Waikawa ahetiki wai kore tae CAS 64-19-7 waikawa ahetiki
Tauhohenga Redox
Tauhohenga whakaheke
Ka taea te whakaheke i te waikawa acetic ki te acetaldehyde e te lithium aluminum hydride.
Tauhohenga waiora
Te tauhohenga ngingiha owaikawa ahetikihe tauhohenga waiora i roto i te tikanga whanui me te ngingihatanga katoa o te waikawa ahetiki ka whakaputa te hauhau waro 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.
Ka tauhohe ki te ūkuikui trichloride
Ko te whakawera o te waikawa ahetiki me te ūkuikui trichloride ka taea te tauhohenga whakakapinga, ka taea e te tauhohenga te whakaputa acetyl chloride me te waikawa phosphorous.

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.
