Hoʻolauna
ʻO Furfural, i ʻike ʻia ʻo 2-hydroxyunsaturated ketone a i ʻole 2-hydroxypentanone. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o furfural:
ʻAno maikaʻi:
- He ʻano kala ʻole kona ʻano a he ʻono ʻono kūikawā.
- He haʻahaʻa ko Furfural i ka wai, akā hiki ke hoʻoheheʻe ʻia i ka waiʻona a me nā solvents ether.
- He mea maʻalahi ka Furfural a hoʻoheheʻe ʻia e ka wela.
Hanana:
- Loaʻa ke ʻano hana maʻamau no ka hoʻomākaukau ʻana i ka furfural ma o ka hoʻohemo ʻana o C6 alkyl ketones (eg, hexanone).
- No ka laʻana, hiki ke hoʻokahe ʻia ka hexanone i furfural me ka hoʻohana ʻana i ka oxygen a me nā catalysts e like me ka potassium permanganate a i ʻole hydrogen peroxide.
- Eia kekahi, hiki ke hoʻopili ʻia ka ʻakika acetic me nā ʻano waiʻona C3-C5 (e like me ka isoamyl alcohol, etc.) e hana i ka ester pili, a laila hoʻemi ʻia e loaʻa ai ka furfural.
ʻIke palekana:
- He haʻahaʻa ko Furfural akā pono e hoʻohana a mālama ʻia me ka mālama.
- Hōʻalo i ka pili ʻana me ka ʻili a me nā maka, a holoi koke me ka wai nui inā pili.
- Pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā oxidants ikaika, nā kumu hoʻāla, a me nā mea ʻē aʻe i ka wā o ka waiho ʻana a me ka hoʻohana ʻana e pale i ke ahi a i ʻole pahū.
- Pono e hāʻawi ʻia nā kūlana ea maikaʻi i ka wā e hoʻohana ai i mea e pale ai i ka inhalation o nā mahu furfural.
