Tauhohenga waiora
Te tauhohenga ngingiha owaikawa ahetikihe tauhohenga waiora i roto i te tikanga whanui me te ngiha katoa owaikawa ahetikika whakaputa te hauhā me te kohu wai.
Tauhohenga whakakapinga
Esterification
Ka taea e te waikawa acetic me te waihano te whakamaarama i raro i te whakamaaramatanga o te waikawa pungatara me te whakamahana ki te whakaputa ethyl acetate.
α-H tauhohenga hauhautanga
I te aroaro o te ūkuikui whero, te halogen me te waikawa acetic ka taea te tauhohenga α-H halogenation.Hei tauira, ka tauhohe te waikawa ahetiki ki te hau maota i raro i te mahi a te ūkuikui whero hei hanga waikawa chloroacetic.
Tauhohenga mate wai
Ka taea e te waikawa ahetiki te uru ki te tauhohenga whakamaroketanga ngota ngota.Ma tetahi ngota ngota waikawa ahetiki ka tango i te roopu -OH, ka tangohia e tetahi atu ngota ngota waikawa ahetiki i te H, ka mutu ka hanga te anhydride acetic.
E whai ake nei ko te paerewa a-motu o te Repupiripia Tangata o Haina mo te waikawa acetic ahumahi:
| Tūemi | Tauwhāiti | ||
| Kōeke | Moni | Koeke tuatahi | Kua whai tohu |
| Chroma, Waeine Hazen (Platinum-Cobalt) ≤ | 10 | 20 | 30 |
| Te ihirangi waikawa acetic % ≥ | 99.8 | 99.0 | 98.0 |

Te tono ahumahi kai
I roto i te ahumahi kai, ka whakamahia te waikawa acetic hei acidulant, te kai reka me te kai reka ki te hanga i te winika waihanga, te waikawa acetic ki te 4-5% ki te wai, te taapiri i nga momo kai reka, he rite te reka ki te waipiro, he poto te wa hangahanga, he iti te utu.Hei kawa kawa, ka taea te whakamahi i roto i nga kinaki whakangao, hei whakarite i te winika, te kai kēne, te tiēre me te tiihi, ma te whakamahi i runga i nga hiahia whakaputa. Ka taea hoki te whakamahi hei whakanikoniko mo te waina koji, a ko te inenga he 0.1 ki te 0.3 g/kg.
Ko te kino o te waikawa acetic e pa ana ki te kukū o te waikawa waikawa waikawa.Ko te whakarōpūtanga a te EU mo nga otinga waikawa ahetiki kua whakatauirahia ki te ripanga i raro nei:
| Kukū (papatipu) | Molarity | Te māka | |
| 10%–25% | 1.67–4.16 mol/L | Whakariri(Xi) | R36/38 |
| 25%–90% | 4.16–14.99 mol/L | Te waikura(C) | R34 |
| >90% | >14.99 mol/L | Te waikura(C) | R10, R35 |
Na te kaha o te hongi me nga kohu kino, ko te mahi o te waikawa acetic me te kukū neke atu i te 25% me whakahaere i raro i te kanohi kanohi.Kare he kino nga otinga waikawa acetic, penei i te winika. o nga otinga waikawa ahetiki he kino ki te hauora o te tangata me te kararehe.
Te whakahaere rokiroki
Rokiroki i roto i te whare putunga hauhautanga, whai hau.Kia matara atu i te ahi me nga puna wera.I roto i te wa mīti, me pupuri te pāmahana rokiroki ki runga ake i te 16 ℃ kia kore ai e pakari. Kia kati te ipu.Me whakaputu motuhake mai i nga waikura me nga kawakore, kaua hoki e konatunatua.Whakamahia nga rama pahū me nga whakaurunga hau.Aukati i te whakamahi i nga taputapu miihini me nga taputapu e pa ana ki te korakora.Ko nga waahi rokiroki me whakauru ki nga taputapu tuku ohorere me nga taputapu pupuri tika.
