I-acetic acid, Ch3Cooh, iwuketshezi olungenamibala, olushintshashintshayo emazingeni okushisa akhona. I-Pure Compound, i-acelid ye-acerial acetic, ikweleta igama layo ekubukekeni kwe-crystalline enjengoku-15.6 ° C. Njengoba kuhlinzekwe ngokujwayelekile, i-acetic acid iyisisombululo esingamanzi ayisi-6 Lezi noma ezinye zezinkuthazo zisetshenziselwa ukwengeza amanani afanele we-acetic acid ekudleni. I-acetic acid yi-acid yesimo sikaviniga, okuhlushwa kwawo kusuka ku-3.5 kuye ku-5.6%. I-acetic acid ne-acetates ikhona ezitshalweni eziningi nasezicubu zezilwane ngamanani amancane kepha abonakalayo. Bangaphakathi kwe-metabolic i-metabolic, bakhiqizwa yilezi zinto ezinamagciwane njenge-acetobacter futhi zingahlelwa ngokuphelele kusuka ku-carbon dioxide ngama-microorganisms anjenge-cleppidium thermoacechims. I-rat yakha i-acetate ngesilinganiso esingu-1% wesisindo somzimba wayo ngosuku.

Njengoketshezi olungenamibala ngephunga elinamandla, elinomshini onamandla, onobuntu, luwusizo ku-bhotela, ushizi, amagilebhisi nezithelo. I-acid ecebile encane kakhulu ye-acetic esetshenziswayo njengoba isetshenziswa ekudleni, yize ihlukaniswa yi-FDA njenge-GDA. Ngenxa yalokho, ingaqashwa kwimikhiqizo engambozwa izincazelo namazinga wobunikazi. I-acetic acid iyingxenye eyinhloko kaviniga kanye ne-pyronoligned acid. Ngokwesimo seviniga, kufakwa ngaphezulu kwezigidi ezingama-27 Eqinisweni, i-actic acid (njengoba uviniga) yayingenye yama-ejenti wokunambitheka kwawo. Uviniga usetshenziswa kakhulu ekuhlelweni kokugqoka kwesaladi kanye nemayonnaise, ukhukhamba omuncu nomuncu nososo wamasoso amaningi nama-catsups. Baphinde basetshenziswe ekuphulukeni kwenyama nasekuthanjeni kwemifino ethile. Ekwenzeni imayonnaise, ukungezwa kwengxenye ye-acetic acid (uviniga) kusawoti- noma ushukela-yolk kunciphisa ukumelana nokushisa kwe-salmonella. Izingoma zokubopha amanzi zamasoseji zivame ukufaka i-acetic acid noma usawoti wazo we-sodium, ngenkathi i-calcium acetate isetshenziselwa ukugcina ukuthungwa kwezimpawu ezisikiwe, zemifino ekheniwe.

Isicelo:
Ukusetshenziswa kwe-acetic acid embonini

1. Kusetshenziswe ekuhlanganiseni kwamadayi kanye nama-inks.

2. Isetshenziswa ekuhlanganiseni kwamakha.

3. Isetshenziswa enjoloba yenjoloba kanye nepulasitiki. Isetshenziswa njenge-solvent kanye nokuqala kwezinto zama-polymers amaningi abalulekile kwinjoloba kanye nezimboni zepulasitiki (njengePVA, isilwane, njll.).

4. Isetshenziswa njengento yokuqala yezinto zokupenda nezinamathela

I-5. Isetshenziswa embonini yokusebenza kokudla njengezengezo kushizi nososo kanye nokugcina ukudla.

Ukusetshenziswa kwe-acetic acid ku-synthesis yamakhemikhali

1.Isuselwe ekuhlolweni kwe-cellulose acetate. I-Celsulose Acetate isetshenziswa kumafilimu nezindwangu. Ngaphambi kokusungulwa kwefilimu ye-cellulose acetate, ifilimu yezithombe esetshenziselwa ukwenziwa nge-nitrate, eyayinezinkinga eziningi zokuphepha.

2. Kusetshenziswe njenge-solvent yokuhlanganiswa kwe-terephthalic acid. I-ParaxLene i-oxidised to terephthalic acid. I-Teerephthalic acid isetshenziselwa ukuvumelanisa isilwane, esisetshenziswa kabanzi ukwenza amabhodlela epulasitiki.

I-3. Kusetshenziswe kabanzi ekuphenduleni ngokotshwala ahlukahlukene ukuhlanganisa ama-Esters. Ama-Derivatives we-Acetate asetshenziswa kabanzi njengezengezo zokudla.

4. Kusetshenziswe ekuhlolweni kwe-vinyl acetate monomer. I-monomer ingabe ise-polymerized ukuze kwakhiwe i-poly (vinyl acetate) nayo eyaziwa ngokuthi i-PVA. I-PVA inezinhlobonhlobo zezicelo ezivela kumuthi (ngenxa yokuthola ukuthambekela kwayo kwi-nanotechnology (njenge-spintizer) ekwenzeni amaphepha).

I-5. Isetshenziswe njenge-solvent ekuphendukeni okuningi kwe-orgacatalytic.

Ukusetshenziswa kwe-acetic acid kwezokwelapha

1. I-acetic acid isetshenziswa kwinqubo ebizwa nge-endoscopy ebekiwe, okuyinye indlela evamile ye-endoscopy.

2. I-acetic acid isetshenziselwa ukuhlola okubonakalayo komdlavuza wesibeletho kanye nezilonda. Iphinde isetshenziselwe ukuhlolwa komdlavuza wesibeletho.

3. I-acetic acid isetshenziselwa ukwelapha i-otitis externa.

I-4. I-acetic acid kwesinye isikhathi isetshenziselwa ukwelapha ukutheleleka kwamagciwane kanye nokukhunta.

5. Ekuhlolweni kwelebhu kumagundane, i-acetic acid ikhonjisiwe ukunciphisa impendulo yokuvuvukala egunjini.

Ukusetshenziswa kwasendlini kwe-acetic acid

1. I-acetic acid iyingxenye eyinhloko kaviniga.

2. Uviniga usetshenziselwa ukukha imifino

3. Isetshenziselwa ukugqoka isaladi

4. Isetshenziswa kwinqubo yokubhaka. Iphendula nge-baking soda ukukhipha i-carbon dioxide gesi ukwenza ukudla kufleffy.

5.Ukufakazelwa i-antifungal ejenti.
