Hoʻolauna

2,4′-Dibromoacetophenone. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

 

ʻAno maikaʻi:

- Ke ʻano: 2,4′-Dibromoacetophenone he kala ʻole a melemele paha.

- Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ethanol, ether, a me benzene.

- Paʻa paʻa: 2,4′-Dibromoacetophenone ka mea paʻa i ka lumi wela, akā hiki ke hoʻopau ʻia i nā wela kiʻekiʻe a ke ʻike ʻia i nā lapalapa ahi.

 

E hoʻohana:

- 2,4′-Dibromoacetophenone ka mea maʻamau i hoʻohana ʻia ma ke ʻano he waena i ka synthesis organik i loko o nā laboratories kemika.

- Hiki ke hoʻohana ʻia i loko o kekahi mau ʻano hoʻohālikelike kūlohelohe, e like me nā hopena kemika organometallic a me nā hopena organocatalytic.

 

Hanana:

- 2,4′-dibromoacetophenone hiki ke hana maʻamau e ka bromination o benzophenone. Ma hope o ka hopena o ka benzophenone me ka bromine, hiki ke hoʻomākaukau ʻia ka huahana i hoʻopaʻa ʻia e ka hana hoʻomaʻemaʻe kūpono.

 

ʻIke palekana:

- He mea weliweli ka 2,4′-Dibromoacetophenone a pono e hoʻohana ʻia e like me nā kaʻina hana palekana.

- Hōʻalo i ka hoʻopili ʻana me ka ʻili, nā maka, a me ka ʻōpū hanu e pale ai i ka huhū a me ka ʻeha.

- E noʻonoʻo i nā kūlana ventila maikaʻi i ka wā e hoʻohana ai a pale i ka hoʻohu ʻana i kāna mau kinoea.

- Pono e mālama ʻia kēia pūhui a mālama ʻia mai nā lapalapa ākea a me nā kumu wela kiʻekiʻe.
