Acetic acid (CAS 64-19-7), yog ib qho tseem ceeb organic acid siv nyob rau hauv cov tshuaj, tshuaj, zaub mov, thiab kuaj industries. Ib qho ntawm nws lub cev tseem ceeb tshaj plaws yog nws cov solubility zoo heev hauv dej, uas cuam tshuam ncaj qha rau nws li cas khaws cia, thauj, tsim, thiab siv rau hauv cov txheej txheem kev lag luam.
Puas yog cov tshuaj acetic acid (GAA) yaj hauv dej?
Acetic acid (CH₃COOH)pom zoo solubility hauv dej, ua kom miscible nrog dej hauv txhua qhov kev faib ua feem. Cov cuab yeej no yog los ntawm pawg carboxyl (-COOH) hauv nws cov qauv molecular, uas muaj qhov muaj zog polarity thiab hydrogen bonding peev xwm. Thaum Acetic Acid (GAA) yaj hauv dej, nws pawg carboxyl cuam tshuam nrog dej molecules ntawm hydrogen bonds. Ib txhij, qee cov acetic acid molecules ionize rau hauv acetate ions (CH₃COO⁻) thiab hydrogen ions (H⁺), imparting ib tug tsis muaj zog acidic xwm rau cov tshuaj (pH kwv yees li 2.4 ntawm ib tug concentration ntawm 1 mol / L).

Kev siv acetic acid (GAA CAS 64-19-7)
Lub siab solubility ntawm Acetic Acid (GAA CAS 64-19-7) Kev daws ua kom nws cov ntawv thov dav hauv kev lag luam khoom noj (raws li tus neeg sawv cev souring), cov tshuaj synthesis (xws li, cellulose acetate ntau lawm), thiab cov chaw soj nstuam (rau kev npaj tsis haum).
Glacial Acetic Acid (GAA) yog acetic acid nrog ib qho concentration Ntau dua lossis sib npaug li 99%, lub npe rau nws qhov qis - kub solidification rau hauv dej khov - zoo li cov muaju. Nws cov ntawv thov poob rau hauv plaub pawg loj:
Cov ntawv thov kev lag luam
Synthesis ntawm vinyl acetate (siv nyob rau hauv cov xim thiab adhesive manufacturing), terephthalic acid (raws li raw khoom rau PET plastics), thiab lwm yam. Kwv yees li 60% ntawm lub ntiaj teb no glacial acetic acid yog siv nyob rau hauv tshuaj ntau lawm.
Raws li pH adjuster hauv textile dyeing kom ntseeg tau tias cov xim tsis zoo adsorption.
Cov chaw kuaj mob
Acetic Acid (GAA CAS 64-19-7) tov yog siv los npaj buffers (xws li, acetic acid-sodium acetate buffer, pH 4.0-5.5) rau kev sim biochemical.
Ib qho 3% -5% dilution feem ntau yog ua haujlwm rau cov kua dej nag.
Cov ntawv thov kho mob
Kev kho cov kab mob cog qoob loo: Siv 80% + concentration ncaj qha mus rau lub wart rau cauterization. Kev tswj hwm yuav tsum tau ua kom tsis txhob muaj kev kub nyhiab ntawm daim tawv nqaij.
Disinfecting otitis externa: Dilute mus rau 2% -3% siv rau inhibiting fungi thiab kab mob.
Khoom noj khoom haus additives
Khoom noj khoom haus- qib acetic acid (GAA CAS 64-19-7) tov (E260) yog siv rau hauv pickling thiab seasonings, nrog rau kev nyab xeeb txwv ntawm 10g / kg.
Kev khaws cia thiab kev thauj mus los ntawm Acetic Acid (GAA CAS 64-19-7)
- Cia: GAA yuav tsum muab khaws cia rau hauv cov thawv ntim rau hauv qhov chaw txias, qhuav, zoo - qhov cua qhov chaw, deb ntawm qhov chaw ntawm hluav taws xob thiab oxidizing agents.
- Kev Thauj Mus Los: Ua raws li cov cai tswj kev thauj mus los tsis zoo los tiv thaiv kev xau thiab kev puas tsuaj.
