Acetic acid

Kufotokozera mwachidule:

Ndi organic monic acid, chigawo chachikulu cha vinyo wosasa.Pure anhydrous acetic acid (glacial acetic acid) ndi madzi opanda mtundu a hygroscopic, njira yake yamadzimadzi imakhala yofooka komanso yowononga, ndipo imawononga kwambiri zitsulo.

Mapangidwe a kristalo a asidi acetic amasonyeza kuti mamolekyu amamangiriridwa ku dimers (omwe amadziwikanso kuti dimers) ndi ma hydrogen bond, ndipo ma dimers amapezekanso mumtundu wa nthunzi pa 120 ° C. Dimers ali ndi kukhazikika kwakukulu, ndipo zatsimikiziridwa kuti carboxylic zidulo ndi otsika maselo kulemera monga asidi formic ndi asidi asidi alipo mu mawonekedwe a dimers mu olimba, madzi kapena mpweya boma kudzera njira ya maselo kutsimikiza mtima ndi kuzizira mfundo kuchepetsa ndi X-ray diffraction.Acetic acid ikasungunuka ndi madzi, zomangira za haidrojeni pakati pa dimers zimasweka mwachangu.Ma carboxylic acid ena amawonetsa kuchepetsedwa kofananako.

Kugwiritsa Ntchito Mankhwala

Kugwiritsa ntchito mafakitale

1. asidi acetic ndi mankhwala ochuluka, ndi amodzi mwa ma organic acid ofunika kwambiri.Amagwiritsidwa ntchito kwambiri popanga acetic anhydride, acetate ndi cellulose acetate.Polyvinyl acetate ikhoza kupangidwa kukhala mafilimu ndi zomatira, komanso ndi zinthu zopangidwa ndi vinyl fiber.Cellulose acetate amagwiritsidwa ntchito kupanga rayon ndi filimu yoyenda.

2. acetic ester yopangidwa ndi ma alcohols otsika ndi yabwino kwambiri yosungunulira, yomwe imagwiritsidwa ntchito kwambiri pamakampani opanga utoto.Chifukwa asidi acetic amasungunula zinthu zambiri za organic, amagwiritsidwanso ntchito ngati zosungunulira organic (monga makutidwe ndi okosijeni wa p-xylene kupanga terephthalic acid).

3. asidi acetic angagwiritsidwe ntchito zina pickling ndi kupukuta njira, mu njira ofooka acidic monga chotchinga (monga kanasonkhezereka, electroless faifi tambala plating), mu theka-wowala faifi tambala plating electrolyte monga chowonjezera, mu njira passivation wa nthaka. , cadmium ikhoza kupititsa patsogolo mphamvu yomangira ya filimuyo, ndipo imagwiritsidwa ntchito kawirikawiri kusintha pH ya madzi osambira opanda acidic.

4. popanga acetate, monga manganese, sodium, lead, aluminiyamu, zinki, cobalt ndi mchere wina wachitsulo, womwe umagwiritsidwa ntchito kwambiri ngati chothandizira, utoto wa nsalu ndi zowonjezera zamakampani opanga zikopa;Lead acetate ndi utoto wa utoto woyera;Lead tetraacetate ndi organic synthesis reagent (mwachitsanzo, lead tetraacetate ingagwiritsidwe ntchito ngati oxidizing agent, kupereka gwero la acetoxy ndikukonzekera organic lead compounds, etc.).

5. asidi asidi Angagwiritsidwenso ntchito monga kusanthula reagent, organic synthesis, pigment ndi kaphatikizidwe mankhwala.

Kugwiritsa ntchito chakudya

M'makampani azakudya, asidi acetic amagwiritsidwa ntchito ngati acidifier, zokometsera ndi zonunkhira popanga viniga wosasa, asidi acetic amachepetsedwa mpaka 4-5% ndi madzi, ndikuwonjezera zokometsera zosiyanasiyana.Kukoma kumakhala kofanana ndi vinyo wosasa woledzeretsa, ndipo nthawi yopanga ndi yochepa ndipo mtengo wake ndi wotsika mtengo.Monga wowawasa wothandizira, angagwiritsidwe ntchito pawiri zokometsera, yokonza vinyo wosasa, zamzitini, odzola ndi tchizi, malinga ndi kupanga zofunika ntchito yoyenera.Ithanso kupanga chowonjezera chonunkhira cha vinyo wa zofukiza, kuchuluka kwa ntchito ndi 0.1 ~ 0.3 g/kg.
