2 5-Dichloropyridine（CAS# 16110-09-1) Introduction
ʻO ka 2,5-dichloropyridine he mea hoʻohuihui mea ola me ke ʻano kemika C7H4Cl2N. ʻO kēia ka hoʻolauna ʻana i kekahi o kāna mau waiwai, hoʻohana, nā ʻano a me nā ʻike palekana: Nature:
-Ke ʻano: ʻAʻohe kala i ka crystalline melemele māmā a i ʻole ka wai.
-Solubility: Hiki ke hoʻoheheʻe ʻia e like me ka ethanol, chloroform a me dichloromethane, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
-Ka helu heheʻe: Ma kahi o -11 ℃.
-Pila paila: Ma kahi o 139-142 ℃.
-Density: ma kahi o 1.36g/cm³.Hoʻohana:
-Ma ke ʻano he catalyst a i ʻole solvent i nā hopena kemika.
-hoʻohana ʻia e like me nā mea maka i ka synthesis organik, e like me ka hoʻomākaukau ʻana i nā pūhui ʻē aʻe.
-hiki ke hoʻohana ʻia ma ke ʻano he waena i ka synthesis lāʻau.
- Hiki ke hoʻomākaukau ʻia ka 2,5-dichloropyridine e ka chlorination o pyridine. ʻIke palekana:
ʻO -2,5-dichloropyridine kahi hui kūlohelohe me kekahi mau mea ʻawaʻawa a pono e hoʻohana me ka mālama.
-E hōʻalo i ka pili ʻana me ka ʻili, nā maka a me nā membrane mucous. Inā pili, holoi koke me ka wai nui.
- Pono e hāʻawi ʻia nā lako pale pilikino e like me nā aniani palekana, nā mīkina lima a me nā lole pale ke hoʻohana ʻia.
- ka mālama ʻana, pono e hoʻopaʻa ʻia, ma kahi maloʻo a maloʻo, kahi mamao mai nā mea puhi ahi a me nā mea ʻona.
-Ke ʻano: ʻAʻohe kala i ka crystalline melemele māmā a i ʻole ka wai.
-Solubility: Hiki ke hoʻoheheʻe ʻia e like me ka ethanol, chloroform a me dichloromethane, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.

-Ma ke ʻano he catalyst a i ʻole solvent i nā hopena kemika.
-hoʻohana ʻia e like me nā mea maka i ka synthesis organik, e like me ka hoʻomākaukau ʻana i nā pūhui ʻē aʻe.
-hiki ke hoʻohana ʻia ma ke ʻano he waena i ka synthesis lāʻau.
- Hiki ke hoʻomākaukau ʻia ka 2,5-dichloropyridine e ka chlorination o pyridine. ʻIke palekana:
ʻO -2,5-dichloropyridine kahi hui kūlohelohe me kekahi mau mea ʻawaʻawa a pono e hoʻohana me ka mālama.

E ʻoluʻolu e ʻokoʻa iki ke ʻano kikoʻī, hoʻohana a me ka ʻike palekana o 2,5-dichloropyridine ma muli o ke kumu a me ka hoʻohana. Ma mua o ka hoʻohana pono ʻana, pono e kūkākūkā pono ʻia nā pepa ʻikepili palekana waiwai (MSDS) a me nā manual hana, a pono e hahai ʻia nā hana palekana lab pono.
E kākau i kāu leka ma aneʻi a hoʻouna mai iā mākou
