Hoʻolauna
ʻO ka 3,4-Difluorobsyl bromide he mea hoʻohuihui me ke ʻano kemika C7H5BrF2. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
- 3,4-Difluorobenzyl bromide he wai kala ʻole.
-He 1.78g/cm³ kona mānoanoa a me kahi paila o 216-218 degere Celsius.
-Ma ka lumi wela, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ether a me ka chloroform.
E hoʻohana:
- Hoʻohana pinepine ʻia ka 3,4-Difluorobenzyl bromide ma ke ʻano he reagent i ka synthesis organik. Hiki ke hoʻohana ʻia e synthesize i nā pūhui organik me nā hale kikoʻī a me nā waiwai.
-Hiki ke hoʻohana ʻia ma ke ʻano he waena i ka lāʻau lapaʻau a me nā pesticides.
Kaʻina hoʻomākaukau:
ʻO ka hoʻomākaukau ʻana o -3,4-Difluorobenzyl bromide hiki ke loaʻa ma ka hoʻopili ʻana i ka 3,4-difluorobenzaldehyde me ka sodium bromide ma lalo o nā kūlana hopena kūpono.
ʻIke palekana:
- Pono ka 3,4-Difluorobenzyl bromide i ka mālama ʻana i ka mālama ʻana i ka wā mālama a me ka mālama ʻana.
- Pono e mālama ʻia i loko o kahi pahu i pani ʻia, e pale i ka pili ʻana me ka ea a me ka wai.
-E hoʻohana i nā mīkina lima pale kūpono a me nā aniani i ka wā e hoʻohana ai.
-E hōʻalo i ka hanu ʻana, nau a hoʻopā paha i ka ʻili i ka wā o ka hana.
-I ka wā e hoʻolei ai i ka ʻōpala, pono e mālama ʻia a hoʻolei ʻia e like me nā lula pili aupuni a me nā ʻāpana.
E ʻoluʻolu e mālama pono ʻia nā kaʻina hana palekana i ka wā e hoʻohana ai i kēia pūhui, a lawe ʻia nā hana pale kūpono e like me ke kūlana kikoʻī. Inā he nīnau hou aʻe kāu, e ʻoluʻolu e nīnau i kahi loea a i ʻole ke alakaʻi kūpono o ke keʻena kemika organik.
