Kaniak benzene

Aia i kekahi mau aoao o ka hanalima, a keʻena hoʻokolohua? Iecaianoaaiiie o benzene, i lauwili i kulike ai me ka mea i ka huina hoonui e koho i kekahi wahi ho mea. Hawaii Nine Inch? Iecaianoaaiiuo like ia increasingly pili likeʻole onaona i huiʻia, e like me Coke umu kinoea hua mai la i ka coking o ka lanahu. Ka mea, e kaiāulu hoʻohana 'ia a me nā lānahu ahi hohono hapa i hanaʻia i distillation o ka maka aila.

Coking lanahu - ka nui kaʻina anu u ma ka kila hana, ka mea, he pono ke loaa Coke. Aia mea i pono, e wehewehe i au mamuli o ka enehana a pau, a ua muli i ka makaukau o ka benzene, lawa ia i ka olelo ia ma keia hihia ka mea, ua hanaʻia i loko o kaʻanuʻu, ka wā o ka lānahu ahi ua decomposed a me ka decomposition nā huahana i Coke, a volatiles kuhikuhi - Coke umu kinoea. I kona mahu ka lanahu hohono. A pau keia kinoea hele ma ka condenser nenoaiu, aia no he kaawale ana o ka waiwai aha ia. Ma hope o elektrofiltrovaniya Coke umu kinoea mua iloko ona i kakauia i ka paʻa o ke aloha i huiʻia me benzene. Ua makaukau e hōʻoiaʻiʻo kona benzene hua ma ka maka palapala kaha like kokekau i 10-11 kg no tonne o maloo lanahu.

Lanahu hohono no hoi e leie aku e loaa benzene. Technologyʻaneʻi mea reminiscent o ke ala i ka i me ka mākaʻi e loaa benzene mai Coke umu kinoea. Ka mea mea, i loko wale lanahu hohono - heʻano luna 'ma ka haku mele' ana ke keʻena läÿau, heʻano o onaona ke aloha i huiʻia. No hoi, a hiki i keia la, uaʻaʻole maopopo maopopo i ka haku mele 'ana o ka hui, a pela i hoʻokumu i ke ola ana o ka oi ma mua o 500 (!) Eiiiiiaiou. Aaioee enehana mea he kaʻina hana o ka elua-ke kahua kaawale kēpau i loko o kekahi mau mahele. No keia mea kela mea keia mea o lakou, ua hoolilo i ka hana o ka alkalis e weheʻakika hapa. Ke kūpono puaʻa hiwa i hana - anthracene a me ka naphthalene, e like me ka malamalama, a ua komo i loko o ka haku mele 'ana a me ka benzene.

Ka hana e halii mai i loaa benzene ma ka maka palapala, i ka ai-kapaia maka benzene. E loaa maemae hui, pono e ua holoiʻia maka benzene mai ka luaipele i huiʻia. Ma kēia kaʻina hoomaopopo mau kahua o ka hoʻonaʻauao. Ka mua ia lŘlŘ pono ana o ka luaipele impurities, a me ka lua o ka kaawale ukuhiia huikala ma distillation. Kekahi o nā huahana o keia kaawale ana, e e benzene.

Ka nui kahi o ka likeʻole aromatics kaʻaila kā. I mea no ke aha la ke kālā no? Iecaianoaaiiuo benzenesʻeleu ma ia huahana.

Benzene Ua kaʻawale kekahi mai acetylene. Kēia mea ma lalo o maʻamau rula mea he kinoea, ia mea colorless, kokoke insoluble i loko o ka wai, mea māmā ma mua o ka ea. Mawaena o ka Nine Inch waiwai o ke kinoea mai ka hiki e polymerize, a no ia mea hoʻohana ma ka hana no ka hana benzene mai acetylene. Kēia papa hana i oi i olelo mua iaʻi, mai ka oiai ua ike mai o e pili ana a me ka malama ana i rula no ka Nine Inch naoh. Ka nui, e hoike i acetylene, i iho, He loa pahū, no ka mea, ka hoʻohana 'ana i ka hana komo ai i ka pono, e hooko me ka ikaikaʻanoʻenehana ka hoʻopaʻi, a kūikawā pono, o ka oi aku wela-hoʻopale. I ka Ia manawa, ma mua o ka loaa acetylene mai benzene, e hoʻokō lawa ana wela i ka 400 C, a hoopaa ia ma ke alo o ka graphite. Kēia hana i manaoia ma 1866 ma Farani chemist M. Berthelot, nae, o ka waiwai a hua ua'āina haʻahaʻa. No laila, ma ka 'ike loea i keia la i ka Ua laha ana o nāʻano likeʻole o nā catalysts, a no ka accelerating ka naoh a me ka mahuahua o ka hua o ka maemae benzene.

Ma lalo o keʻena hoʻokolohua kumu, benzene ua IeAUPIIe, IAa IO i loaa, aka, ina nae e pono aicieeaao, ka alloying iaoia ma ka benzoicʻakika me ka mekala 'åkilikai. I ka hopena o keia naoh ka benzene.
