Hoʻolauna
ʻO ka 2-Mercaptopyrazine kahi mea hoʻohui kino me ke ʻano kemika C4H4N2S. He paʻa keʻokeʻo keʻokeʻo me ka ʻala ʻala. Eia ka wehewehe ʻana o ke ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana o 2-Mercaptopyrazine:
ʻAno:
-Ke ʻano: Paʻa keʻokeʻo keʻokeʻo
-Molecular kaumaha: 112.16g/mol
-kahi hoʻoheheʻe: 80-82 ℃
-Pila paila: ma kahi o 260 ℃ (decomposition)
-Soluble: Hiki ke hoʻoheheʻe ʻia i ka waika, alkali, ethanol a me ka etera, hiki ke hoʻoheheʻe iki i ka wai.
E hoʻohana:
- Hiki ke hoʻohana ʻia ʻo 2-Mercaptopyrazine ma ke ʻano he koʻikoʻi koʻikoʻi i ka synthesis organik a hiki ke pāʻani i kahi kuleana nui i ka synthesis o nā lāʻau lapaʻau a me nā pesticides.
-Hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā dyes pyrazine, pharmaceutical intermediates a me coordination compound.
Kaʻina hoʻomākaukau:
2-Mercaptopyrazine hiki ke synthesized:
1. ʻO ka hopena o 2-bromopyrazine me ka sodium hydrogen sulfate i ka wai / ethanol e hāʻawi iā 2-Mercaptopyrazine. ʻO ke ʻano o ka pane ʻana ma ke ʻano maʻamau e hoʻoulu ʻia ka hopena ma ka lumi wela.
2. Hiki ke loaʻa ka 2-Mercaptopyrazine ma ka hana ʻana i ka 2-chloropyrazine me ka thiol ma lalo o nā kūlana alkaline.
ʻIke palekana:
- ʻO 2-Mercaptopyrazine he mea hoʻonāukiuki i hiki ke hoʻonāukiuki i ka pili ʻana me ka ʻili, nā maka a i ʻole ka inhalation o kona lepo.
-E hoʻohana i nā mea pale pilikino e like me nā mīkina lima pale kemika, nā aniani palekana a me nā pale pale i ka wā e lawelawe ai i ka 2-Mercaptopyrazine.
-I ka hoʻohana ʻana i kēia pūhui, e ʻoluʻolu e hana ma kahi wahi e hoʻoheheʻe maikaʻi ʻia e pale aku ai i kona lepo.
-E hōʻalo i ka hoʻopili ʻana me nā mea oxidants a me nā ʻakika ikaika e pale i nā hopena ʻino.
-E kūʻai i ka 2-Mercaptopyrazine i loko o kahi pahu hau, ma kahi mamao mai nā kumu wela a me ke ahi.
