Hloekilengglacial acetic acid, ke hore, anhydrous acetic acid, acetic acid ke e 'ngoe ea li-organic acid tsa bohlokoa, metsoako ea manyolo. E tiisa leqhoa ka mocheso o tlase 'me hangata e bitsoaglacial acetic acid. Sebaka sa leqhoa ke 16.6° C (62° F), 'me ka mor'a ho tiisa, e fetoha kristale e se nang mebala. Mokelikeli oa eona oa metsi o na le asiti e fokolang ebile e senya haholo, 'me e senya ka matla litšepe. Mouoane o na le phello e khopisang mahlong le nkong. Kahoo, lisebelisoa tse khethehileng ke life glacial acetic acidliindastering tse fapaneng?
Taba ea pele, tšebeliso ea liindasteri tsa glacial acetic acid
1. E sebelisetsoa lidae le li-inks tsa maiketsetso.
2. Ka indasteri ea lijo, e sebelisoa e le acidity regulator, acidifier, pickling agent, flavor enhancer, spice joalo-joalo. Hape ke sethethefatsi se setle sa antimicrobial, haholo-holo ka lebaka la bokhoni ba eona ba ho fokotsa pH e ka tlase ho pH e hlokahalang bakeng sa kholo e nepahetseng ea likokoana-hloko.
3. E sebelisoa indastering ea rabara le polasetiki. E sebelisoa e le mokelikeli le thepa ea ho qala bakeng sa li-polymers tse ngata tsa bohlokoa (tse kang PVA, PET, joalo-joalo) indastering ea rabara le polasetiki.
4. E sebelisoa e le thepa ea ho qala bakeng sa pente le metsoako ea sekhomaretsi.
5. Glacial acetic acid e boetse e phetha karolo ea bohlokoa haholo ho hlatsoetsa liaparo, haholo-holo ho thibela tahlehelo ea 'mala oa liaparo, e na le ho tlosoa ka matla ha matheba,' me e ka fokotsa pH, kahooglacial acetic acid e tumme haholo ka ho hlatsoetsa liaparo. Ha e sebelisoa, e lokela ho sebelisoa ho latela litaelo tse itseng, 'me e ke ke ea e sebelisa ka bofofuglacial acetic acid.
Ea bobeli,glacial acetic acid tshebediso ya dikhemikhale
1. Bakeng sa motsoako oa cellulose acetate. Cellulose acetate e sebelisoa filiming ea lifoto le masela. Pele ho qaptjoa filimi ea cellulose acetate, filimi ea lifoto e ne e sebelisoa ho tloha ho nitrate 'me ho ne ho e-na le mathata a mangata a tšireletso.
2. E sebelisoa e le solvent bakeng sa motsoako oa terephthalic acid. P-xylene e na le oxidized ho terephthalic acid. Asiti ea terephthalic e sebelisoa ha ho etsoa PET mme e sebelisoa haholo ha ho etsoa libotlolo tsa polasetiki.
3. E sebelisoa haholo ho kopanya li-ester ka ho sebetsana le lino tse tahang tse fapaneng. Li-derivatives tsa acetate li sebelisoa haholo e le li-additives tsa lijo.
4. E sebelisetsoa ho qaptjoa ha vinyl acetate monomer. Joale monoma e ka etsoa polymerized ho etsa poly (vinyl acetate), eo hape e tsejoang ka hore ke PVA.
5. E sebelisoa e le solvent mefuteng e mengata ea organic catalytic reactions.
6. E sebelisoa e le sekala le ho tlosa mafome. Nengasiti ea acetice arabela ka metsi, sekala sa hisses le li-bubble lia nyamela, li e pshatla ho tloha ho tiileng ho ea mokelikeli o ka tlosoang habonolo.
