Hoʻolauna
ʻO 2-Methoxypyrimidine kahi mea hoʻohui. He paʻa keʻokeʻo keʻokeʻo me kahi ʻala ʻokoʻa. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2-methoxypyrazine:
ʻAno maikaʻi:
- Ke ʻano: Paʻa keʻokeʻo keʻokeʻo
- Hiki ke hoʻoheheʻe ʻia: hiki ke hoʻoheheʻe ʻia i loko o ka waiʻona, nā etera a me nā mea hoʻoheheʻe ester, hiki ke hoʻoheheʻe ʻia i ka wai
E hoʻohana:
- Hiki ke hoʻohana ʻia ʻo 2-Methoxypyrazine i ka ʻoihana dye e synthesize i nā mea hoʻonaninani.
Hanana:
- Loaʻa pinepine ʻia ka 2-Methoxypyrazine e ka hopena o 2-hydroxypyrazine a me ka methanol. Hoʻopili ʻia ʻo 2-Hydroxypyrazine me ka sodium formate a i ʻole ka sodium carbonate e hana i ka paʻakai sodium pili, a laila hoʻohui ʻia ka methanol keu e hoʻokō i ka hopena i ka mahana kūpono a me ka manawa pane. Ua loaʻa ka huahana 2-methoxypyrazine ma o ka hoʻomaʻamaʻa acidic, crystallization, maloʻo a me nā pae ʻē aʻe.
ʻIke palekana:
- 2-Methoxypyrazine mea hoʻonāukiuki a pono e pale ʻia mai ka hoʻopili ʻana me ka ʻili a me nā maka.
- E mālama pono i ka wā e hoʻohana ai, e like me ka pale ʻana i ka maka a me ka respirator.
- Hōʻalo i ka hanu ʻana, ka ʻai ʻana, a i ʻole ka hoʻopili ʻana me ka lepo, nā kinoea, a i ʻole nā hopena o ka hui.
- E hōʻoia i nā kūlana ea maikaʻi i ka wā o ka hana.
- E kūʻai i ka 2-methoxypyrazine ma kahi maloʻo, ʻoluʻolu a me ka makani maikaʻi mai ke ahi a me nā mea ʻona.
