Hoʻolauna

ʻO ka 2-Bromo-5-nitrobenzoic acid he mea hoʻohuihui kino me ke ʻano kemika C7H4BrNO4. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.

 

ʻAno:

- 2-Bromo-5-nitrobenzoic acid he aniani paʻa melemele, ʻaʻohe ʻala.

-ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai ma ka lumi wela, akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol, chloroform a me dimethyl sulfoxide.

-He kūlana kūpaʻa kona, akā hiki iā ia ke hana i mua o nā oxidants ikaika.

 

E hoʻohana:

- Hoʻohana pinepine ʻia ka 2-Bromo-5-nitrobenzoic acid ma ke ʻano he koʻikoʻi koʻikoʻi i nā hopena synthesis organik.

-Hiki iā ia ke hana me nā mea hoʻohui ʻē aʻe e hana i nā pūhui organik hou.

-Hiki nō hoʻi ke hoʻohana ʻia e hoʻomākaukau i nā dyes fluorescent, pesticides a me nā lāʻau lapaʻau.

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka waikawa 2-Bromo-5-nitrobenzoic e nā ʻanuʻu aʻe:

1. Hoʻopili ʻia ka ʻakika benzoic me ka waikawa nitric concentrated no ka loaʻa ʻana o ka waikawa nitrobenzoic.

2. hoʻohui i ka bromine e hana me ka nitrobenzoic acid ma lalo o nā kūlana kūpono e hoʻohua ai i ka 2-Bromo-5-nitrobenzoic acid.

 

ʻIke palekana:

- ʻO ka 2-Bromo-5-nitrobenzoic acid he mea hoʻohuihui kūlohelohe, a pono e uku ʻia i kona ʻona.

-Ma ka hana, pono e komo i nā aniani pale a me nā mīkina lima, e pale i ka ʻili.

-E hana i loko o kahi kaiapuni maikaʻi e pale aku ai i ka hanu ʻana i ka lepo a i ʻole ke kinoea mai ka mea.

-Inā lawe hewa ʻia ka nui o ka waiwai a inhaled paha, e nīnau koke i ke kauka a haʻi i ke kauka i ke kūlana.

-E mālama i ke ahi a me ka wela a mālama i kahi maloʻo a maloʻo.
