Hoʻolauna
ʻO ka 2-Chloro-4-methylpyridine kahi hui kūlohelohe. Eia kekahi mau ʻike e pili ana i kāna mau waiwai, hoʻohana, hana hana, a me ka palekana.
ʻAno maikaʻi:
- Ke ʻano: 2-Chloro-4-methylpyridine he paʻa keʻokeʻo keʻokeʻo.
- Solubility: He haʻahaʻa kona hiki ke hoʻoheheʻe ʻia i loko o ka wai akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā waiʻona a me nā etera.
E hoʻohana:
- Hoʻohui kemika: Hoʻohana pinepine ʻia ka 2-chloro-4-methylpyridine ma ke ʻano he reagent a me ka waena i ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he chlorinated reagent i nā hopena kemika. No ka laʻana, hiki iā ia ke hana me nā ʻona e hana i nā eter, me nā aldehydes a me nā ketones e hana i nā pūhui imine, etc.
Hanana:
ʻElua mau ala maʻamau o ka hoʻomākaukau ʻana:
- Keʻano 1: Loaʻa ka 2-chloro-4-methylpyridine ma ka hana ʻana i ka 2-methylpyridine me ka hydrogen chloride.
- Ka Papa Hana 2: Loaʻa ka 2-chloro-4-methylpyridine ma ka hana ʻana i ka 2-methylpyridine me ke kinoea chlorine.
ʻIke palekana:
- He mea ʻawaʻawa ka 2-Chloro-4-methylpyridine a hiki ke hoʻonāukiuki i nā maka, ʻōnaehana hanu, a me ka ʻili. Pono e hoʻohana ʻia nā mea pale kūpono e like me nā mīkina lima, nā respirator a me nā maka aniani i ka wā e hoʻohana ai.
- Pono e mālama ʻia ma kahi maloʻo a maikaʻi-ventilated, ma kahi mamao aku i nā kumu ahi a me nā mea oxidants.
- E hahai i nā kaʻina hana palekana i ka wā e hoʻohana ai a pale i ka hui ʻana me nā kemika ʻē aʻe. Inā loaʻa ʻole ka ʻai ʻana, a i ʻole ka pili ʻana i ka ʻili, e ʻimi koke i ka lāʻau lapaʻau.
