Hoʻolauna
ʻO 2-Fluoro-4-bromobenzyl bromide he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:
ʻAno maikaʻi:
- Ke ʻano: 2-Fluoro-4-bromobenzyl bromide he wai kala ʻole a ʻeleʻele melemele.
- Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā ʻona a me nā ethers, akā hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
E hoʻohana:
- Hoʻohana pinepine ʻia ka 2-Fluoro-4-bromobenzyl bromide ma ke ʻano he koʻikoʻi koʻikoʻi i ka synthesis organik.
- Hiki ke hoʻohana ʻia kēia pūhui ma ke ʻano he mea maka no nā catalysts a me nā surfactants.
Hanana:
ʻO ke ʻano o ka hoʻomākaukau ʻana o 2-fluoro-4-bromobenzyl bromide penei:
- Ka hopena o ka waiʻona 2-bromobenzyl me ka 2,4-difluorobenzoic acid, catalyzed e ka alkali, i ka mahana kūpono a me nā kūlana manawa.
- Ma hope o ka pau ʻana o ka hopena, hoʻomaʻemaʻe ʻia a hoʻokaʻawale ʻia e ka crystallization a i ʻole distillation e loaʻa ai ka 2-fluoro-4-bromobenzyl bromide me ka maʻemaʻe kiʻekiʻe.
ʻIke palekana:
- ʻO ka 2-Fluoro-4-bromobenzyl bromide he mea hoʻoheheʻe ʻia a pono e pale ʻia kona mau mahu ma ka inhalation.
- E hoʻohana i nā lako pale pilikino kūpono e like me nā makaaniani pale, nā mīkina lima a me nā ʻaʻahu lab i ka wā o ka lawelawe ʻana a me ka lawelawe ʻana.
- I ka mālama ʻana a me ka hoʻohana ʻana, e pale i ka hoʻopili ʻana me nā oxidants, nā ʻakika ikaika, nā alkali ikaika a me nā mea ʻē aʻe e pale aku i nā hopena pōʻino.
- I ka mālama ʻana a me ka hoʻokuʻu ʻana iā ia, pono e mālama ʻia nā kānāwai kūpono, nā lula a me nā lula palekana.
