka helu ana o elua-kalapona i huiʻia e like me ethanol (hanalima waiʻona),'etolina'okesaside (antifreeze, polyester olona, a me ka ho film) o ka acetaldehyde a me ka vinyl koloriside. Ma waho aʻeo ia mau hui,'etolina a me ka benzene ano ethylbenzene, a ua hoʻohana 'ia i loko o ka? Iecaianoaaiiie o Ka lula ea Ke a me kemikala laholio. I ka waiwai ma ka ninau o kekahi o ka simplest hydrocarbons. Eia naʻe,'etolina waiwai e ka mea hoʻokele waiwai a biologically nui.

kālepa ana

'etolina ka waiwai i ke kumu maikai, no ka nui nui kalepa o ke aloha (kalapona a me ka hydrogen i loaʻa ka)ʻia. Single'etolina nā lātoma i e hui pu, e paka polyethylene (a 'o ia hoʻi ka hailona no nā lātoma o'etolina). Polyethylene ua hoʻohana 'ia e Ka lula ea Ke. A eia hoi, e hiki ke hoʻohana 'ia no ka hana ana o detergents, a me kemikala lubricants, i nā Nine Inch mea i hoʻohana i ka ho'ēmi i kū'ē. Ka hoʻohanaʻana i'etolina no styrenes nui i loko o ke kukuluia'na o ka laholio a me aiiay'ōpala. Eia hou, ka mea, ua hoʻohana 'ia i loko o ke kāmaʻa hana, o ka oi aku haʻuki kāmaʻa, e like me ka pono me ia ma ka? Iecaianoaaiiie o ka ulia kaʻa papale hainaka. Ka hoʻohanaʻana i'etolina mea pāʻoihana nui, a me ke kinoea iho o kekahi o ka loa pinepine hua hydrocarbons puni ke ao.

Health P ÷ ino

'etolina mea he ola p ÷ ino i loko o ka wahi mua no ka mea, he nui flammable a me ka pahū. Ua hiki no hoi hana like me ka lāʻau ma haʻahaʻa nā hoʻohui like, ma o na la nausea, pōniuniu, headaches a me ka poho o ka ōhumu o ka neʻe 'ana. At kiekie nā hoʻohui like, ka mea hana e like me ka anesthetic, ma o na la unconsciousness, insensitivity i kaʻeha a me ka 'ē aʻe stimuli. A pau kēia mau hopena maikaʻi, ao ke ano e lilo ai i kumu no ka makeʻe oiaio hoi no ka poʻe i hana 'ana me ke kinoea. Ke dala o ka'etolina, me ka i loa kanaka i ke alo i loko o kā lākou mau kela la i keia ola ana, i IeAUPIIe, IAa IO kŘpa a uuku.

ka naoh o'etolina

1)'okesaside. Kēia hou o ka oxygen, e laʻa me, i loko o ka'okesaside o ka'etolina e'etolina'okesaside. Ua Ua hoʻohana 'ia i loko o ka? Iecaianoaaiiie o'etolina glycol (1,2-ethanediol), a ua hoʻohana' ia e like me he antifreeze, a ma ka hana ana o polyesters ma condensation polymerization.

2) Halogenation - naoh me'etolina fluorine, chlorine, bromine, iodine.

3) Ka chlorination o ka'etolina e lilo 1,2-dichloroethane, a me ka huli ana mahope o 1,2-dichloroethane i loko o ka vinyl koloriside lātoma. 1,2-dichloroethane mea he pono ke aloha'ūheheʻe, a me ka mea he waiwai precursor i loko o ka hoʻololi kemikala o vinyl koloriside.
4) Alkylation o - ohui hydrocarbons i ka waʻa hoopaa, no ka mea hoike, i ka hoʻololi kemikala o ethylbenzene mai'etolina a me ka benzene, ukali ma ka huli ana i ka styrene. Ethylbenzene He palapala no ka? Iecaianoaaiiie o styrene, kekahi o ka loa hoʻomano hoʻohana vinyl monomers. Styrene - lātoma hoʻohana no ka? Iecaianoaaiiie o polystyrene.

5) ke'ā o ka'etolina. Ke kinoea i loaa mai ma ka paio hahana maoli nō'eto ka waiʻona, a i kia sulfuricʻakika.

6) Hydration - ka naoh me ka hou ana o ka wai a hiki i ka waʻa hoopaa. Ka loa nui hanalima palapala noi o keia naoh o ka huli ana o ka'etolina i ka ethanol.

'etolina a me ka'ā

'etolina - He kinoea me ole 'ia nā pōpō, i mea poorly wailana i loko o ka wai. 'ā o'etolina i loko o ka lewa pu ma ke kahua o ke kalapona'okikene lua a me ka wai. Ma maemae palapala kinoea 'ā ho'ā maholahune lapalapa. I hui pūʻia me ka uuku nui o ka lewa, e 'oi aku ka lapalapa ahi, a he ekolu hookaawale papa - ka pahale kāna mau' ōlelo - ka unburned kinoea, uliuli-omaomao, ahu iho, a me ka mawahoʻohana, ai ka hapa 'ia' oxidized huina hoonui o ka mālama '-hui, ahu iho i ke ahi i loko o ka maholahune lapalapa. Ke resultant lapalapa hōʻike i ka luna 'moʻo o reactions, a ina ke kinoea läÿau, ua pākuʻi hou lewa maholahune, ahu iho i nā nalo.
