Hoʻolauna
ʻO 3-Chloro-4-methylpyridine kahi mea hoʻohuihui. Penei kona mau waiwai.
1. ʻAno:3-chloro-4-methylpyridinehe wai waihoʻoluʻu ʻole i ka melemele māmā.
2. Māmā: 1.119 g/cm³
4. Solubility: 3-chloro-4-methylpyridine hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe ʻia a hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
ʻO nā hoʻohana nui o 3-chloro-4-methylpyridine e like me kēia:
1. Ka hoʻohuihui ʻana o nā metala hoʻololi: He koʻikoʻi koʻikoʻi ia i hoʻohana ʻia i ke kemika hoʻonohonoho ʻana no ka hoʻohui ʻana i nā amino alcohols, amino alkates, a me nā pūhui heterocyclic nitrogen.
2. Pesticide intermediates: Hiki ke hoʻohana ʻia ka 3-chloro-4-methylpyridine ma ke ʻano he waena i kekahi mau insecticides a me herbicides.
ʻO ke ʻano o ka hoʻomākaukau ʻana i ka 3-chloro-4-methylpyridine maʻamau e loaʻa i nā pae aʻe:
1. Nitroation reaction of pyridine: pyridine reacted with concentrated nitric acid and sulfuric acid e loaʻa ai ka 3-nitropyridine.
2. Hoʻoemi ka hopena: Hoʻopili ʻia ka 3-nitropyridine me ka nui o ka sulfoxide a me ka mea hoʻohaʻahaʻa (e like me ka pauka zinc) e loaʻa ai ka 3-aminopyridine.
3. Hoʻololi ʻana o ka chlorination: Hoʻopili ʻia ka 3-aminopyridine me ka thionyl chloride e loaʻa ai ka 3-chloro-4-methylpyridine.
ʻO ka ʻike palekana kūpono o 3-chloro-4-methylpyridine penei:
1. Hoʻonaʻauao: Loaʻa paha kahi hopena allergenic i kekahi mau heluna kanaka.
2. Hoʻohaunaele: Loaʻa paha kahi hopena hoʻonāukiuki i nā maka, ka ʻōnaehana hanu a me ka ʻili.
3. ʻAiʻona: He mea ʻawaʻawa ia i ke olakino kanaka a pono e hahai i nā kaʻina hana palekana kūpono.
4. Ka waiho ʻana: Pono e mālama ʻia i loko o kahi pahu airtight, ma kahi mamao aku i ka ʻāʻī a me nā oxidants, a ma kahi e pili ana me ka ea.
Ke hoʻohana ʻoe i ka 3-chloro-4-methylpyridine, e hahai i nā kuʻina palekana kūpono e like me ke komo ʻana i nā maka pale, nā mīkina lima a me nā lole pale, a e hōʻoia i ka hana ʻia ma kahi wahi e hoʻomaha maikaʻi ʻia. I ka hihia o ka hoʻopili ʻana a i ʻole ka inhalation, e ʻimi koke i ka lāʻau lapaʻau a hōʻike i ka Pepa ʻIkepili Palekana o ka huahana i kāu kauka.
