Hoʻolauna
ʻO 3,5-Difluorobenzonitrile kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kekahi mau waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 3,5-difluorobenzonitrile:
ʻAno maikaʻi:
- Ke ʻano: 3,5-Difluorobenzonitrile he wai kala ʻole i ka ʻeleʻele melemele.
- Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, ether, a me ka chloroform.
E hoʻohana:
- Hoʻohana nui ʻia ka 3,5-Difluorobenzonitrile ma ke ʻano he waena i ka synthesis organik.
- Hiki ke hoʻohana ʻia ma ke ʻano he kemika i loko o ka ʻoihana uila no ka hana ʻana i nā mea pena a me nā mea synthetic.
Hanana:
- Loaʻa ke ʻano hoʻomākaukau nui o 3,5-difluorobenzonitrile e ka hopena o 3,5-difluorophenyl bromide a me copper cyanide ma lalo o nā kūlana kūpono.
ʻIke palekana:
- 3,5-Difluorobenzonitrile he mea hoʻonāukiuki a hoʻomāinoino, a pono e lawe i nā hana palekana kūpono e like me ke komo ʻana i nā mīkina lima pale a me nā maka aniani i ka wā e hoʻohana ai.
- Hōʻalo i ka pili pono ʻana me ka ʻili a me ka inhalation o kona mau mahu, a e hana ma kahi e hoʻoheheʻe maikaʻi ʻia.
- I ka mālama ʻana a me ka mālama ʻana i ka 3,5-difluorobenzonitrile, pono e mālama ʻia e pale i ka hoʻopili ʻana me nā oxidants, alkali ikaika a me nā mea ʻē aʻe e pale ai i ka hiki ʻana mai o nā hopena weliweli.
- E nānā i nā palapala palekana kūpono a me nā alakaʻi alakaʻi i ka wā e hoʻohana ai a e lawelawe ana i kēia pūhui, a e hahai pono i nā lula pili.
