Acid Ethanoic. meatotino faaletino, sauniuniga ma le faaaogaina

acid Ethanoic (o le isi igoa - acid acetic) - o se mea faatulagaina o se matua faavae vaivai acid carboxylic. O le pogai o lenei acid ua valaauina acetates. E ala i lenei mea e mafai ona maua ester methyl acid ethanoic: ethanal = + ethanoic ester methyl acid.
acid ethanoic meatotino Faaletino

1. ethanoic acid (fua faatatau - CH3COOH) o se suavai e aunoa ma lanu ma manogi ma se tofo oona lelei.
2. hygroscopic. Matua soluble i le vai.
3. ethanoic acid miscible ma sili ona solvents. E lelei soluble kasa ma tuufaatasi inorganic e pei Talofa (iodide hydrogen), HF (fluoride hydrogen), HBr (bromide hydrogen), HCl (acid hydrochloric) ma le tele o isi.
4. E pei linear ma dimers cyclic.
5. O le faifai pea dielectric o 6.1.
6. sulu vevela i luga o le ea E 454 tikeri.
7. ituaiga acid ethanoic azeotropes ma tetrachloride carbon, benzene, cyclohexane, toluene, heptane, ethylbenzene, trichlorethylene, o-xylene, p-xylene ma bromoforom.

e mafai ona maua acid Ethanoic i le tele o auala:

1. O le oxidizing acetaldehyde ma le okesene i le ea. O lenei faagasologa e mafai na i luma o se vaega taua - acetate manganese i se vevela mai i le 50 i le 60 tikeri. O le tali e faapea:

2CH3CHO (acetaldehyde) + O2 (okesene) = 2CH3COOH (acid ethanoic)

2. O le auala oxidative faaaogaina alamanuia. Muamua mo oxidation acid ethanoic o butane sa faaaogaina ma acetaldehyde.

Atsetilaldegid oxidized na i luma o le manganese acetate i maualuga i uunaiga ma le vevela. O le fua o le acid ethanoic tusa ivasefulu-lima pasene.

2CH3CHO + O2 = 2CH3COOH

na oxidized N-butane i se vevela o le 150 i le 200 tikeri. A gaoioi loa lenei acetate cobalt se auala.

2C4H10 + 5O2 = 4CH3COOH + 2H2O

Ae ona o le tulai mai taua i le tau o le suauu, na avea ai le aoga o nei auala uma e lua ma sa le pine ae suia i le faagasologa o le sili atu le lelei mo le carbonylation o methanol.

3. O le carbonylation catalytic o methanol - o se auala taua mo le acid ethanoic tuufaatasia. E tupu faaupuga tuutuuga:

CH3OH + CO = CH3COOH

4. E i ai auala e tuuina biochemical foi e faaaoga ai le tomai o microorganisms e oxidize ethanol. E taʻua lenei faagasologa fermentation acetic. A faaaogaina o se ester mata mea aqueous lenei ava malosi ethyl po etanolosoderzhaschie suavai (sua fefete). O lenei eseese laasaga faagasologa lavelave. E mafai ona faamatalaina e le faamatalaga lenei:
CH3CH2OH (ava malosi Eteru) + O2 (okesene) = CH3COOH (acid ethanoic) + H2O
talosaga

- ethanoic acid fofo aqueous faaaoga i le gaosiga o meaai, o le kuka ma le faasaoina;

- ethanoic acid o loo faaaogaina e foafoa odoriferous vailaau ma fualaau faasaina (acetone, acetyl);

- faaaogaina i le dyeing ma lomitusi;

- e avea o se tali auala mo le oxidation o nisi mea faatulagaina (hydrogen peroxide oxidation o sulfides);

- talu taitoalua acid ethanoic maua se manogi ogaoga lē lelei, e mafai ona faaaogaina nai lo le amonia.
