Ulungiselela acetic acid

Acetic acid - uketshezi esobala kungekho nto enemibala emihle elinendawo iphunga isici, futhi ukunambitheka omuncu. It okungukuthi kalula miscible ngamanzi i angenamkhawulo lemali, hygroscopic. Mhlawumbe ukuxubana kumakhemikhali awuketshezi eziningi. Ngo iningi acetic acid futhi kalula encibilikayo compounds wezinto ezingaphili futhi amagesi.

Uviniga ikhiqizwa ikakhulu inqubo iwayini ukuvutshelwa. Kubonakala kanjalo endulo, izithelo uviniga, buhlanjululwe ngamanzi, ngokuthi iwayini elimuncu. Kukholakala ukuthi inomphumela zokwelapha ku amathumbu, ephumula sohudo. Ngakho-ke, amasosha ayephethwe u bephoqeleka ukuba uhlale isikhathi eside ezimweni ezinzima, njalo waba naye igabha lewayini nge acid alulaze.

Namuhla, abantu abaningi bakhetha ukufinyelela zokupheka of imithi yendabuko. Futhi apple cider uviniga ukuze eziningi kubonakala panacea for ukukhuluphala. Futhi, unyawo okugeza akhulule ukukhathala.

Nokho, uviniga kuthenga ngeke njalo elishiwoyo kwilebula. Futhi ukukhiqizwa acetic acid by ukuvutshelwa apula amanzi ushukela ingxube - akunzima, ngisho nasekhaya.

AmaRoma asendulo uzilungiselele isiphuzo akhethekile anuka oludakayo, ngokuthi ubisi. Ukuze uthole lokhu iwayini isibilile e phambili amabhodwe, okuholela kumiswa acetate phambili - ". Ushukela lomthofu 'wesimo amnandi kakhulu ukuthi" Izinga likashukela Saturn "wabizwa ngokuthi futhi noma aristocrats Abaningi ngubani idliwe lesi siphuzo, ethola ezingamahlalakhona phambili ubuthi.

Futhi isicelo sokuqala esiwusizo sokuba nezinto eziqondile acetic acid safinyelela kithi imibhalo - irekhodi usosayensi ngesiGreki Teofasta ezihlobene abaningi ku-BC 3 leminyaka. Bona amchaza ngokuthi uviniga nomthelela izinsimbi, kanjalo esikhiqiza zombala asetshenziswe art. Ngosizo uviniga etholwe phambili esimhlophe nethusi-Xph.

Phakathi Renaissance ukukhiqizwa kwe acetic acid esekelwe Sublimation kwezinye acetates metal, isibonelo, lapho ziphuzo zazihluzwa ezomile zethusi acetate (II). Le ndlela is kabanzi embonini cishe ukuba phakathi nekhulu leminyaka eledlule.

A 8 leminyaka wavula Alchemist Arabhu Jabr bin Haiyan ukulungiswa bagxila acetic acid Uketshezi ngu ziphuzo zazihluzwa, nje njengoba etholakale phisa.

Adolf Kolbe German, umthaki wemithi, ngo-1847 sekuvule ukukhiqizwa acetic acid esuka inorganics. Le ndlela uncika chlorination carbon disulfide ukuba carbon tetrachloride, okuyinto ke wabe pyrohydrolysis ukuze tetrachlorethylene. Isinyathelo esilandelayo kule nqubo okungukuthi i-chlorination ka tetrachlorethylene ukuze trichloroacetic acid. Ngokulandelayo, ngokungithinta electrolytic ukunciphisa ejenti ngqo iguqulwe ukuze acetic acid.

Kusukela ngasekupheleni kwekhulu le-19 nasekuqaleni kuka-20 ukukhiqizwa kwe acetic acid esekelwe ziphuzo zazihluzwa kwezinkuni. Ngokuyinhloko uviniga akhiqizwa eJalimane. Cishe ingxenye yesithathu yomphakathi wabantu uviniga ekhiqizwa ushiye ukukhiqizwa indigo - udayi ezimbonini.

Acetic acid, ukulungiswa okuyinto esekelwe ziphuzo zazihluzwa of sawdust, ukubunjwa yayo chemical uhlukile etholwe ezinye izindlela. Kodwa izindleko le ndlela kuzuzisa kakhulu, futhi ngakho-ke Wawugujelwani ukukhiqizwa yezimboni of uviniga - bagxila acetic acid.

acetic acid usawoti ziye zasetshenziswa embonini. Ngokwesibonelo, ukuhlukanisa yensimbi kanye ne-aluminium okuphuma kulawa amanye amaqembu 3 of izinsimbi ngu chemical analysis besebenzisa ukuphendula abilayo acetic usawoti acid emanzini.

On zethusi acetate, indigo futhi "White Lead", ukusetshenziswa for Umdwebo, okukhulunywe ngaye ngenhla. Isilinganiso acetic usawoti acid lomthofu, lowo owayephatha kwakheka isiphuzo ezinesihlungu ngokuthi "Sapa", etholakala ngokoqobo wesimanje, ukusetshenziswa kwabo imithi. Ithusi usawoti acetic acid lihambisana zethusi myshyakovistokisloy libizwa oluhlaza Paris (shveynfurtskoy) futhi sisetshenziswa kabanzi ku ukulawula isitshalo izinambuzane.
