Hoʻolauna
ʻO 2,4-Difluorobenzaldehyde kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:
ʻAno maikaʻi:
- Ke ʻano: wai kala ʻole a melemele paha.
- Hoʻoheheʻe: hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā ʻawaʻawa, ethers a me nā hydrocarbons chlorinated.
E hoʻohana:
- Hoʻohana pinepine ʻia ʻo 2,4-Difluorobenzaldehyde ma ke ʻano he mea waena i ka synthesis o nā pūhui organik ʻē aʻe.
- Nā noi koʻikoʻi i ka synthesis o kekahi mau photosensitizers.
Hanana:
Hoʻomākaukau ʻia ka 2,4-difluorobenzaldehyde e nā ʻano hana penei:
- Hiki ke loaʻa iā ia ma ka hana ʻana i ka benzaldehyde me ka hydrogen fluoride, maʻamau ma 40-50°C.
- Hiki ke hoʻomākaukau ʻia me ka chlorobenzaldehyde me ka hydrogen fluoride a i ʻole fluorosilanes.
ʻIke palekana:
- 2,4-Difluorobenzaldehyde hiki ke hoʻonāukiuki i ka ʻili, nā maka, a me ka ʻōnaehana hanu. Pono e hoʻohana ʻia nā mea pale kūpono e like me nā mīkina lima, nā maka aniani, a me ka pale hanu i ka wā e hoʻohana ai a lawelawe ʻia paha.
- Pono e mālama ʻia mai ke ahi a me nā wela kiʻekiʻe, ma kahi ʻoluʻolu, maloʻo, maikaʻi-ventilated, a kaʻawale mai nā mea ʻokiʻoki a me nā mea alkaline ikaika.
- E nānā a hahai i nā kaʻina hana palekana kūpono ma mua o ka hoʻohana ʻana.
