Hoʻolauna

ʻO 2-Chloro-5-bromo-3-nitropyridine kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

 

ʻAno maikaʻi:

ʻO 2-Chloro-5-bromo-3-nitropyridine kahi paʻa keʻokeʻo me kahi ʻala ʻala. Loaʻa iā ia ka mea hiki ke hoʻoheheʻe ʻia a hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me nā waiʻona a me nā hydrocarbons chlorinated.

 

Hoʻohana: Hiki ke hoʻohana ʻia no ka noiʻi a me nā noi keʻena.

 

Hanana:

Hiki ke hoʻokō ʻia ke ʻano hoʻomākaukau o 2-chloro-5-bromo-3-nitropyridine ma o nā ʻano like ʻole. ʻO kahi ala maʻamau ka hoʻokō ʻana i ka chlorine a me ka bromine ma ka hoʻohui ʻana i ka alumini chloride a i ʻole nā ​​​​sulphate ʻē aʻe ma lalo o nā kūlana alkaline o 3-bromo-5-nitropyridine. Hiki ke hāʻawi ʻia nā ʻano hana synthesis kikoʻī i nā palapala kemika a i ʻole nā ​​​​limahana ʻoihana.

 

ʻIke palekana:

He mea oxidizing ikaika kēia pūhui i ka synthesis organik a pono e mālama i ka wā e mālama ai a mālama i ke ahi a pahū paha.

Hōʻalo i ka hoʻopili ʻana me nā mea puhi, nā mea hoʻohaʻahaʻa a me nā mea hiki ke ahi.

Pono e ʻaʻahu ʻia nā mea pale kūpono e like me nā mīkina lima lab, nā maka aniani, a me nā ʻaʻahu i ka wā o ka lawelawe ʻana a me ka lawelawe ʻana.

E pale i ka inhalation, ingestion, a i ʻole ka pili ʻana i ka ʻili.

Pono e hoʻomaloʻo ʻia ke mālama ʻia a pale aku i ka hoʻopili ʻana me ka wai ma ka lewa.

Ke hoʻolei ʻia, pono e hoʻolei ʻia e like me nā lula kūloko a ʻaʻole pono e hoʻolei ʻia a hoʻokuʻu ʻia i loko o ke kaiapuni.
