Unyuluglacial acetic acid, oko kukuthi, i-anhydrous acetic acid, i-acetic acid yenye yezinto ezibalulekileyo eziphilayo, i-organic compounds. Iqina ibe ngumkhenkce kumaqondo obushushu aphantsi kwaye idla ngokubizwa ngokubaglacial acetic acid. Indawo yomkhenkce yi-16.6° C (62° F), kwaye emva kokuqina, iba yikristale engenambala. Isinyibiliko saso esinamanzi sibuthathaka kwaye sinoburharha obugqithisileyo, kwaye sinokonakalisa kakhulu isinyithi. Umphunga unefuthe elicaphukisayo emehlweni nasempumlweni. Ke, zeziphi iindlela ezikhethekileyo zokusetyenziswa glacial acetic acidkumashishini ahlukeneyo?
Okokuqala, ukusetyenziswa kwe-acetic acid kwimizi-mveliso
1. Isetyenziselwa iidayi zokwenziwa kunye neenki.
2. Kwishishini lokutya, isetyenziswa njenge-acidity regulator, i-acidifier, i-agent ye-pickling, i-flavour enhancer, i-spice njalo njalo. Ikwayi-agent elungileyo ye-antimicrobial, ikakhulu ngenxa yokukwazi ukunciphisa i-pH engaphantsi kwe-pH efunekayo ekukhuleni kwe-microbial ngokugqibeleleyo.
3. Isetyenziswa kwishishini lerabha kunye neeplastiki. Isetyenziswe njenge-solvent kunye nesiqalo sezinto ezininzi ezibalulekileyo (ezifana ne-PVA, i-PET, njl.) kwi-rubber kunye ne-plastiki imboni.
4. Isetyenziswe njengento yokuqala yepeyinti kunye nezithako zokunamathela.
5. Glacial acetic acid ikwadlala indima ebaluleke kakhulu ekuhlambeni impahla, ikakhulu ekuthinteleni ukulahleka kombala empahleni, inokususwa okuqinileyo kwamabala, kwaye inokunciphisa i-pH,glacial acetic acid ithandwa kakhulu kwindawo yokuhlamba impahla. Xa usebenzisa, kufuneka isetyenziswe ngokwemiyalelo ethile, kwaye ayikwazi ngokumfamekileyo ukusebenzisaglacial acetic acid.
Isibini,glacial acetic acid ukusetyenziswa kweekhemikhali
1. Ukwenziwa kwe-cellulose acetate. I-Cellulose acetate isetyenziswa kwifilimu yezithombe kunye neendwangu. Ngaphambi kokuveliswa kwefilimu ye-cellulose acetate, ifilimu yezithombe yayisetyenziselwa ukwenziwa kwi-nitrate kwaye kwakukho iinkxalabo ezininzi zokhuseleko.
2. Isetyenziswe njenge-solvent ye-synthesis ye-terephthalic acid. I-P-xylene i-oxidized kwi-terephthalic acid. I-Terephthalic acid isetyenziswa ekudibaneni kwe-PET kwaye isetyenziswa kakhulu ekwenzeni iibhotile zeplastiki.
3. Isetyenziswa ngokubanzi ukwenza ii-esters ngokusabela ngee-alcohols ezahlukeneyo. I-acetate derivatives isetyenziswa ngokubanzi njengezongezo zokutya.
4. Isetyenziselwa ukuhlanganiswa kwe-vinyl acetate monomer. I-monomer emva koko ingenziwa i-polymerized ukwenza i-poly (vinyl acetate), eyaziwa ngokuba yi-PVA.
5. Isetyenziswa njengenyibilikisi kwiimpendulo ezininzi ze-organic catalytic.
6. Isetyenziswe njengesikali kunye ne-rust remover. Niniiacetic acidiphendulana namanzi, isikali i-hisses namaqamza ayanyamalala, isaphule isiqina sibe lulwelo olunokususwa ngokulula.
