Hoʻolauna

ʻO ka 2,3,5-Tribromopyridine he mea hoʻohuihui kūlohelohe me ke ʻano kemika C5H2Br3N. ʻO kēia ka hoʻolauna ʻana i kekahi o kāna mau waiwai, hoʻohana, hana a me ka ʻike palekana.

 

ʻAno:

-Nani: 2,3,5-Tribromopyridine he kala ʻole a ʻeleʻele melemele.

-Solubility: ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me chloroform, dichloromethane, etc.

-Ka helu hoʻoheheʻe: 2,3,5-Tribromopyridine kahi helu heheʻe ma kahi o 112-114 ° C.

 

E hoʻohana:

- Hoʻohana pinepine ʻia ʻo 2,3,5-Tribromopyridine ma ke ʻano he reagent a waena i ka synthesis organik.

-Hoʻohana nui ʻia ia i nā kula o ka synthesis lāʻau, ka hana pesticide a me ka hoʻomākaukau ʻana i ka wai.

-Eia kekahi, hiki ke hoʻohana ʻia i mea hoʻomaka no ka synthesis o nā pūhui organik metala (me nā polymers coordination a me nā mea photoelectric).

 

Kaʻina hoʻomākaukau:

Hiki ke hoʻokō ʻia ke ʻano o ka hoʻomākaukau ʻana o 2,3,5-Tribromopyridine e nā ʻanuʻu aʻe:

ʻO ka mua, hoʻoheheʻe ʻia ka pyridine i loko o kahi mea hoʻoheheʻe organik e like me dichloromethane a i ʻole chloroform.

2. E hoʻohui i ka bromine i ka hopena a hoʻomehana i ka hopena.

3. Ma hope o ka pau ʻana o ka hopena, ua hydrolyzed ka huahana brominated me ka hoʻohui dropwise o ka wai.

4. ʻO ka hope, hoʻokaʻawale ʻia ka huahana a hoʻomaʻemaʻe ʻia e ka kānana, crystallization, etc.

 

ʻIke palekana:

- 2,3,5-Tribromopyridine ʻaʻole ia e hana i nā pilikia palekana ma lalo o nā kūlana hana maʻamau.

- Hiki ke hoʻonāukiuki i ka ʻili, nā maka a me ka ʻōpū hanu, no laila e hoʻohana i nā lako pale pilikino kūpono i ka wā e hoʻohana ai.

-E nānā i nā kaʻina hana hoʻokolohua kūpono a me nā hana palekana i ka wā e lawelawe ai i kēia pūhui.

-I ka mālama ʻana a me ka mālama ʻana i ka pūhui, pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā oxidants, nā waikawa ikaika, nā kumu ikaika a me nā mea ʻē aʻe.

 

E ʻoluʻolu e hoʻomaopopo ʻo ka ʻike ma luna nei no ka kuhikuhi wale nō. Ke hoʻohana nei i ka 2,3,5-Tribromopyridine a i ʻole kekahi mea kemika ʻē aʻe, e ʻoluʻolu e hahai i nā ʻōlelo aʻoaʻo no ka hana palekana a me ka hoʻohana pono ʻana, a heluhelu a hoʻokō i ka pepa ʻikepili palekana o ka kemika pili.
