Asiti Sulfuric. Mekhoa ea ho lokisetsa. kopo

asiti Sulfuric e se e ho pharaletseng sebelisoa ka masimo a sa tšoaneng tsa mesebetsi ea batho. Morao-rao tsa lik'hemik'hale indasteri e kenyeletsa yona ho ya ka lethathamo la tlhahiso e khōlō, boemo ba ho lokolloa lona ke pontshi sa tobang ea ba tlhahiso ea naheng e lik'hemik'hale. Selemo le selemo lefatše hlahisa ka bang limilione tse 160 tsa boima ba lithane ntho ena.

Ho latela physico-lik'hemik'hale bona thepa, acid e le sulfuric ke acid e dicarboxylic, sena motsoako oa sebabole fihla phahameng ka ho fetisisa ho kena moea boemo (6). Tlas'a maemo a tloaelehileng, ho ikakhela ka setotsoana sulfuric acid e boemo ba emela e boima mafura mokelikeli ba se nang 'mala, kapa monko. asiti Sulfuric e sebelisoa ka tharollo. Ka solvent ka sebelisoa e le metsi a tloaelehileng, le trioxide sebabole. Ho e nkoa e le e tharollo ea metsi, haeba karo-karolelano ea palo ea limolek'hule tsa trioxide sebabole ho palo ya metsi e ka tlase ho be le bonngoe. Ka holimo sena index ea ho hlahisa maikutlo e sebediswa - sebabole trioxide tharollo ka acid e sulfuric kapa oleum.

Sulfuric acid e fana ka tlhahiso e fana ka ena bohlokoa pōpo ea sehlahisoa menontsha thulaganyou e matsoai, e sebelisoa e le electrolyte ka libeteri etella pele-acid e, acid e ea ke karolo e khōlō ea ba lokisetsa ho ea matsoai a sa tšoaneng matsoai le acid. Lik'hemik'hale likhoele, lidae, mosi-fehla motlakase le liqhomane ka thekenoloji lona difeme e acid e sulfuric. Ntle ho ke ke ha khoneha ho nahana oli, tšepe, Textile, letlalo le a mang liindasteri.

Esita le indasteri ea lijo e sa ntle le ho sebelisa ntho e - ho fumana lijo tseloe E513 (emulsifier). Industrial Organic go tswakana, dehydration (tshepetso fumana esters, diethyl phenylate), hydration (tlhahiso ea ethanol tloha ethylene) sulfonation (tlhahiso ea la detergents le intermediates bakeng sa ba lokisetsa ho ea lidae), alkylation (tswakana isooctane, caprolactam, nhua polyethylene glycol), hlaphoheloa halogenated filter bakeng sa mela distilled tlhahiso ea metsi - le ea mong oa dithulaganyo tsena e na le tšebeliso ea acid e sulfuric.

Tlhahiso ea asiti sulfuric fana ka motheo mosebedisi ho fetisisa tsa ntho - manyolo tswakana. Ka mohlala, ho hlahisa thane e le ea menontsha phosphate ke ho hlokahala hore ho qeta ho tloha tse pedi ho tonnes tse tharo le halofo tsa acid e sulfuric. Ka lebaka lena, sulfuric acid e likhoebo tšepetsoe tlhahiso ea asiti sulfuric, hammoho le thepa ea mohaho lifektheri hlahisa manyolo.

mekhoa e 'meli e lokisa li sebelisoa bakeng sa tlhahiso ea asiti sulfuric. Sulfuric acid e fana ka tlhahiso e ka sehloohong ho ikopanya le mokhoa le e etsang liphesente tse mashome a robong, nitrous (Tower) mokhoa o tlase ata. Ho sa tsotellehe mefokolo le ho e mong le e kereke, tlhahiso ea asiti sulfuric tloha pyrites nitrous mahae ka theko tshebetso motle ho feta, bohloeki, 'me mahloriso a phahameng a qeta sehlahiswa ka sehokelo sa.

Tsebe e ka ikopanya le sulfuric acid e dimela tswakana mokhoa, ho sulfuric acid e fana ka tlhahiso o lumella arotsoe ka mekhahlelo e meraro. Ka ho ba sethaleng pele, roasting pyrite, bakeng sa morero oo ontong ho baka ka seo ho thoeng ke "fluidized bethe". Mokhahlelo oa bobeli e akarelletsa ho kena moea oa dioxide e sebabole ho oxide e sebabole (VI), 'me ka ho ba sethaleng boraro ke lokisetsa ho ea oleum, tseo li lahleloa ka ditanka me a romeletsa ho bareki.

asiti sulfuric tlhahiso ea nitrous mokhoa o ha le a fumanwa tšebeliso lohle ka lebaka la lekaneng ho hloka sekoli khumo sehlahisoa, kahoo fokotsa tšebeliso ea eona.

Ho sa tsotellehe hore mekhoa le mekhoa bakeng sa ba lokisetsa ho ea, tlhahiso ea asiti sulfuric hloka bahlahisi ho lefa eketsehile ka makhetlo a lebisa tlhokomelo ho sireletsa tikoloho.
