Acetic acid, vai e leai se lanu, e malosi lona manogi manogi.O le mea liusuavai o le acetic acid o le 16.6 ℃, o le mea faʻafefe o le 117.9 ℃, o le maualuga o le vaʻaia o le 1.0492 (20/4 ℃), ma le faʻailoga faʻasolosolo o le 1.3716.O le acetic acid mama e mafai ona fausia ai se malo e pei o le aisa i lalo ifo o le 16.6 °C, o lea e masani ona ta'ua o le acetic acid.O le acetic acid o se vailaʻau faʻasolosolo taua, e masani ona faʻaaogaina e saunia ai le vinyl acetate monomer (VAM), cellulose acetate, acetic anhydride, terephthalic acid, chloroacetic acid, polyvinyl alcohol, acetate ma metal acetate.
Acetic acid o loʻo faʻaaogaina lautele i le faʻaogaina o meaola masani, vailaʻau, vailaau faʻasaina, lolomi ma vali, ie, meaʻai, vali, faʻapipiʻi ma le tele o isi pisinisi.Acetic acid ose vaila'au mata'utia taua.O tekinolosi gaosiga fa'apisinisi o le acetic acid e masani lava ona aofia ai: metotia carbonylation methanol, fa'ama'iina o le acetaldehyde, fa'ama'iina sa'o o le ethylene ma le fa'ama'iina o le suau'u mama.Faatasi ai ma i latou, o le methanol carbonylation o le tekinolosi sili ona faʻaaogaina, e sili atu ma le 60% o le aofaʻi o le gaosiga o le lalolagi atoa, ma o loʻo faʻaauau pea lenei tulaga.
O le malosi o le gaosiga o le acetic acid o le lalolagi o loʻo faʻaalia ai se tulaga maualuga, ma o lona manaʻoga i le lalolagi atoa o le a faʻatupulaia foi i se fua faatatau faaletausaga e tusa ma le 5% i nai tausaga o lumanaʻi, lea o le 94% o le gaosiga o le acetic acid fou o le lalolagi o le a tupu i totonu. Asia, ma le itulagi Asia o le ai ai foi i le lumanai.Taʻitaʻia le televave o le faʻatupulaia o manaʻoga maketi i totonu o le lima tausaga.
talosaga:
1. Acetic acid derivatives: e masani ona faʻaaogaina i le faʻaogaina o le acetic anhydride, acetate, terephthalic acid, vinyl acetate / polyvinyl alcohol, cellulose acetate, ketene, chloroacetic acid, haloacetic acid, ma isi;
2. Vailaau: Acetic acid o loʻo faʻaaogaina e avea o se solvent ma vailaʻau mataʻutia, e masani ona faʻaaogaina i le gaosiga o le penicillin G potassium, penicillin G sodium, procaine penicillin, antipyretic tablets, sulfadiazine, sulfamethoxazole, norfloxacin, ciprofloxacin Floxacin, acetylsalicylic acid. prednisone, caffeine, ma isi;
3. Vaitafe eseese: acetate, sodium diacetate, acid peracetic, ma isi;
4. Pigments ma ie lomitusi ma vali: e masani ona faʻaaogaina mo le gaosiga o faʻamaʻi faʻasalalau ma vali vat, faʻapea foʻi ma le lomitusi ie ma le gaosia o le vali;
5. Ammonia faʻapipiʻi: i le tulaga o le cupric acetate ammonia vai, e faʻaaogaina e pei o le faʻamamaina o le kasa faʻapipiʻi e aveese ai sina vaega itiiti o le CO ma le CO2 o loʻo i ai;
6. I le ata: formulation as developer;
7. I le tulaga o le pa'u fa'anatura: fa'aaogaina e fai ma fa'a'au'au;
8. I totonu o fale faufale: e faʻaaogaina e fai ma anticoagulant.
