Hoʻolauna
ʻO ka 2,4-Difluorophenylhydrazine hydrochloride he mea hoʻohuihui me ke ʻano kemika C6H6F2N2 · HCl. Eia ka wehewehe kikoʻī o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
-Ke ʻano: paʻa kala kala ʻole
-Ka helu hoohehee: 151-153°C
-pili molecular mass: 188.59
-Soluble: Hiki ke hoʻoheheʻe ʻia i ka wai a me kekahi mau mea hoʻoheheʻe kūlohelohe, e like me ka ethanol a me ka chloroform
E hoʻohana:
Hoʻohana nui ʻia ka 2,4-Difluorophenylhydrazine hydrochloride ma ke ʻano he mea hoʻohaʻahaʻa a me kahi reagent i loko o ka nitrogen i ka synthesis organik. Hiki iā ia ke hana me kekahi mau mea hoʻohuihui e hoʻohua i nā derivatives hydrazine, e like me ka synthesis o nā quinones, a i ʻole no ka synthesis o nā pūhui heterocyclic nitrogen ʻē aʻe.
Kaʻina hoʻomākaukau:
Hiki ke hoʻomākaukau ʻia ka 2,4-Difluorophenylhydrazine hydrochloride e ka hopena o phenylhydrazine a me 2,4-difluorobenzaldehyde. ʻO nā kūlana hoʻololi maʻamau, ʻo ia ka hoʻokō ʻana i ka hopena ma kahi ʻano kumu me ka hoʻohui lohi o ka waika hydrochloric a me ka ua ma hope o ka huahana e like me ka paʻakai hydrochloride.
ʻIke palekana:
- 2,4-Difluorophenylhydrazine hydrochloride he mea ʻino ia, e ʻoluʻolu e makaʻala e pale i ka inhalation, intake a i ʻole pili me ka ʻili a me nā maka.
-E hoʻohana i nā mea pale kūpono e like me nā mīkina lima, nā respirator a me nā maka aniani i ka wā e hoʻohana ai a me ka hana.
-E ʻoluʻolu e hoʻopaʻa ʻia a pale aku i ka pili ʻana me ka ea, ka makū a me ka māmā.
-e ʻoluʻolu e hahai i nā kaʻina hana palekana lab, e pale i ke ahi a me ka ʻāʻī kokoke i ka hana.
