Hoʻolauna

He pūhui mea ola me ke kumu hoʻoheheʻe kemika C6H5BrN2O2. Eia ka wehewehe ʻana i kekahi o kāna mau waiwai, hoʻohana, nā ʻano a me nā ʻike palekana.

 

ʻAno:

-Ke ʻano: Paʻa keʻokeʻo keʻokeʻo.

-Ka helu hoʻoheheʻe: ma kahi o 130-132 degere Celsius.

- Ke kumu hoʻolapalapa: ma kahi o 267-268 degere Celsius.

-Solubility: Hiki ke hoʻoheheʻe ʻia i kekahi mau mea hoʻoheheʻe organik.

 

E hoʻohana:

-hiki ke hoʻohana ʻia no ka hopena synthesis organik, e like me ka cyanidation reaction, nitration reaction.

-Hoʻohana pinepine ʻia ʻo ia ma ke ʻano he koʻikoʻi koʻikoʻi no ka synthesis o nā pūhui organik ʻē aʻe.

-Ma ke kahua o ka noiʻi lāʻau, hoʻohana ʻia e hoʻomākaukau i kekahi mau lāʻau antibacterial.

 

Ke ʻano: ʻO ka hoʻohui ʻana o

Loaʻa pinepine ʻia e ka nitratation o pyridine. Hoʻopili mua ʻia ka Pyridine me ka waikawa nitric a me ka waikawa sulfuric concentrated, a laila mālama ʻia me ka solution hydrogen bromide no ka loaʻa ʻana o ka huahana i manaʻo ʻia.

 

ʻIke palekana:

-ʻo ia ka mea hoʻohui kino me kahi ʻano o ka pōʻino. E hoʻohana i nā mīkina lima pale a me nā makaaniani i ka wā o ka hana e pale aku i ka pili pono ʻana me ka ʻili a me nā maka.

-E hōʻalo i ka hoʻohu ʻana i ka lepo a i ʻole ke kinoea a hana i loko o kahi keʻena hoʻokolohua maikaʻi.

- He teratogenic, carcinogenic a i ʻole nā ​​​​hopena pōʻino ʻē aʻe o ka hui i ke kanaka, no laila e mālama pono ʻia nā kaʻina hana palekana kūpono. I ka hui 'ana a inhalation ma hope o overdose, pono manawa lapaʻau lapaʻau.
