2-Chloro-3-bromo-5-nitropyridine（CAS# 5470-17-7)

Hoʻolauna

ʻO ia ka mea hoʻohui kemika nona ka ʻano kemika C5H2BrClN2O2.

ʻAno:

1. Nani: He paʻa, maʻamau he pauka crystalline melemele.

2. Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik (e like me dichloromethane, ether, etc.), akā haʻahaʻa ka solubility i ka wai.

E hoʻohana:

He pūhui waena koʻikoʻi ia, i hoʻohana nui ʻia ma ke kahua o ka synthesis kemika.

1. Drug synthesis: Hiki ke hoʻohana ʻia e synthesize i nā pūhui biologically active, e like me nā lāʻau lapaʻau, pesticides, etc.

2. Synthesis Dye: Hiki ke hoʻohana ʻia e synthesize i nā dyes a me nā puaʻa.

3. pesticide synthesis: hiki ke hoʻohana ʻia no nā pesticides synthetic a me nā herbicides.

Ka Papa Hana: Ka hoomakaukau ana o

Hiki ke hoʻokō ʻia e ka hopena nitration aromatic, ʻo nā ʻanuʻu kikoʻī penei:

1. Ma lalo o nā kūlana kūpono, hoʻopili ʻia ka pyridine me ka waikawa nitric concentrated e loaʻa ai ka pyridine-3-nitric acid.

2. Hoʻopili ʻia ka Pyridine-3-nitric acid me ka bromide cuprous e loaʻa ai ka 3-bromopyridine.

3. ʻO ka hope, ua hoʻopili ʻia ka 3-bromopyridine me ke kala chloride e loaʻa ai ka huahana hope.

ʻIke palekana:

1. loaʻa kekahi ʻano o ka huhū a me ka ʻawaʻawa, e ʻoluʻolu e pale i ka pili ʻana me ka ʻili, nā maka a me ka ʻōnaehana hanu.

2. i loko o ka hana, pono e komo i nā mīkina lima pale, nā maka maka maka a me nā mea pale pono'ī.

3. i ka wā o ka mālama ʻana a me ka hoʻohana ʻana, pono e mālama kaʻawale ʻia mai nā inflammables, oxidants a me nā mea ʻē aʻe.

4. I ka wā e hoʻolei ai i ka ʻōpala, e ʻoluʻolu e mālama i nā lula hoʻolei ʻōpala kūloko e hōʻemi i ka hopena o ka haumia o ke kaiapuni.
