Hoʻolauna

ʻO 2-Fluoro-4-bromobenzaldehyde kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o kēia pūhui:

 

ʻAno maikaʻi:

- Ke ʻano: 2-Fluoro-4-bromobenzaldehyde he kala ʻole i ka paʻa melemele.

- Solubility: Hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe polar e like me ka ethanol a me ka methylene chloride.

- Paʻa: ʻO 2-Fluoro-4-bromobenzaldehyde kahi hui paʻa ʻole e hoʻopili maʻalahi ʻia e ka māmā a me ka wela a hiki ke hoʻoheheʻe ʻia e ka wela.

 

E hoʻohana:

- Hiki ke hoʻohana ʻia i nā wahi e like me ka synthesis dye, catalysts, a me nā mea optical.

 

Hanana:

Hiki ke hana ʻia ka 2-Fluoro-4-bromobenzaldehyde e nā ʻano hana like ʻole, e like me:

Hiki ke hoʻopili ʻia ka waiʻona 2-bromo-4-fluorobenzyl me kahi hopena acidic, hiki ke hoʻokaʻawale ʻia ka hopena hopena a hoʻoheheʻe ʻia no ka loaʻa ʻana o kahi huahana hoʻomaʻemaʻe.

Hiki ke loaʻa ma ka oxidizing 4-fluorostyrene i mua o ka ethyl bromide.

 

ʻIke palekana:

ʻO 2-Fluoro-4-bromobenzaldehyde he mea hoʻohuihui mea ola e pono ai i nā kaʻina hana palekana kūpono a me nā ana e mālama ʻia i:

- He mea hoʻonāukiuki ka 2-Fluoro-4-bromobenzaldehyde a hiki ke hōʻeha i ka maka, ka ʻili, a me ka ʻōpū hanu. I ka wā e hana ai, pono e hoʻokomo i nā mea pale kūpono e like me nā aniani, nā mīkina lima a me nā maka.

- Hōʻalo i ka hoʻohu ʻana i nā mahu mai kā lākou kinoea a i ʻole nā ​​​​mea hoʻonā. Pono e hoʻohana a hoʻohana ʻia paha nā kiaʻi ma kahi wahi i hoʻoluʻu maikaʻi ʻia.

- Hōʻalo i ka ʻike ʻana i ka lā a i ʻole ka wela. Pono e mālama ʻia ma kahi maloʻo a maloʻo e pale aku i ka hoʻopili ʻana me nā mea ʻokiʻoki.

- Mai hoʻohui i ka 2-fluoro-4-bromobenzaldehyde me nā mea hoʻoheheʻe ikaika a ʻaʻole e hoʻokuʻu i loko o nā kino wai a i ʻole nā ​​​​kaiapuni ʻē aʻe.

 

Ma mua o ka hoʻohana ʻana i ka 2-fluoro-4-bromobenzaldehyde, e heluhelu a hoʻomaopopo ʻoe i nā pepa ʻikepili palekana kūpono a me nā manual hana, a e hahai i nā hana kūpono a me ka hoʻokuʻu ʻana.
