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:

1.DELWE KULULA KWE-DYSES NEZIMALI.

2. Isetshenziswa ekuhlanganiseni kwamakha.

3. Isetshenziswa embonini yenjoloba nepulasitiki. Isetshenziswa njenge-solvent kanye nokuqala impahla yama-polymers amaningi abalulekile (njenge-PVA, isilwane, njll.) Embonini enjoloba.

4. Isetshenziswa njengento yokuqala yezinto zokupenda nezinamathela

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

I-Acetic Acid - Ukuphepha

I-Oral LD50 yamagundane: 3530mg / kg; I-Percutaneous LDSO yonogwaja: 1060mg / kg; inhalation thlc50 yamagundane: 13791mg / m3. iyakhuthaza. Ukuphefumula kwalo mkhiqizo umdwebi kuyacasula ekhaleni, umphimbo kanye nepheshana lokuphefumula. Ukucasula kakhulu ngamehlo. Ukuvikelwa, hlambulula ngamanzi agelezayo. Kuvinjelwe ngokuphelele ukuxubana ne-oxidizer, i-alkali, amakhemikhali adliwayo, njll. Gcina endaweni yokugcina izinto epholile, evutha umoya. Gwema kude nomlilo nemithombo yokushisa. Gcina isitsha esivaliwe. Gcina ngokuhlukile ku-oxidizers ne-alkalis.
