Hoʻolauna
ʻO 2,6-Difluorobenzonitrile, ʻike ʻia hoʻi ʻo 2,6-difluorobenzonitrile, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:
ʻAno maikaʻi:
- Nānā: 2,6-Difluorobenzonitrile he wai kala ʻole a i ʻole ke aniani keʻokeʻo.
- Solubility: Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik.
E hoʻohana:
- Hoʻohana pinepine ʻia ʻo 2,6-Difluorobenzonitrile ma ke ʻano he koʻikoʻi koʻikoʻi i ka synthesis organik, no ka laʻana he mea hoʻomaka no ka hana ʻana i nā pūhui organik ʻē aʻe.
Hanana:
- ʻO ke ʻano o ka hoʻomākaukau ʻana o 2,6-difluorobenzonitrile i loaʻa nui ʻia e ka hopena o ka 2,6-difluorobenzyl alcohol a me ka sodium cyanide i mua o kahi catalyst alkaline.
- ʻO nā hana kikoʻī e pili ana i ka hopena o ka 2,6-difluorobenzyl alcohol me ka sodium cyanide ma lalo o nā kūlana alkaline, a ukali ʻia e ka acidification e loaʻa ai ka huahana 2,6-difluorobenzonitrile.
ʻIke palekana:
- 2,6-difluorobenzonitrile he haʻahaʻa haʻahaʻa, akā pono e mālama ʻia e pale i ka hoʻopili pololei ʻana me ka ʻili, nā maka, a me ka ʻōpū hanu.
- Pono nā kaʻina hana palekana kūpono a me nā lako pale pono i ka wā e hoʻohana ai a mālama ʻia paha.
- Ke hoʻopā wale ʻia ka mea hoʻohui a i ʻole hoʻi ʻia, pono e hoʻomaʻemaʻe a hoʻoheheʻe koke ʻia a pono e ʻimi koke ʻia ka lāʻau lapaʻau.
