Pureglacial acetic acid, kureva, anhydrous acetic acid, acetic acid ndeimwe yeakakosha organic acids, organic compounds. Inoomesa muchando pakudzika kwakadzika uye inowanzonziglacial acetic acid. Nzvimbo yechando ndeye 16.6° C (62° F), uye mushure mekusimba, inova kristaro isina ruvara. Mushonga wayo une aqueous hauna kusimba asidhi uye unoodza zvakanyanya, uye unoparadza zvakanyanya kumasimbi. Mupfunga une mhedzisiro inoshatirisa pameso nemhino. Saka, ndezvipi zvinoshandiswa zvakananga glacial acetic acidmumaindasitiri akasiyana?
Kutanga, glacial acetic acid kushandiswa kwemaindasitiri
1. Inoshandiswa kugadzira dhayi neingi.
2. Muchikafu chekudya, inoshandiswa se acidity regulator, acidifier, pickling agent, flavour enhancer, spice nezvimwe zvakadaro. Iyo zvakare yakanaka antimicrobial agent, kunyanya nekuda kwekugona kwayo kuderedza pH iri pasi pepH inodiwa kuti hutachiona huwedzere kukura.
3. Inoshandiswa muindasitiri yerabha nemapurasitiki. Inoshandiswa sechinhu chinonyungudutsa uye kutanga zvinhu kune akawanda akakosha mapolima (akadai sePVA, PET, nezvimwewo) muindasitiri yerabha nemapurasitiki.
4. Inoshandiswa sechinhu chekutanga chepende uye zvinonamatira zvinhu.
5. Glacial acetic acid inoitawo basa rakakosha mukuwacha, kunyanya mukudzivirira kurasikirwa kweruvara pahembe, ine kubviswa kwakasimba kwemavara, uye inogona kumisa pH, sakaglacial acetic acid inonyanya kufarirwa mukuwacha. Paunenge uchishandisa, inoda kushandiswa maererano nemimwe mirairo, uye haigone kushandisa nebofuglacial acetic acid.
Chepiri,glacial acetic acid kushandiswa kwemakemikari
1. Nokuda kwekugadzirwa kwe cellulose acetate. Cellulose acetate inoshandiswa mumifananidzo firimu uye machira. Pamberi pekugadzirwa kweselulosi acetate firimu, firimu remifananidzo raimbogadzirwa kubva kunitrate uye pakanga paine zvakawanda zvekuchengetedza.
2. Inoshandiswa sechinhu chinogadziriswa chekugadzirisa terephthalic acid. P-xylene inonzi oxidized to terephthalic acid. Terephthalic acid inoshandiswa mukugadzirwa kwePET uye inoshandiswa zvakanyanya mukugadzira mabhodhoro epurasitiki.
3. Inoshandiswa zvakanyanya kugadzira esters nekuita nemadoro akasiyana. Acetate derivatives inoshandiswa zvakanyanya sezvokudya zvinowedzera.
4. Inoshandiswa pakugadzirwa kwevinyl acetate monomer. Iyo monomer inogona kubva yave polymerized kuita poly (vinyl acetate), inozivikanwawo sePVA.
5. Inoshandiswa se solvent mune zvakawanda organic catalytic reactions.
6. Inoshandiswa seyero uye inobvisa ngura. Riniacetic acidinopindirana nemvura, chiyero chinoridza mhere uye mabubbles anonyangarika, achiiputsa kubva pakasimba kuita mvura inogona kubviswa nyore nyore.
