Hoʻolauna

ʻO ka 2,4-Dibromobenzoic acid he mea hoʻohuihui. He keʻokeʻo keʻokeʻo a i ʻole ka pauka crystalline. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka 2,4-dibromobenzoic acid:

 

ʻAno maikaʻi:

- Ke ʻano: nā keʻokeʻo keʻokeʻo a i ʻole ka pauka crystalline.

- Solubility: Hiki ke hoʻoheheʻe ʻia e like me ka ethanol, ether a me chloroform, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.

 

E hoʻohana:

- Hiki ke hoʻohana ʻia ma ke ʻano he antioxidant a me ka hoʻohui ʻana i ka lāʻau, ma waena o nā mea ʻē aʻe.

 

Hanana:

- ʻO ke ʻano o ka hoʻomākaukau ʻana o ka waikawa 2,4-dibromobenzoic i loaʻa nui ʻia e ka hopena bromination o ka waikawa benzoic. Ma ke kaʻina kikoʻī, hana mua ka ʻakika benzoic me ka bromine i mua o kahi mea hoʻoheheʻe waika e hana i ka waikawa bromobenzoic. A laila, hydrolyzed ka waika bromobenzoic e hāʻawi i ka waikawa 2,4-dibromobenzoic.

 

ʻIke palekana:

- 2,4-Dibromobenzoic acid ka mea paʻa i ka lumi wela, akā hiki ke hoʻoheheʻe i nā wela kiʻekiʻe a i ʻole nā ​​lapalapa ahi e hana i nā kinoea ʻona.

- He mea hoʻonāukiuki a hiki ke hoʻoulu i ka huhū a me ka pilikia i ka piliʻana me kaʻili, nā maka, a me ka'ōpū hanu.

- Pono e lawe ʻia nā hana pale pilikino e like me nā mīkina lima pale, ka pale maka, a me nā mea pale hanu i ka wā e hoʻohana ai, mālama ʻia, a mālama ʻia.

- Pono e hoʻokaʻawale ʻia mai nā kumu ahi a me nā mea oxidizing a mālama ʻia ma kahi anuanu a me ka makani.
