Hoʻolauna
ʻO 2,5-Difluorobenzonitrile kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kekahi mau waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2,5-difluorobenzonitrile:
ʻAno maikaʻi:
- 2,5-Difluorobenzonitrile he aniani ʻeleʻele ʻeleʻele a ʻeleʻele me kahi ʻala ʻala.
- 2,5-difluorobenzonitrile aneane hiki ʻole ke hoʻoheheʻe ʻia i ka wai ma ka lumi wela, akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, acetone, etc.
- He hui ia me kahi ala ʻala ikaika.
E hoʻohana:
- Hoʻohana nui ʻia ka 2,5-Difluorobenzonitrile i ka synthesis organik ma ke ʻano he reagent kemika no ka hoʻomākaukau ʻana i nā pūhui organik ʻē aʻe.
- Hoʻohana maʻamau ia i nā hopena fluorination a me nā hopena aromatization no ka mea hiki i ka hoʻokomo ʻana o nā ʻātoma fluorine ke hoʻololi i nā waiwai o nā pūhui, e hoʻonui ana i kā lākou hydrophobicity a me ka paʻa kemika.
Hanana:
- Hiki ke hoʻomākaukau ʻia ka 2,5-difluorobenzonitrile e ka hopena hoʻololi ʻala. ʻO kahi ʻano hoʻomākaukau maʻamau ʻo ka hana ʻana i ka para-dinitrobenzene me nā nitrosamines i hoʻopaʻa ʻia e ka cuprous chloride a me ka waika hydrofluoric e loaʻa ai ka 2,5-difluorobenzonitrile.
ʻIke palekana:
- I ka lawelawe ʻana i ka 2,5-difluorobenzonitrile, e hoʻokomo i nā mea pale kūpono e like me nā mīkina lima pale kemika, nā maka aniani, a me ke kapa komo.
- He mea hoʻonāukiuki ia e hiki ai ke hoʻonāukiuki i ka maka, ka ʻili, a me ka ʻōpū hanu.
- Pono e pale ʻia ka inhalation o kona mahu a lepo paha, ka ʻili a me ka maka i ka wā e lawelawe ai.
- Pono e noʻonoʻo i nā hana pale ahi a pahū i ka wā o ka mālama ʻana a me ka hoʻohana ʻana, a e hoʻokaʻawale i nā kumu ahi a me nā oxidants.
