Hoʻolauna
2,4-Dihydroxypyridine. Loaʻa iā ia nā waiwai penei:
ʻIke: 2,4-Dihydroxypyridine he paʻa keʻokeʻo keʻokeʻo.
Solubility: He mea hiki ke hoʻoheheʻe maikaʻi ʻia a hiki ke hoʻoheheʻe ʻia i ka wai a me nā ʻano mea hoʻoheheʻe organik.
Ligand: Ma keʻano he ligand no ka hoʻololiʻana i nā metala paʻakikī, hiki i ka 2,4-dihydroxypyridine ke hana i nā paʻa paʻa me nā metala, i hoʻohana nuiʻia i ka hoʻomākaukauʻana i nā catalysts a me nā mea koʻikoʻi synthesis organic reactions.
ʻO ka mea hoʻopaneʻe ʻino: Hoʻohana ʻia ia e like me kekahi o nā ʻāpana o nā mea hoʻopiʻi metala, hiki ke pale pono i nā ʻili metala mai ka pala.
ʻO ke ʻano o ka hoʻomākaukau ʻana o 2,4-dihydroxypyridine penei:
Hydrocyanic acid reaction method: 2,4-dichloropyridine ua hoʻopili ʻia me ka hydrocyanic acid e loaʻa ai ka 2,4-dihydroxypyridine.
ʻO ke ʻano hoʻohālikelike o ka hydroxylation: 2,4-dihydroxypyridine i hana ʻia e ka hopena o ka pyridine a me ka hydrogen peroxide ma lalo o kahi catalyst platinum.
ʻIke palekana: 2,4-Dihydroxypyridine he mea kemika a pono e hoʻohana me ka akahele:
ʻO ka ʻawaʻawa: 2,4-Dihydroxypyridine ka mea ʻawaʻawa i kekahi mau ʻano a hiki ke hoʻonāukiuki i ka maka a me ka ʻili ke hoʻopili ʻia. Pono e pale aku i ka pili pono a me ka inhalation o kona lepo.
Ka mālama ʻana: 2,4-Dihydroxypyridine pono e mālama ʻia i kahi maloʻo a me kahi maloʻo e pale aku i ka hoʻopili ʻana me nā oxidants a me nā waikawa ikaika. I ka wā o ka mālama ʻana, pono e mālama ʻia ka mālama ʻana i ka makū i mea e pale ai i ka pōʻino ma muli o ka wai.
ʻO ka hoʻolei ʻana i ka ʻōpala: ʻO ka hoʻolei kūpono o ka ʻōpala, pono e mālama i nā kānāwai kaiapuni a me nā lula, e pale aku i ka haumia o ke kaiapuni.
I ka wā e hoʻohana ai i ka 2,4-dihydroxypyridine, pono e hahai ʻia nā kaʻina hana palekana kūpono a me nā ʻano pale pilikino, e like me ke komo ʻana i nā mīkina lima a me nā maka aniani.
