ʻO 2-Bromo-5-fluorotrifluorotoluene he mea hoʻohuihui.

 

He ikaika ka hydrophobicity a me ka solubility, a he paʻa kiʻekiʻe. Hiki ke hoʻohana ʻia ma ke ʻano he reagent i nā hopena kemika a hoʻohana pinepine ʻia i nā hopena hoʻololi a me nā hopena hoʻohui i ka synthesis organik.

 

Hiki ke hana maʻamau ke ʻano o ka hoʻomākaukau ʻana o 2-bromo-5-fluorotrifluorotoluene ma ka hana ʻana i ka trifluorotoluene me 2-bromophenylfluoride. Hiki ke hoʻokō ʻia ka hopena ma lalo o nā kūlana acidic a i ʻole alkaline, a hiki ke hoʻihoʻi a hoʻopau ʻia ka waika hydrofluoric a i ʻole hydrobromic acid i hana ʻia e ka hopena.

He wai wela ia me ka ʻala ʻala e hiki ai ke hoʻonāukiuki a me ka wela i ka pili ʻana me ka ʻili a me nā maka. E hoʻohana i nā mea pale kūpono i ka wā e hana ai a pale i ka pili ʻana me ka ʻili a me nā maka. Hōʻalo i ka hoʻopili ʻana me nā lapalapa ākea a i ʻole nā ​​kumu wela kiʻekiʻe. I ka wā o ka mālama ʻana a me ka hoʻohana ʻana, pono e hoʻopaʻa ʻia e pale i ka volatilization a me ka leakage ma muli o ka ʻike ʻana i ka ea. Inā he leak, pono e lawe ʻia nā hana kūpono e hoʻomaʻemaʻe a hoʻopau. I ka wā e hoʻolei ai i ka ʻōpala, pono e hoʻolei ʻia e like me nā kānāwai kūloko.
