Hoʻolauna
ʻO 2,4-Difluorophenylacetonitrile kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2,4-difluorophenylacetonitrile:
ʻAno maikaʻi:
- Ke ʻano: wai kala ʻole
- Hiki ke hoʻoheheʻe ʻia: Hiki ke hoʻoheheʻe ʻia i loko o ka hapa nui o nā mea hoʻoheheʻe kūlohelohe e like me nā ʻawaʻawa, ethers, a me nā ketones
E hoʻohana:
- Hoʻohana pinepine ʻia ʻo 2,4-Difluorophenylacetonitrile ma ke ʻano he waena i ka synthesis organik a hiki ke hoʻohana ʻia e hoʻomākaukau i kāna mau derivatives.
Hanana:
- ʻO ke ʻano o ka hoʻomākaukau ʻana o 2,4-difluorophenylacetonitrile e loaʻa pinepine ʻia e ka phenylacetonitrile fluorinated. ʻO nā ʻanuʻu kikoʻī e pili ana i ka hana ʻana i ka phenylacetonitrile me ka chloride kālā a laila fluorinating me kahi mea hana fluorinating e like me ka palladium hydrogen hydride.
ʻIke palekana:
- ʻO 2,4-Difluorophenylacetonitrile he mea hoʻohui kūlohelohe a pono e pale ʻia mai ka inhalation, ka ʻili a me ka pili maka. E hoʻohana mau i nā mea pale pilikino e like me nā mīkina lima, nā maka pale, a me nā lole pale ke hoʻohana ʻia.
- Inā pili me ka ʻili a i ʻole nā maka, holoi koke me ka wai nui no ka liʻiliʻi loa he 15 mau minuke a ʻimi koke i ka lāʻau lapaʻau.
- Hōʻalo i ka hui ʻana me nā oxidants ikaika a me nā waikawa e pale aku i nā hopena pōʻino.
- E hoʻopaʻa paʻa ʻia a mamao i ka wela a me ke ahi.
