Hoʻolauna
ʻO ka 2-Chloro-4-fluorobenzyl bromide he mea hoʻohuihui me ke ʻano kemika C7H5BrClF. He wai ʻaila melemele ʻole a ʻulaʻula paha ma ka lumi wela. Eia ka wehewehe ʻana o ke ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana o 2-Chloro-4-fluorobenzyl bromide:
ʻAno:
-Ke ʻano: kala ʻole a i ʻole ka wai ʻaila melemele māmā
-Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol a me ka dichloromethane
-Ka helu heheʻe:-10°C
-Ka Lae Pahu: 112-114°C
-Ka mānoanoa: 1.646 g/mL
E hoʻohana:
Hoʻohana pinepine ʻia ʻo 2-Chloro-4-fluorobenzyl bromide ma ke ʻano he koʻikoʻi koʻikoʻi a me nā mea maka i ka synthesis organik. Hiki ke hoʻohana ʻia i ka synthesis o nā pūhui organik ʻē aʻe, e like me nā pūhui heterocyclic, nā lāʻau lapaʻau a me nā dyes.
Kaʻina hoʻomākaukau:
Hiki ke hoʻomākaukau ʻia ka 2-Chloro-4-fluorobenzyl bromide ma ka hana ʻana i ka waiʻona 2-chloro-4-fluorobenzyl me ka hydrogen bromide. ʻO ka mua, ua hoʻokahe ʻia ka waiʻona 2-chloro-4-fluorobenzyl me ka hydrogen bromide i mua o kahi kumu e hana ai i ka 2-chloro-4-fluorobenzyl bromide. A laila, hoʻomaʻemaʻe ʻia e ka unuhi ʻana me ka waika hydrochloric concentrated a me ka distillation no ka loaʻa ʻana o ka huahana pahuhopu 2-Chloro-4-fluorobenzyl bromide.
ʻIke palekana:
Pono e mālama ʻia kēia mau mea palekana i ka wā e hoʻohana ai a lawelawe paha i ka 2-Chloro-4-fluorobenzyl bromide:
-E hōʻalo i ka pili ʻana me ka ʻili, nā maka a me nā membrane mucous. Inā pili, holoi me ka wai nui a ʻimi i ka lāʻau lapaʻau.
-I ka wā o ka hana, e hoʻohana i nā mea pale pono, e like me nā mīkina lima pale, nā aniani palekana a me nā lole pale.
-E hōʻalo i ka hanu ʻana i kona mahu a lepo paha. I ka wā o ka hana, pono e hōʻoia ʻia aia ma kahi wahi i hoʻoluʻu maikaʻi ʻia.
- Pono e hoʻopaʻa ʻia ka mālama ʻana e pale aku i ka hoʻopili ʻana me nā oxidants a me nā waikawa ikaika / alkalis.
