Hoʻolauna

He pūhui olaola me ke kumu hoʻoheheʻe kemika C5H3BrN2O3. Eia ka wehewehe ʻana o nā waiwai, hoʻohana, hoʻomākaukau a me ka ʻike palekana o ka pūhui:

 

ʻAno:

-Nani: He melemele a ʻalani ka pauka.

-Ka helu heheʻe a me ka paila: ʻO ka helu heheʻe o ka hui ma kahi o 141-144 ° C, a ʻaʻole ʻike ʻia ka helu hoʻolapalapa.

-Solubility: He haʻahaʻa haʻahaʻa i ka wai a hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka chloroform, methanol a me ka ether.

 

E hoʻohana:

-He mea pono ia ma ke ano he mea waena i ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he synthetic raw material no nā lāʻau lapaʻau, pesticides a me nā mea ʻē aʻe.

 

Kaʻina hoʻomākaukau:

-a i ʻole hiki ke hoʻomākaukau ʻia ma ka hana ʻana i ka pyridine me ka waika bromoacetic, a laila e hana i kahi hopena nitration ma lalo o nā kūlana alkaline.

 

ʻIke palekana:

-e pōʻino paha i ke olakino ke hoʻopili ʻia me ka ʻili, nā maka a i ʻole ka inhalation. Pono e pale ʻia ka inhalation o ka lepo a me ka pili ʻana me ka ʻili. E hoʻohana i nā lako pale pilikino kūpono i ka wā e hoʻohana ai.

- Hōʻalo i ka hoʻopili ʻana me nā oxidants ikaika, nā waikawa ikaika a me nā mea ʻē aʻe i ka wā o ka mālama ʻana a me ka lawelawe ʻana e pale aku i nā hopena pōʻino.

-I ka hoʻohana ʻana a me ka lawelawe ʻana i ka pūhui, e hahai i nā hana hoʻokolohua kūpono a me nā kaʻina hana palekana.
