Acetic acide masani ona taʻua o le ACOH, e faaigoa i le avea ma mea autu o le vineka, ma o se tasi o gaʻo sili ona taua. O le foliga o le saoloto i le natura e masani ona i ai i le tele o laau. Molecula CH3COOH. O le gaosia ma le faʻaaogaina o le vineka e iai se talaʻaga o le afe ma afe o tausaga. I Saina anamua, sa faamaumauina i le vineka. Ae o le acetic acid concentrated ose tusi kemisi manuia na atiae e Stahl i le 1700. O le acetic acid mama o se vai e leai se lanu ma e i ai sona tofo ita. O le mea liusuavai o le 16.6 ° C, o le vevela o le 117.9 ° C, ma le maualuga o le 1.049 (20/4 ° C). Solu i le vai, ethanol, glycerin, eter ma carbon chloride; e le mafai ona solu i le carbonide. O alisi vai e leai se vai e fa'aputu fa'atusa i le aisa, e masani ona ta'ua o le aisa acetic acid. A'a. E vaivai ma fa'aletino, acidicity o le acid, ma e mafai ona mafua ai le esterization tali i le ava malosi.
mea tau vaila'au:Acetic acid(AcOH) o se ga'o carboxylic e tasi-vaivai. O lo'o i ai uiga fa'apitoa o vaila'au carboxylic. E fegaioi ma nisi u'amea, u'amea u'amea ma hydroxides e maua ai masima. Ole tele ole acetic acids e iai fa'aoga taua. Acetate ferric acetate [Fe(C2H3OO)6OH(OOCCH3)2] ma le [Fe3(C2H3OO)6(OH)2(OOCCH3)] ma le acetate taʻitaʻi sa faʻaaogaina e pei o le mordant, ma faʻaaogaina le acetate ferrous mo le lolomiina. Acetic acid ma le ava malosi na esterified. E mafai fo'i ona fa'atino le fa'asao i le hydrocarbon unsaturated i lalo ole gaioiga ole catalyst. Alpha-hydrogen e mafai ona suia i halogens; Ma formaldehyde i lalo o le gaioiga o le catalyst, i totonu o le Chemicalbook laina o le ava aldehyde condensation; A fa'asalaina le nitric acid i le acetic acid, e mafai ona fa'aleleia atili le fa'asao. O le tali atu i le benzoyl chloride, acetyl chloride ma le benzoic acid e mafai ona fausia. Acetic acid e mafai ona faʻaaogaina e maua ai le tele o mea taua, e pei o le methyl acetate, ethyl ester, propyl ester, butyl ester, ma isi mea, o se solvent sili ona lelei i le faʻapipiʻiina ma le vali vali. Cellulose acetate, gaosia e ala i le fegalegaleaiga o le acetic anhydride ma cellulose, e mafai ona faʻaaogaina e fai ai ata tifaga, vali vali ma palasitika eseese. Carboxymethyl cellulose e mafai ona saunia e le chloroacetic acid. O le vinyl acetate o loʻo gaosia e le acetic acid ma le acetylene o se mea taua tele mo le tuʻufaʻatasia o vailaʻau, vali ma mea manogi, faʻapea foʻi ma se solvent taua mo togafitiga paʻu. O le acetic acid e iai sona sao taua i le gaosiga o fale gaosi oloa ma le faʻaogaina o meaola.
Talosaga fanua
Fa'aaogāga fa'apisinisi
1. Acetic acidose vaila'au tele ma o se tasi lea o vaila'au sili ona taua. E masani ona faʻaaogaina e gaosia ai le ethidine, ethyls ma le ethyl acetate. O le polyetate ethyl ester e mafai ona faia i se ata tifaga ma faʻapipiʻi, ma o se mea faʻapitoa foi mo fiber synthetic Velun. Ethyl acetic acid cellulose e mafai ona faia ai ata siliki ma ata tifaga.
2. O le ethyl acetate e faia e le ava maualalo-grade o se solvent sili ona lelei ma faʻaaogaina lautele i le fale vali. Talu ai ona o le tele o mea faʻaola e faʻamavaeina ai le acetic acid, o le acetic acid e masani ona faʻaaogaina solvents organic (mo se faʻataʻitaʻiga, mo le gaosiga o le phenyl acidic acidic acidic acid acid).
3. Acetic acid e mafai ona faaaogaina i nisi vaifofo pikiina ma polesi, e pei o se pa puipui (e pei o le galvanizing ma chemical nickel plating) i le vaifofo vai vaivai, faaopoopo additives i se electrolyte susulu nickel-plated hemuminal, ma le passivation o le zinc ma cadmium O le fofo e mafai ona faaleleia le malosi fusifusia o le ata o le passivation e masani ona faaaoga e faatonutonu ai le pH vaivai.
4. E faʻaaogaina e gaosia ai le masima uʻamea, e pei o le manganese, sodium, lead, alumini, zinc, cobalt ma isi metala, lea e faʻaaogaina lautele e fai ma faʻamalosi, vali ie ma paʻu paʻu alamanuia. Fouritic acid lead o se mea faʻapipiʻi synthetic reagent (e pei o le tetraitic acid lead e mafai ona faʻaaogaina e avea o se faʻamaʻi malosi, o se puna o le okesene acetyl, ma le saunia o mea faʻapipiʻi taʻavale, ma isi).
5. Acetic acid e mafai foi ona faʻaaogaina e fai ma suʻesuʻega suʻesuʻe, faʻasologa o meaola, pigmenti ma vailaʻau.
Fa'aaogāina o mea'ai
I totonu o pisinisi tau taumafa,acetic acide fa'aaogaina e fai ma sui fa'asa'o. A faʻaaogaina le manogi manogi ma mea manogi e fai ai le vineka gaosia, o le acetic acid e faʻafefeteina i le 4-5%, ma faʻaopoopoina meaʻai eseese. Taugofie. I le avea ai o se vailaʻau faʻamaʻi, e mafai ona faʻaaogaina mo faʻamaʻi faʻafefiloi. Ua saunia e faʻaaoga le vineka, apa, jeli ma sisi. E mafai fo'i ona e fatuina ni mea manogi e 0.1 ~ 0.3 g/kg.
Teuina ma felauaiga
Lapataiga mo le teuina: Teu i totonu o se faleteuoloa malulu ma ea. Taofi ese mai le afi ma le vevela. I le taumalulu, e tatau ona tausia le vevela o le teuina i luga aʻe o le 16 ℃ e puipuia ai le faʻamalosi. Ia fa'amaufa'ailogaina le koneteina. E tatau ona teu ese mai le oxidant ma le alkali, ma e le tatau ona faʻafefiloi. O lo'o fa'aaogaina moli e fa'asa'o fa'alavelave ma mea e fa'afefe ai. Aua le fa'aogaina masini masini ma mea faigaluega e fa'afefeteina. O le nofoaga e teu ai e tatau ona faʻapipiʻiina i masini faʻalavelave faʻafuaseʻi liki ma mea talafeagai e teu ai.
Puipuiga o felauaiga: O lenei oloa o le a lafoina e taavale tane alumini e saunia e pisinisi alumini i le taimi o felauaiga o nofoaafi, ma e tatau ona lipotia le faamaoniga a matagaluega talafeagai aʻo leʻi lafoina. O felauaiga o nofoaafi e le o tuʻuina e tatau ona faʻataunuʻuina e tusa ai ma le lisi o mea e teu ai oloa mataʻutia i totonu o le "Tulafono o Femalagaaʻiga Mataʻutia" a le Matagaluega o Taʻavale. E tatau ona maeʻa le faʻapipiʻiina ma e tatau ona saogalemu le utaina. I le taimi o felauaiga, ia mautinoa o le atigipusa e le tafe, paʻu, pa'ū pe faʻaleagaina. O le ta'avale (tank) o lo'o fa'aaogaina i felauaiga e tatau ona i ai se filifili fa'avae, ma e mafai ona fa'atulaga se pu vaeluaga i totonu o le ala e fa'aitiitia ai le eletise fa'atutu e mafua mai i le te'i. E matua fa'asa ona fa'afefiloi ma vaila'au fa'ama'i, alkali ma mea'ai. O felauaiga i luga o le alatele e tatau ona mulimulitaʻi i le auala faʻatonu, aua le nofo i nofoaga e nonofo ai ma toʻatele tagata.
