Hoʻolauna

ʻO ka 2,5-Dichloronicotinic acid he mea hoʻohuihui me ke ʻano kemika C6H3Cl2NO2, e hoʻohana ana i kahi hoʻonohonoho liʻiliʻi liʻiliʻi imidazole i loko o kāna ʻano kala imidazolyl. Eia kekahi mau waiwai nui o ka 2,5-Dichloronicotinic acid:

 

ʻAno:

-Nani: Keʻokeʻo a i ʻole melemele ʻeleʻele paʻa.

-Ka helu hehee: ma kahi o 207-208°C.

-Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka waiʻona, ether, chloroform, etc.

-Stability: paʻa paʻa i ka wela lumi.

 

E hoʻohana:

- Hiki ke hoʻohana ʻia ka 2,5-Dichloronicotinic acid ma ke ʻano he waena i ka synthesis organik a hoʻohana nui ʻia i ka hoʻomākaukau ʻana i nā ʻano mea like ʻole a me nā pesticides.

-Hiki ke hoʻohana ʻia e like me ka ligand i loaʻa nā ion metala no ka synthesis o nā paʻakikī metala hoʻololi.

 

Hoʻomākaukau:

- Hiki ke hoʻomākaukau ʻia ka 2,5-Dichloronicotinic acid e ka chlorinating nicotinic acid. ʻO ke ʻano kikoʻī paha ka hoʻopili ʻana i ka waikawa nicotinic me ka thionyl chloride i kahi wela kiʻekiʻe, a ukali ʻia e ka crystallization hoʻomaha no ka loaʻa ʻana o ka huahana.

 

ʻIke palekana:

- 2,5-Dichloronicotinic acid ka loaʻa ʻana o ka huhū, no laila pono ʻoe e hoʻolohe i ka pale i ka wā o ka hana.

-ʻO ka meaʻawaʻawa a me ka pōʻino o ka 2,5-Dichloronicotinic acid e koi i ka noiʻi hohonu a me ka loiloi e hoʻoholo ai i kona palekana a me nā pōʻino. No laila, i ka hana ʻana a me ka hoʻohana ʻana, ʻōlelo ʻia e hahai i nā kaʻina hana palekana kūpono a lawe i nā hana palekana kūpono.
