ʻO 2-acetylpyrazine kahi mea hoʻohui. He ʻono a me ka ʻala e like me ka palaoa kālua a i ʻole ka meaʻai i kālua ʻia. Eia ka wehewehe kikoʻī i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2-acetylpyrazine:
ʻAno maikaʻi:
- Ke ʻano: 2-acetylpyrazine he wai kala ʻole a melemele paha me kahi ʻala ʻokoʻa.
- Solubility: Hiki ke hoʻoheheʻe ʻia i loko o ka waiʻona, ketone a me ka ether solvents, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
E hoʻohana:
Hanana:
Nui nā ala e hoʻomākaukau ai i ka 2-acetylpyrazine:
- Loaʻa mai ka hopena o ka 1,4-diacetylbenzene a me ka hydrazine.
- Loaʻa ma ka catalytic reduction o 2-acetyl-3-methoxypyrazine a me ka hydrogen.
ʻIke palekana:
- Hōʻalo i ka pili ʻana me ka ʻili a me nā maka, a e hoʻohana i nā mīkina lima a me nā maka aniani ke hoʻohana.
- E hōʻalo i ka hoʻohu ʻana i kona mau mahu a e hana ma kahi wahi i hoʻoluʻu maikaʻi ʻia.
- I ka wā e mālama ai, pono e hoʻopaʻa paʻa ʻia, mai ke ahi a me nā mea ʻona.
- E hoʻokō i nā kaʻina hana palekana kūpono a me nā lula o ka wahi hana i ka wā e hoʻohana ai a mālama ʻia.
