ʻO kā mākou ʻoihana e hana pono ana, e lawelawe ana i kā mākou mea kūʻai aku āpau, a e hana mau ana i ka ʻenehana hou a me ka mīkini hou no kekahi o nā mea wela loa no Kina. E kūʻai aku iā CAS 79-09-4 Propionic Acid me ke kumukūʻai hale hana, e hana mākou i ka mea maikaʻi loa e hoʻokō a ʻoi aku paha i nā koi o nā mea kūʻai aku me nā mea kiʻekiʻe loa, ka manaʻo holomua, a me ka hui huahua a me ka manawa kūpono.

ʻO ka pahuhopu o kā mākou hui e hana me ka kūpaʻa, e lawelawe ana i kā mākou mea kūʻai aku a pau, a e hana mau ana i nā ʻenehana hou a me nā mīkini hou no, ʻO mākou kou hoa hilinaʻi ma nā mākeke honua o kā mākou waiwai kūʻai.

I loko o nā hopena wai, hoʻokaʻawale hapa ʻia ka ʻātoma hydrogen ma ka hui carboxyl o ka waikawa propanoic e hoʻokuʻu i nā ion hydrogen (protons), e lilo ia i waikawa nāwaliwali monoprotic me ka pKa o 4.87 ma 25°C.
Nā hopena neutralization me nā kumu: Hana ia me nā kumu e hana i nā propionates pili.
Me ka sodium hydroxide: CH₃CH₂COOH + NaOH → CH₃CH₂COONa + H₂O
Me ka calcium hydroxide: 2 CH₃CH₂COOH + Ca(OH)₂ → (CH₃CH₂COO)₂Ca + 2 H₂O
Me ka wai ʻamonia: CH₃CH₂COOH + NH₃·H₂O → CH₃CH₂COONH₄ + H₂O
Nā hopena hoʻoneʻe pālua me nā paʻakai waikawa nāwaliwali: Hana ia me nā carbonates e hoʻokuʻu i ke kalapona ʻokikene: 2 CH₃CH₂COOH + CO₃²⁻ → 2 CH₃CH₂COO⁻ + H₂O + CO₂↑
Ka palaho i nā metala: Ma muli o kona ʻakika nāwaliwali, palaho ka waikawa propanoic i nā metala he nui, e like me ka hao a me ka magnesium, e hana ana i ke kinoea hydrogen a me nā propionates metala.
