Hoʻolauna

ʻO 2,5-Dichloro-3-nitropyridine kahi mea hoʻohui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:

 

ʻAno maikaʻi:

- Ke ʻano: 2,5-Dichloro-3-nitropyridine he aniani ʻeleʻele ʻeleʻele.

- Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, dimethyl ether a me ka chloroform, akā liʻiliʻi i ka wai.

- Paʻa: Paʻa ka pūhui ma ka lumi wela, akā pahū i nā wela kiʻekiʻe a i ʻole e pili ana me nā mea hoʻoheheʻe ikaika.

 

E hoʻohana:

- Pesticides: Hiki ke hoʻohana ʻia ma ke ʻano he insecticide a loaʻa ka hopena hoʻomalu maikaʻi i kekahi mau pest.

 

Hanana:

ʻO ke ʻano hana synthesis o 2,5-dichloro-3-nitropyridine ka mea maʻamau i ka hopena nitrification a me ka hopena chlorination. I waena o lākou, ʻo ke ʻano synthesis kuʻuna ʻo ia ka nitrate 2,5-dichloropyridine me ka waikawa nitric i mua o ka waikawa sulfuric. ʻO kekahi ala ʻē aʻe e hana i ka 2-nitro-5-chloropyridine me ka bromide keleawe ʻakika e hana i ka 2,5-dichloro-3-nitropyridine.

 

ʻIke palekana:

- ʻO 2,5-Dichloro-3-nitropyridine kahi mea hoʻohuihui e pono e mālama ʻia me ka mālama ʻana i mea e pale aku ai i ka pili ʻana me ka ʻili, nā maka, a me ka ʻōnaehana hanu.

- E hoʻohana i nā mea pale kūpono, e like me nā pale maka, nā mīkina lima, a me nā pale alo, ke hana.

- I ka wā o ka hana ʻana, e pale i ka hoʻohu ʻana i nā kinoea, ka noe a i ʻole ka mahu a mālama i ka ea maikaʻi.

- Inā pili me ka ʻili a i ʻole nā ​​maka, holoi koke me ka wai nui a nīnau i ke kauka.

- I ka wā e mālama ai, pono e mālama ʻia ka 2,5-dichloro-3-nitropyridine i kahi maloʻo, ʻoluʻolu, maikaʻi-ventilated, kahi mamao mai ka ʻāʻī a me nā oxidants.
