Hoʻolauna

ʻO ka 2-Cyano-3,5-dichloropyridine he mea hoʻohuihui mea ola me ke ʻano kemika C6H2Cl2N2. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.

 

ʻAno:

ʻO 2-Cyano-3,5-dichloropyridine he paʻa melemele ʻole a ʻeleʻele paha. He haʻahaʻa volatility ma ka lumi wela. He haʻahaʻa ka solubility i ka wai a me ka solubility kiʻekiʻe i nā mea hoʻoheheʻe organik e like me ka ethanol a me ka dimethylformamide.

 

E hoʻohana:

ʻO 2-Cyano-3,5-dichloropyridine ka nui o nā noi i ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he waena no ka synthesis o nā pūhui organik like ʻole (e like me nā lāʻau lapaʻau, nā mea ʻulaʻula a me nā pesticides). Eia kekahi, hiki ke hoʻohana ʻia ma ke ʻano he mea i ka noiʻi ʻana i nā diodes māmā māmā (OLED) a me nā hōʻike aniani wai.

 

Kaʻina hoʻomākaukau:

Hiki ke hoʻomākaukau ʻia ka 2-Cyano-3,5-dichloropyridine me ka hoʻohana ʻana i nā ʻano hana synthetic. ʻO ke ʻano hana synthetic maʻamau ka hana ʻana i ka pūhui pyridine pili me ka cyanide, a ukali ʻia e ka chlorination e loaʻa ai ka huahana.

 

ʻIke palekana:

Hiki ke noʻonoʻo ʻia ʻo 2-Cyano-3,5-dichloropyridine he mea pōʻino ma lalo o nā kūlana maʻamau. He mea hoʻonāukiuki paha i ka ʻōpū hanu, nā maka a me ka ʻili. I ka hoʻohana ʻana, pono e hana i nā mea pale kūpono, e like me ke komo ʻana i nā mīkina lima a me nā aniani. E hōʻalo i ka hoʻopili ʻana me nā mea oxidizing a me nā ʻakika ikaika i ka wā mālama a mālama ʻia. Inā ʻike ʻia a inhaled paha, e ʻimi koke i ka lāʻau lapaʻau.
