Amioga fa'aletino:
1. Suavai e le lanu ma le ita ita.
2. Liu liusuavai 16.6 ℃; vevela 117.9 ℃; Itu ole moli: 39 ℃.
3. Suavai solubility, ethanol, benzene ma ethyl eter immiscible, e le mafai ona solu i le carbon disulphide.
Teuina:
1. Teu i totonu o se faleteuoloa malulu, fa'aalili.
2. Taumamao mai le afi, vevela. O le vaitau malulu e tatau ona faʻamaualuga le vevela e sili atu i le 16 DEG C, e puipuia ai le faʻamalosi. I le vaitau malulu, e tatau ona tausia le vevela i luga atu o le 16 DEG C ina ia puipuia / aloese mai le faʻamalosi.
3. Ia fa'amaufa'ailoga le koneteina. E tatau ona vavae ese mai le oxidant ma le alkali. E tatau ona aloese mai le faʻafefiloi i soo se auala.
4. Fa'aaogā moli e fa'asa'o pa'u, mea e fa'alelei ai le ea.
5. Mea fa'ainisinia ma mea faigaluega e fa'asa ai le fa'aogaina o aloiafi faigofie.
6. O nofoaga e teu ai e tatau ona faʻapipiʻiina mea faʻapitoa mo togafitiga faʻafuaseʻi ma mea faʻaoga talafeagai.
Fa'aaogā:
1. Derivative: Fa'aaoga masani i le synthetising acetic anhydride, acetic ether, PTA, VAC / PVA, CA, ethenone, chloroacetic acid, ma isi.
2.Pharmaceutical: Acetic acid e pei ole solvent ma pharmaceuticalraw material, e masani ona faʻaaogaina mo le gaosiga o le penicilin G potas-sium, penicilin G sodium, penicillin procaine, acetanilide, sulfadiazine, ma le sulfamethoxazole isoxazole, norfloxacin, ciprofloxacin, acetyl pnishenalic acid. ,kafeina, ma isi.
3. Intermediate: acetate, sodium hydrogen di, acid peracetic, ma isi
4.Destuff ma lomitusi ie ma vali: Fa'asili ona fa'aaogaina i le gaosia o vali fa'asalalau ma vai vai, ma lomitusi ie ma le fa'againa o le vali.
5. Synthesis ammonia: I le tulaga o le cuprammonia acetate, faʻaaogaina i le faʻamamaina o syngas e aveese ai se litl CO ma CO2
6. Ata: Fausiaina
7. Pa'u fa'anatura: Coagulant
8. Alamanuia faufale: Puipuia le sima mai le fa'aaisa9. I le addtin faʻaaoga lautele i le vai togafitiga, syntheticfiber, vailaau faʻalaʻauʻala, palasitika, paʻu, vali, gaosiga uʻamea ma alamanuia rubber.
Acetic acid, e taʻua foi o le acetic acid (36% -38%), glacial acetic acid (98%), vailaʻau vailaʻau CH3COOH, o se vailaʻau monic organic, o le vaega autu o le vineka. O le mama anhydrous acetic acid (glacial acetic acid) o se mea e leai se lanu hygroscopic solid ma le malulu o le 16.6 ° C (62 ° F) ma avea ma tioata e leai se lanu pe a maeʻa le faʻamalosi. O lona vaifofo vai e vaivai le suka ma erosive, ma o le ausa e faʻafefe ai mata ma isu.
Glacial acetic acid (mea mama), ie anhydrous acetic acid, organic compound. E fa'amausali i le aisa i le maualalo o le vevela ma e masani ona ta'ua o le glacial acetic acid. O le fa'alauteleina o le voluma a'o fa'amalosi e ono mafua ai ona malepe le atigipusa. O le moli moli o le 39 ℃, o le faʻalavelave faʻalavelave e 4.0% ~ 16.0%, ma le maualuga faʻatagaina faʻatonuga i le ea e le sili atu i le 25mg / m3. O le acetic acid mama o le a malolo i tioata e pei o le aisa i lalo ifo o le mea e liusuavai ai, o lea e taua ai le acetic acid anhydrous acid glacial acetic acid.
E mafai ona vaʻaia e le tutusa le lua, o le moli o le aisa acetic acid o le 39 ℃, o le faʻalavelave faʻalavelave o le 4.0% ~ 16.0%, ma le maualuga o le faʻatagaina i le ea e le sili atu i le 25mg / m3, lea e iai. i oloa matautia, ma le acetic acid e le o ni oloa matautia.
