Ko tā mātou kamupene he mahi pono, he mahi ki ā mātou kiritaki katoa, me te mahi tonu i roto i ngā hangarau hou me ngā mīhini hou mō tētahi o ngā mea tino wera mō Haina. Hokona te CAS 79-09-4 Propionic Acid me te Utu wheketere, Ka whakapau kaha mātou ki te whakatutuki, ki te hipa rānei i ngā hiahia o ngā kiritaki me ngā taonga kounga teitei, ngā ariā matatau, me te kamupene whai hua me te wā tika. E mihi ana mātou ki ngā kiritaki katoa.
Ko tā mātou kamupene he mahi pono, he mahi ki ā mātou kiritaki katoa, me te mahi tonu i roto i ngā hangarau hou me ngā mīhini hou mō te wā roa. Ko mātou tō hoa pono i ngā mākete o te ao mō ā mātou taonga hokohoko. Ka arotahi mātou ki te whakarato ratonga ki ā mātou kiritaki hei wāhanga matua o te whakapakari i ō mātou whanaungatanga mō te wā roa. Mā te wātea tonu o ngā taonga hokohoko kounga teitei me tā mātou ratonga pai i mua i te hoko me muri i te hoko ka whakarite kia kaha te whakataetae i roto i te mākete e piki haere ana te ao. Kua pai mātou ki te mahi tahi me ngā hoa pakihi mai i te kāinga me tāwāhi, kia waihangahia he heke mai pai. Nau mai ki te toro mai ki tō mātou wheketere. Kei te tumanako mātou ki te mahi tahi ki a koe.
I roto i ngā otinga wai, ka wehea ā-wāhanga te ngota hauwai i runga i te rōpū carboxyl o te waikawa propanoic hei tuku i ngā katote hauwai (ngā proton), ka waiho hei waikawa ngoikore monoprotic me te pKa o te 4.87 i te 25°C.
Ngā tauhohenga whakahāngai me ngā kakano: Ka tauhohe ki ngā kakano hei hanga i ngā propionate e rite ana.
Me te hauwai konutai: CH₃CH₂COOH + NaOH → CH₃CH₂COONa + H₂O
Me te konupūmā hauwaiwai: 2 CH₃CH₂COOH + Ca(OH)₂ → (CH₃CH₂COO)₂Ca + 2 H₂O
Me te wai haukini: CH₃CH₂COOH + NH₃·H₂O → CH₃CH₂COONH₄ + H₂O
Ngā tauhohenga nekehanga takirua me ngā tote waikawa ngoikore: Ka tauhohe ki ngā kāponā hei tuku i te hauhā waro: 2 CH₃CH₂COOH + CO₃²⁻ → 2 CH₃CH₂COO⁻ + H₂O + CO₂↑
Te waikura ki ngā konganuku: Nā te ngoikore o te waikawa, ka waikura te waikawa propanoic ki te maha o ngā konganuku, pērā i te rino me te konupora, ka puta he hau hauwai me ngā propionate konganuku.
