Acetic Acid Mo Fa'aaogāga Alamanuia

Acetic acid, lea e ta'ua o le acetic acid, o se fa'aputu fa'aola e tele ma fa'aoga i pisinisi eseese. O lo'o iai le fuala'au fa'ama'i CH3COOH ma ose vaila'au monobasic fa'aletino o le elemene autu lea i le vineka. O le sua vai e leai ni lanu e liua i se foliga tioata pe a fa'amaua ma fa'atatauina ose mea fa'a'a'ona la'ititi ma sili ona pala. E tatau ona taulimaina ma le faaeteete ona e ono afaina ai mata ma isu.

Fa'aoga

O se tasi o faʻaoga autu o le acetic acid o loʻo i le gaosiga o le acetic anhydride, acetate esters, ma le cellulose acetate. O nei mea e maua mai e faʻaaogaina lautele i totonu o pisinisi faʻapipiʻi ma fesoasoani i le atinaʻeina o tulaga maualuga, paʻu umi. Acetic anhydride o se mea taua i le gaosiga o faʻasao fafie, aʻo faʻaaogaina le cellulose acetate i le gaosiga o vali, faʻamuamua ma varnishes. E ala i le faʻaaogaina o oloa faʻavae acetate, e mafai e pisinisi ona faʻaleleia le aoga, umi ma le faʻatosina atoa o latou faʻapipiʻi talosaga.

E le gata i lea, o le acetic acid e faʻaaogaina lautele i le gaosiga o acetates. Acetate o loʻo i ai le tele o faʻaoga faʻaoga e aofia ai le faʻaaogaina o se solvent i le gaosiga o vailaʻau eseese, aemaise lava ile falemaʻi ma vailaʻau faʻamalosi lelei. E le gata i lea, e mafai ona faʻaaogaina e avea o se mea mataʻutia i le gaosiga o mea faʻapipiʻi, paʻu ma palasitika. O oloa acetate e lauiloa mo lo latou mama maualuga, mautu ma le agavaʻa, ma avea ai i latou ma filifiliga sili ona lelei mo le tele o manaʻoga tau pisinisi.

I le faʻaopoopoga i nei faʻaoga, o le acetic acid o se mea taua i suʻesuʻega suʻesuʻe, faʻasologa o meaola, ma le faʻaogaina o pigments ma vailaʻau. O ona meatotino e mafai ai ona faʻafaigofie gaioiga faʻasolosolo eseese ma faʻagasologa synthetic. E fesoasoani i le gaosia o lanu e fa'aaogaina i vali, vaitusi ma vali, e maua ai lanu viia ma tumau. E le gata i lea, o le acetic acid o loʻo faʻaaogaina i vailaʻau faʻapipiʻi ma e iai sona sao taua i le atinaʻeina o vailaʻau e faʻaleleia ai le lelei o le olaga o tagata taʻitoʻatasi i le lalolagi atoa.

I le fa'ai'uga, o le acetic acid o se fa'alapotopotoga fa'apitoa taua ma se nofoaga i le tele o alamanuia. O ana talosaga e amata mai i le gaosiga o le acetic anhydride, acetates ma le cellulose acetates mo le fale vali i suʻesuʻega suʻesuʻe, faʻasologa o meaola ma le faʻaogaina o pigments ma vailaʻau. Faatasi ai ma ona uiga eseese ma galuega, o le acetic acid ua faamaonia o se mea taua mo pisinisi o loʻo vaʻavaʻai e faʻaleleia a latou oloa ma gaioiga. Ae ui i lea, e taua le taulimaina ma le faaeteete o le acetic acid ona e pala ma e ono afaina ai.
