Hoʻolauna

ʻO 1-(2-bromo-4-chroophenyl) ethanone (1-(2-bromo-4-chroophenyl) etanone) he mea hoʻohuihui mea ola nona ke kinikini C8H6BrClO. Eia ka wehewehe ʻana o nā waiwai, hoʻohana, hoʻomākaukau a me ka ʻike palekana o ka pūhui:

 

ʻAno:

-Nani: 1-(2-bromo-4-chroophenyl) etanone he kala ʻole a melemele iki paha.

-Ka helu heheʻe: ma kahi o 43-46 ℃.

-Pila paila: ma kahi o 265 ℃.

-Density: ma kahi o 1.71g/cm³.

-Solubility: Hiki ke hoʻoheheʻe ʻia i loko o ka wai, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, ether a me ka chloroform.

 

E hoʻohana:

- Hiki ke hoʻohana ʻia ka 1-(2-bromo-4-chroophenyl) etanone ma ke ʻano he mea waena a i ʻole he mea hoʻomaka no ka synthesis organik. Hiki ke hoʻohana ʻia e synthesize i nā pūhui ʻē aʻe, e like me nā pūhui heterocyclic.

-Ma ka lāʻau lapaʻau, hiki ke hoʻohana ʻia e hoʻomākaukau i kekahi mau lāʻau lapaʻau.

 

Kaʻina hoʻomākaukau:

Hiki ke hana ʻia ke ʻano o ka hoʻomākaukau ʻana i ka 1-(2-bromo-4-chlorophenyl)ethanone e nā ʻanuʻu aʻe:

1. E hoʻoheheʻe i ka acetophenone (acetophenone) i loko o ka waiʻona waiʻona anhydrous.

2. E hoʻohui i ka nui kūpono o ka ammonium bromide (ammonium bromide) a me ka chlorobromic acid (hypochlorous acid).

3. E hoʻoneʻe ma ka hoʻomehana ʻana i ka hui ʻana.

4. Ma hope o ka pau ʻana o ka hopena, hiki ke loaʻa i ka huahana i koho ʻia e ka crystallization a me ka hoʻomaʻemaʻe.

 

ʻIke palekana:

- ʻO 1-(2-bromo-4-chlorophenyl)ethanone he mea hoʻohuihui synthetic organika a pili i nā kaʻina hana palekana.

-I ka wā o ka hoʻohana ʻana a me ka mālama ʻana, pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā oxidants ikaika a me nā mea hiki ke ahi.

-No ka mea he kemika ia, pono e lawe ʻia nā ʻano palekana kūpono a me nā lula i ka wā e hoʻomākaukau ai, mālama a hoʻolei ʻia paha.
