Hoʻolauna
ʻO 2,5-Dimethylfuran kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2,5-dimethylfuran:
ʻAno maikaʻi:
- Ke ʻano: 2,5-Dimethylfuran he wai kala ʻole me kahi ʻala ʻokoʻa.
- Hoʻoheheʻe: hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ethanol a me ka ether, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
- Paʻa: Paʻa ia i ka mahana o ka lumi, akā pono e pale ʻia mai ka mālamalama a hoʻopaʻa ʻia.
E hoʻohana:
- Hoʻohana pinepine ʻia ka 2,5-dimethylfuran ma ke ʻano he solvent i ka ʻoihana kemika, ʻoi aku ka nui no ka hoʻopau ʻana i nā pūhui polymer, e like me nā polymers, resins, etc.
Hanana:
- Hiki ke hoʻomākaukau ʻia ka 2,5-Dimethylfuran e ka hopena o ka furan me ka ethylene. ʻO ka mea mua, lawe ʻia ka hopena hoʻohui o ka furan a me ka ethylene ma lalo o ka hana a ka acid catalyst, a laila lawe ʻia ka hopena alkali-catalyzed e hana i ka 2,5-dimethylfuran.
ʻIke palekana:
- ʻO 2,5-Dimethylfuran ka mea hoʻonāukiuki a me ka narcotic, a hiki ke loaʻa ka hopena hoʻonāukiuki i ka ʻili, nā maka, a me ka ʻōnaehana hanu.
- Pono e mālama ʻia no ka ʻike ʻana, e like me ke komo ʻana i nā mīkina lima pale kūpono, nā aniani, a me nā maka.
- Hōʻalo i ka pili ʻana me ke ahi, e makaʻala i ka ea i ka wā e mālama ai, a e haʻalele i nā oxidants.
- Ke hoʻohana a lawelawe ʻana paha i ka 2,5-dimethylfuran, e hahai i nā kaʻina hana palekana kūpono a pale i ka inhalation, ingestion, a i ʻole pili.
