Umenzi Ixabiso Elihle leGlacial Acetic Acid CAS:64-19-7

Umenzi wexabiso elihle leGlacial Acetic Acid CAS: 64-19-7 Umfanekiso obonisiweyo

inkcazo emfutshane:

I-Acetic acid lulwelo olungenambala okanye ikristale enevumba elimuncu, elifana neviniga kwaye yenye yezona asidi ze-carboxylic zilula kwaye sisixhobo esisetyenziswa kakhulu kwikhemikhali. I-Acetic acid isetyenziswa ngokubanzi njengesixhobo sokulungisa iiseli, ekuveliseni i-cellulose acetate ikakhulu kwifilimu yefoto kunye ne-polyvinyl acetate kwiglu yomthi, iifayibha zokwenziwa, kunye nezinto zelaphu. I-Acetic acid ikwasetyenziswa kakhulu njengesixhobo sokunciphisa iiseli kunye nokulawula i-acidity kumashishini okutya.

Ukusetyenziswa kweGlacial Acetic Acid

1. I-acetic acid ifumaneka kwiviniga. Yenziwa kwi-distillation etshabalalisayo yomthi. Isetyenziswa kakhulu kwishishini leekhemikhali. Isetyenziswa ekwenziweni kwe-cellulose acetate, i-acetate rayon, kunye nee-acetate ezahlukeneyo kunye nee-acetyl compounds; njengesinyibilikisi seentsini, iioyile, kunye nee-resin; njengesigcini sokutya ekuprinteni nasekudayeni; nakwi-organic synthesis.
2. I-acetic acid yikhemikhali ebalulekileyo kwimizi-mveliso. Indlela esebenza ngayo i-acetic acid ene-hydroxyl equlethe iikhompawundi, ingakumbi ii-alcohols, iphumela ekwakhiweni kwee-acetate esters. Eyona ndlela isetyenziswa kakhulu yi-acetic acid kukuveliswa kwe-vinyl acetate. I-vinyl acetate inokuveliswa ngendlela esebenza ngayo i-acetylene kunye ne-acetic acid. Ikwaveliswa kwi-ethylene kunye ne-acetic acid. I-vinyl acetate yenziwa i-polymer ibe yi-polyvinyl acetate (PVA), esetyenziswa ekuvelisweni kweefayibha, iifilimu, izincamathelisi, kunye neepeyinti ze-latex.
I-cellulose acetate, esetyenziswa kwimpahla kunye nefilimu yefoto, iveliswa ngokuphendula i-cellulose kunye ne-acetic acid kunye ne-acetic anhydride xa kukho i-sulfuric acid. Ezinye ii-esters ze-acetic acid, ezifana ne-ethyl acetate kunye ne-propyl acetate, zisetyenziswa kwiindlela ezahlukeneyo zokusebenza.
I-acetic acid isetyenziselwa ukuvelisa iplastiki ye-polyethylene terephthalate (PET). I-acetic acid isetyenziselwa ukuvelisa amayeza.
3. I-Glacial Acetic Acid yi-acidulant elulwelo olucacileyo, olungenambala olunencasa ye-asidi xa luxutywe namanzi. Ingama-99.5% nangaphezulu ngobunyulu kwaye inyibilika kwi-17°c. Isetyenziswa kwiidiresi zesaladi ngendlela exutyiweyo ukubonelela nge-acetic acid efunekayo. Isetyenziswa njenge-preservative, acidulant, kunye ne-flavour agent. Ikwabizwa ngokuba yi-acetic acid, glacial.
4. I-acetic acid isetyenziswa njengeviniga yetafile, njengesigcini kunye nesixhobo esiphakathi kwishishini leekhemikhali, umz. iifayibha ze-acetate, ii-acetates, i-acetonitrile, amayeza, iziqholo, izinto zokuthambisa, iidayi (indigo) njl.njl. Iphepha leDatha yeMveliso.
5. Isetyenziswa kwi-aqueous and non-aqueous acid-base titrations.
6. Ukwenziwa kwee-acetate ezahlukeneyo, ii-acetyl compounds, i-cellulose acetate, i-acetate rayon, iiplastiki kunye nerabha ekutshiseni; njenge-laundry sour; i-printing calico kunye ne-dyeing silk; njenge-acidulant kunye ne-preservative ekutyeni; i-solvent yeentsini, ii-resins, ii-volatile oils kunye nezinye izinto ezininzi. Isetyenziswa kakhulu kwi-organic syntheses zorhwebo. Uncedo lwezonyango (i-acidifier).
