Hoʻolauna

He wai kala ʻole ʻo Ethyl propionate me ka liʻiliʻi o ka wai. Loaʻa iā ia ka ʻono a me ka hua a hoʻohana pinepine ʻia ma ke ʻano he ʻāpana o nā solvents a me nā mea ʻono. Hiki i ka Ethyl propionate ke hana me nā ʻano mea like ʻole, me ka esterification, ka hoʻohui, a me ka oxidation.

 

Hoʻomākaukau ʻia ʻo Ethyl propionate ma ka ʻoihana e ka hopena esterification o ka acetone a me ka waiʻona. ʻO ka Esterification ke kaʻina hana o ka hana ʻana i nā ketones a me nā waiʻona e hana i nā esters.

 

ʻOiai he mea ʻawaʻawa ka ethyl propionate, palekana ia ma lalo o ka hoʻohana maʻamau a me nā kūlana mālama. Hiki ke puhi ʻia ka Ethyl propionate a ʻaʻole pono e hui pū ʻia me nā oxidants, nā waikawa ikaika a me nā kumu. I ka hihia o ka ingestion a i ʻole inhalation, e ʻimi koke i ka lāʻau lapaʻau.
