Hoʻolauna
ʻO ka 2-mercapto-3-methylpyrimidine kahi hui kūlohelohe.
ʻO nā waiwai maʻamau o kēia hui pū kekahi:
- Nā hiʻohiʻona: nā kala kala ʻole a melemele paha
- Hiki ke hoʻoheheʻe ʻia: hiki ke hoʻoheheʻe ʻia i loko o ka waiʻona a me nā solvents ether, hiki ʻole ke hoʻoheheʻe ʻia i ka wai
Loaʻa i ka 2-furfurthio-3-methylpyrazine ka nui o nā noi, me:
- Chemical synthesis: Hiki ke hoʻohana ʻia ma ke ʻano he reagent koʻikoʻi, waena a me ka catalyst, a komo i ka synthesis o nā pūhui organik.
ʻO ke ala no ka hoʻomākaukau ʻana i ka 2-furfurthio-3-methylpyrazine ka mea maʻamau i kēia mau hana:
ʻO ka distillation o nā pūhui ocrytal a me methyl e hoʻomākaukau ai i ka 1-methylpyrazine.
Hoʻopili ʻia ka 1-methylpyrazine me ka thiol e hana i ka 2-furfurylthio-3-methylpyrazine.
- Hiki ke hoʻonāukiuki i ka maka, ka ʻili, a me ka ʻōpū hanu, a pono e hoʻohana ʻia nā mea pale kūpono e like me nā maka aniani, nā mīkina lima, a me nā masks kinoea i ka wā e hana ai.
- Hōʻalo i ka hoʻohu ʻana i ka lepo a i ʻole ke kinoea a mālama i kahi kaiaola hoʻonaʻauao maikaʻi.
- I ka lawelawe ʻana a mālama ʻana paha, pono e mālama ʻia e pale aku i ka pane ʻana me nā oxidants ikaika a me nā ʻakika ikaika, a pale i ka ʻā a me nā wela kiʻekiʻe.
