Hoʻolauna
ʻO 2,4-Dichloropyridine kahi mea hoʻohui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2,4-dichloropyridine:
ʻAno maikaʻi:
- 2,4-Dichloropyridine he kala ʻole i nā kristal melemele a i ʻole wai.
- He ʻala ikaika kona.
- 2,4-Dichloropyridine ka haʻahaʻa solubility, insoluble i ka wai, a me ka maikai solubility i ka organic solvents.
E hoʻohana:
- Hiki ke hoʻohana ʻia ka 2,4-Dichloropyridine ma ke ʻano he reagent koʻikoʻi a me ka catalyst i ka synthesis organik.
- 2,4-Dichloropyridine ka mea maʻamau i hoʻohana ʻia ma ke ʻano he mea lapaʻau ʻili metala no ka wehe ʻana i nā kiʻi ʻoniʻoni a i ʻole ka degreasing.
Hanana:
- Loaʻa pinepine ʻia ke ʻano hoʻomākaukau o 2,4-dichloropyridine e ka hopena o 2,4-dichloropyran a me ka waikawa nitrous.
- Pono ka mahana kūpono a me ka manawa pane i ka wā o ka hopena, a me ka hoʻomalu ʻana ma lalo o nā kūlana acidic.
ʻIke palekana:
- ʻO 2,4-Dichloropyridine kahi hui kūlohelohe, a pono e mālama i ka hana palekana i ka wā e hoʻohana ai.
- ʻO ka hoʻolaha ʻana i ka 2,4-dichloropyridine hiki ke hoʻonāukiuki i ka ʻili, nā maka, a me ka ʻōnaehana hanu.
- E hoʻohana i nā lako pale pilikino kūpono e like me nā mīkina lima, nā maka aniani, a me nā mea hanu i ka wā e hoʻohana ai.
- Hōʻalo i ka hoʻopā ʻana i ka 2,4-dichloropyridine ma ka ʻili i ʻike ʻia a mālama i kahi wahi hana maikaʻi.
- I ka wā e hoʻolei ai i ka ʻōpala 2,4-dichloropyridine, pono e mālama ʻia nā lula hoʻokele kūloko.
