Acetic acid

Incazelo emfushane:

Kuyinto ye-monic monic monic, isakhi esiyinhloko sikaviniga. I-Pure Anhydrous acetic acid (i-glacial acetic acid) uketshezi olungenamibala we-hygroscopic, ikhambi lawo lamanzi abuthakathaka acidic futhi liwonakaliso, futhi lililimaze kakhulu izinsimbi.

Ukwakheka kwe-crystal ye-acetic acid kukhombisa ukuthi ama-molecule ahlanganiswe ngama-dimers (abizwa nangokuthi ama-dimers) ngama-hydrogen bond, futhi kukhombisa ukuthi ama-carbor acid anesisindo se-hydrogen kanye ne-acetic acid enesisindo se-forers esimweni esiqinile, esinguketshezi noma ngisho ne-gaseous state ngendlela yama-molecular Ukuzimisela kwesisindo ngokuncishiswa kwamaphoyinti weqhwa kanye ne-X-RAY. Lapho i-acetic acid ichithwa ngamanzi, izibopho ze-hydrogen phakathi kwama-dimers ziphule ngokushesha. Amanye ama-carboxylic acid akhombisa ukumiswa okufanayo.

Ukusetshenziswa Komkhiqizo

Ukusetshenziswa Kwezimboni

1. I-acetic acid ngumkhiqizo wamakhemikhali obuningi, kungenye yama-organi acidi abaluleke kakhulu. Isetshenziselwa ikakhulukazi ukukhiqizwa kwe-acetic anhydride, acetate kanye ne-cellulose acetate. I-Polyvinyl Acetate ingenziwa ngamafilimu kanye nama-adhesives, futhi futhi iyinto eluhlaza ye-vinyon yokwenziwa ye-vinylon. I-Cellulose Acetate isetshenziselwa ukwenza i-Rayon ne-Motion Photo Film.

2. I-acetic ester eyakhiwe ngotshwala obuphansi yi-solvent enhle kakhulu, esetshenziswa kabanzi embonini yepende. Ngoba i-acetic acid inciphisa izinto eziphilayo eziningi, ivame ukusetshenziswa njenge-solvent ye-organic (isib. Nge-oxidation ye-P-XYLENE ukukhiqiza i-terephthalic acid).

I-3. I-acetic acid ingasetshenziswa kwezinye izixazululo zokukhanyisa kanye nokupholisha, kusisombululo esibi se-acidic njenge-buffer (esebenza nge-nickel plating ye-operlel, esikhaleni se-ninc, ku-adtivation clickel plating se-electolitive, futhi kuvame ukuthuthukisa amandla okugeza acijile.

4. Ngokukhiqizwa kwe-acetate, efana ne-manganese, i-sodium, ukuhola, i-aluminium, i-zinc, i-cobalt kanye nezinye izithasiselo zensimbi, ukudaya kwendwangu kanye nezithasiselo zezimboni zesikhumba; I-Lead Acetate ingupende umbala wokuhola mhlophe; I-TetraAcetate ye-Lead Syntheisis iyi-realent ye-organic (ngokwesibonelo, ukuhola i-tetraacetate kungasetshenziswa njenge-ejenti eqinile ye-oxidizing, kunikeze umthombo we-acetoxy futhi ulungiselele amakhompiyutha okuhola ezi-organic, njll.).

I-5. I-acetic acid nayo ingahle isetshenziswe njenge-reagent yokuhlaziya, ukuhlanganiswa kwe-organic, upement kanye nokuhlanganiswa kwezidakamizwa.

Ukusetshenziswa kokudla

Embonini yokudla, i-acetic acid isetshenziswa njenge-acidifier, i-accuring e-ejenti kanye nephunga lapho enza uviniga owenziwe, i-acetic acid ixutshwe ku-4-5% ngamanzi, futhi kufakwa ama-ejenti ahlukahlukene we-flavoging. Ukunambitheka kuyafana nokwamaviniga wotshwala, futhi isikhathi sokukhiqiza sifushane kanti intengo ishibhile. Njengomenzeli omuncu, ungasetshenziselwa ukuthosa okuhlanganisiwe, ukulungiswa kweviniga, okusekonisiwe, jelly kanye ushizi, ngokuya ngezidingo zokukhiqiza zokusetshenziswa okufanele. Kungaphinde kwaqamba isithuthukisi sephunga sewayini lempepho, inani lokusetshenziswa lingu-0.1 ~ 0.3 g / kg.
