【Phapang】

Sebaka se qhibilihang sa acetic acid e phahameng-hloekileng ke likhato tse 16.7, kahoo asiti ea acetic e tla etsa leqhoa ka mor'a hore mocheso o fokotsehe, 'me o bitsoa glacial acetic acid. Acetic acid ke lebitso le akaretsang, e ka ba bohloeki bo phahameng, hape e ka ba bohloeki bo tlase. Glacial acetic acid le acetic acid ke ntho e ts'oanang, e nang le monko o matla o hlabang, phapang ke feela hore na e tiile, asiti ea acetic hangata e mokelikeli mocheso oa kamore ea 20 ° C, 'me ka kakaretso e tiile mocheso o tlase oa 16 °. C, eo hape e bitsoang glacial acetic acid.

Glacial acetic acid (pure matter), ke hore, anhydrous acetic acid, acetic acid ke e 'ngoe ea li-organic acid tsa bohlokoa, metsoako ea manyolo. E thatafala ho ba leqhoa mochesong o tlase 'me hangata e tsejoa e le glacial acetic acid. Ho atolosoa ha molumo nakong ea ho tiisa ho ka etsa hore setshelo se phatlohe. Sebaka sa khanya ke 39 ℃, moeli oa ho phatloha ke 4.0% ~ 16.0%, 'me mahloriso a amohelehang moeeng ha a fete 25mg / m3. Asiti e hloekileng ea acetic e tla hoama ka har'a likristale tse kang leqhoa ka tlase ho sebaka se qhibilihang, kahoo asiti ea anhydrous acetic e boetse e bitsoa glacial acetic acid.

Ho feta moo, asiti ea acetic ke eona ea khale ka ho fetesisa e sebelisoang haholo China. Acetic acid (36% -38%), glacial acetic acid (98%), formula ea lik'hemik'hale CH3COOH, ke organic monic acid, karolo e ka sehloohong ea asene.

【Ts'ebetso】

Acetic acid e ka lokisoa ka motsoako oa maiketsetso le ho belisoa ha baktheria. Biosynthesis, tšebeliso ea ho belisoa ha baktheria, ke karolo ea 10% feela ea tlhahiso eohle ea lefats'e, empa e ntse e le mokhoa oa bohlokoa ka ho fetisisa oa ho hlahisa acetic acid, haholo-holo asene, hobane melao ea linaha tse ngata e hloka hore asene e be lijong e tlameha ho lokisoa ke mekhoa ea baeloji, le belisoa e arotsoe ka belisoa aerobic le anaerobic belisoa.

(1) Mokhoa oa ho belisoa ha aerobic
Boteng ba oksijene e lekaneng, libaktheria tsa Acetobacter li ka hlahisa acetic acid ho tsoa lijong tse nang le joala. Hangata cider kapa veine e tsoakiloeng le lijo-thollo, 'mela, raese kapa litapole lia siloa ebe lia belisoa. Lintho tsena li ka belisoa hore e be asiti ea acetic boteng ba enzyme ea catalytic tlasa oksijene.

(2) mokhoa oa ho belisoa ha anaerobic
Libaktheria tse ling tsa anaerobic, ho kenyelletsa le litho tse ling tsa mofuta oa Clostridium, li khona ho fetola tsoekere ka ho toba ho acetic acid ntle le tlhokahalo ea ethanol e le bohareng. Sucrose e ka lomosoa hore e be acetic acid ha oksijene e le sieo.
Ho phaella moo, libaktheria tse ngata li khona ho hlahisa asiti ea acetic ho tsoa metsoakong e nang le k’habone e le ’ngoe feela, e kang methanol, carbon monoxide, kapa motsoako oa carbon dioxide le hydrogen.
