Hoʻolauna
ʻO 2-Ethyl-3-methylpyrazine kahi mea hoʻohui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:
ʻAno maikaʻi:
- Ke ʻano: Aia ka 2-ethyl-3-methylpyrazine i loko o ka wai kala ʻole a i ʻole ke ʻano crystalline paʻa.
- Solubility: He haʻahaʻa ka solubility i ka wai, akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik.
- Paʻa: He hui paʻa ia, akā pono e pale ʻia ka hoʻopili ʻana me nā oxidants ikaika a me nā waikawa ikaika.
E hoʻohana:
- ʻO 2-Ethyl-3-methylpyrazine ka mea hoʻohana maʻamau a hoʻohana ʻia ma ke ʻano he waena i ka synthesis kemika.
Hanana:
Hiki ke hoʻomākaukau ʻia ka 2-Ethyl-3-methylpyrazine e nā ʻano hana penei:
- Hoʻopili mua ʻia ka Ethyl bromide me ka pyrazine e hana i ka 2-ethylpyrazine ma lalo o nā kūlana alkaline.
- Ma hope iho, hoʻopili ʻia ka 2-ethylpyrazine me ka methyl bromide e hāʻawi i ka 2-ethyl-3-methylpyrazine hope loa.
ʻIke palekana:
- ʻO ka 2-Ethyl-3-methylpyrazine ka mea maʻamau i manaʻo ʻia he haʻahaʻa haʻahaʻa, akā pono e hahai ʻia nā kuʻina palekana kūpono.
- Hōʻalo i ka inhalation, pili me ka ʻili a me nā maka, a hoʻokomo i nā mea pale pilikino e like me nā mīkina lima, nā maka maka maka, a me nā pale maka.
- I ka mālama ʻana a me ka mālama ʻana, e hoʻokaʻawale iā ia mai nā kumu ignition a me nā mea oxidizing e pale aku i ka pilikia o ke ahi a me ka pahū.
- E nānā i nā palapala palekana kūpono a me nā pepa ʻikepili palekana i hāʻawi ʻia e ka mea hoʻolako no ka ʻike kikoʻī a pololei.
