Chemical Properties:

Acetic acid, CH3COOH, imvura isina ruvara, inovhuvhuta pane tembiricha yepakati.Mushonga wakachena, glacial acetic acid, une zita rawo nekuda kweaizi-yakafanana nekristaro kutaridzika pa15.6°C.Sezvinopihwa kazhinji, acetic acid ine 6 N aqueous solution (inenge 36%) kana 1 N mhinduro (inenge 6%).Izvi kana kuti zvimwe zvinwiwa zvinoshandiswa mukuwedzera zviyero zvakakodzera zveacetic acid kune zvekudya.Acetic asidhi ndiyo inoratidzika asidhi yevhiniga, iyo yakasarudzika kubva pa3.5 kusvika 5.6%.Acetic acid uye acetates zviripo mumiti yakawanda uye mhuka dzemhuka mune zviduku asi zvinoonekwa.Iwo akajairwa metabolic intermediates, anogadzirwa nemhando dzebhakitiriya dzakadai seAcetobacter uye anogona kugadzirwa zvachose kubva kucarbon dioxide nema microorganisms akadai seClostridium thermoaceticum.Iyo gonzo inoumba acetate pachiyero che1% yehuremu hwemuviri wayo pazuva.

Semvura isina ruvara ine kunhuhwirira kwakasimba, kunorwadza, kunhuhwirira kwevhiniga, inobatsira mubhotela, cheese, mazambiringa uye michero inonaka.Yakanyanya kudiki yakachena acetic acid seyakadaro inoshandiswa muzvikafu, kunyangwe ichiiswa muchikamu neFDA sechinhu cheGRAS.Nekuda kweizvozvo, inogona kushandiswa mune zvigadzirwa zvisina kufukidzwa neDefinitions uye Standards of Identity.Acetic acid ndiyo chikamu chikuru chevhiniga uye pyroligneous acid.Muchimiro chevhiniga, anopfuura mamirioni makumi maviri nenomwe lb akawedzerwa kuchikafu muna 1986, aine huwandu hwakaenzana hunoshandiswa se acidulants uye flavouring agents.Muchokwadi, acetic acid (sevhiniga) yaive imwe yepakutanga kunhuhwirira vamiririri.Mavhiniga anoshandiswa zvakanyanya mukugadzira saladhi yekupfeka uye mayonnaise, magaka anovava uye anotapira uye akawanda masosi uye katsi.Anoshandiswawo mukurapa nyama uye mumagaba emamwe muriwo.Mukugadzira mayonnaise, kuwedzerwa kwechikamu cheacetic acid (vhiniga) kune munyu- kana shuga-yolk inoderedza kupisa kweSalmonella.Mvura inosunga zvinyorwa zvemasoseji kazhinji inosanganisira acetic acid kana munyu wesodium, nepo calcium acetate inoshandiswa kuchengetedza kuumbwa kwemiriwo yakakangwa, yemumagaba.

Application:
Kushandiswa kweacetic acid muindasitiri

1. Inoshandiswa mukugadzirwa kwedhayi neingi.

2. Inoshandiswa mukugadzirwa kwezvinonhuwira.

3. Inoshandiswa mumaindasitiri erabha uye epurasitiki.Inoshandiswa sechinhu chinonyungudutsa uye kutanga zvinhu kune akawanda akakosha mapolymer mumaindasitiri erabha nemapurasitiki (akadai sePVA, PET, nezvimwewo).

4. Inoshandiswa sechinhu chekutanga chepende uye zvikamu zvekunamatira

5. Inoshandiswa muindasitiri yekugadzira chikafu sechinhu chinowedzera mucheki uye sosi uye sechikafu chekuchengetedza.

Kushandiswa kweacetic acid mumakemikari synthesis

1.Inoshandiswa mukugadzirwa kwe cellulose acetate.Cellulose acetate inoshandiswa mumafirimu emifananidzo uye machira.Pamberi pekugadzirwa kweselulosi acetate firimu, firimu remifananidzo raishandiswa kugadzirwa nenitrate, iyo yaive nematambudziko akawanda ekuchengetedza.

2. Inoshandiswa sechinhu chinogadziriswa chekugadzirisa terephthalic acid.Paraxylene inonzi oxidized to terephthalic acid.Terephthalic acid inoshandiswa kugadzira PET, iyo inoshandiswa zvakanyanya kugadzira mabhodhoro epurasitiki.

3. Inoshandiswa zvakanyanya mukuita nemadoro akasiyana siyana kugadzira esters.Acetate derivatives inoshandiswa zvakanyanya sezvokudya zvinowedzera.

4. Inoshandiswa mukugadzirwa kwevinyl acetate monomer.Iyo monomer inogona kubva yave polymerized kuita poly (vinyl acetate) inowanzozivikanwa sePVA.pVA ine huwandu hwakawanda hwekushandisa kubva kumushonga (nekuda kwekuenderana kwayo kune nanotechnology (sekudzikamisa) kusvika pakugadzira mapepa).

5. Inoshandiswa sechinhu chinonyungudutsa mune dzakawanda organocatalytic reactions.

Kushandiswa kweacetic acid mukurapa

1. Acetic acid inoshandiswa mune imwe nzira inonzi pigmented endoscopy, iyo inoshandiswa kune yakajairwa endoscopy.

2. Acetic acid inoshandiswa pakuongorora kwekuona kwekenza yechibereko uye maronda.Inoshandiswa zvakare pakuongorora gomarara rechibereko.

3. Acetic acid inoshandiswa kurapa otitis kunze.

4. Acetic acid dzimwe nguva inoshandiswa kurapa zvirwere zvebhakitiriya uye fungal.

5. Mukuongorora kwema laboratory pamakonzo, acetic acid yakaratidzwa kuderedza mhinduro yekuputika mumakonzo.

Kushandiswa kwemumba kweacetic acid

1. Acetic acid ndiyo chikamu chikuru chevhiniga.

2. Vhiniga inoshandiswa kunhonga miriwo

3. Inoshandiswa pakugadzira saladhi

4. Inoshandiswa mukubika kubika.Inopindirana nesoda yekubikisa kuburitsa kabhoni dhaikisaidhi gasi kuita kuti chikafu chiite fluffy.
