Hoʻolauna
ʻO 2-Chloro-4-methyl-3-nitropyridine kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:
Nā Waiwai: 2-Chloro-4-methyl-3-nitropyridine he kala ʻole i ka paʻa melemele māmā me kahi ʻala ʻala. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai a hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol a me ka dimethylformamide. He mea make loa.
Hoʻohana: 2-chloro-4-methyl-3-nitropyridine i hoʻohana nui ʻia ma ke ʻano he mea koʻikoʻi koʻikoʻi a me ka synthetic raw material i ka synthesis organik. Hiki ke hoʻohana ʻia i ka hoʻomākaukau ʻana i nā paʻakikī metala a me nā catalysts.
Ke ala hoʻomākaukau: Hoʻomaka maʻamau ka hoʻomākaukau ʻana o 2-chloro-4-methyl-3-nitropyridine me 2-chloro-4-methylpyridine. ʻO ka mua, ua hoʻopili ʻia ka 2-chloro-4-methylpyridine me ka waikawa nitric concentrated, a laila ua crystallized a hoʻomaʻemaʻe ʻia ka huahana no ka loaʻa ʻana o 2-chloro-4-methyl-3-nitropyridine.
ʻIke palekana: ʻO 2-Chloro-4-methyl-3-nitropyridine he mea ʻawaʻawa e hiki ke hōʻeha i ke olakino inā e ʻike ʻia a i ʻole ʻia i loko o kāna mau mahu, pauka, a i ʻole nā mea hoʻonā. He mea hoʻonāukiuki a hoʻonāwaliwali a pono e paleʻia mai ka piliʻana me kaʻili, nā maka, a me ka'āpana hanu. Pono e mālama ʻia nā hana palekana kūpono i ka wā e lawelawe ai a mālama ʻia paha, e like me ke komo ʻana i nā mea pale kūpono (e laʻa, nā mīkina lima, nā aniani, a me nā maka. Ke hoʻohana ʻia, e hōʻoia i kahi kaiapuni maikaʻi a pale i ka hoʻopili ʻana me nā mea hiki ke ahi. Pono e hoʻolei ʻia nā ʻōpala e pili ana i ka 2-chloro-4-methyl-3-nitropyridine e like me nā kānāwai kūloko. Ke hoʻohana a lawelawe ʻana paha i kēia pūhui, pono e hahai pono i nā kaʻina hana palekana kūpono a me nā alakaʻi.
