Hoʻolauna

ʻO ka 2,6-Dimethylpyrazine kahi hui kūlohelohe.

 

ʻAno maikaʻi:

- ʻO 2,6-Dimethylpyrazine kahi pauka paʻa keʻokeʻo a i ʻole melemele māmā i ke kala.

- He hiki ke hoʻoheheʻe ʻia i loko o ka wai a me nā mea hoʻoheheʻe organik.

- Paʻa i ka ea, akā hiki ke decompose i nā wela kiʻekiʻe.

 

E hoʻohana:

- Hoʻohana nui ʻia ka 2,6-Dimethylpyrazine i nā ʻano kemika a me nā ʻenehana ʻenehana.

- Hiki ke hoʻohana ʻia ma ke ʻano he reagent kemika i ka noiʻi ʻepekema i ka synthesis organik a me ke kemika analytical.

- Hiki ke hoʻohana ʻia ma ke ʻano he catalyst no nā polymers.

 

Hanana:

- 2,6-Dimethylpyrazine hiki ke synthesized e nā ʻano hana like ʻole, ka mea maʻamau i hoʻomākaukau ʻia e ka cyclization o styrene a me methyl methacrylate.

 

ʻIke palekana:

- 2,6-Dimethylpyrazine kahi hui palekana ma lalo o nā kūlana maʻamau o ka hoʻohana.

- He mea hoʻonāukiuki i ka ʻili, nā maka, a me ka ʻōpū hanu a pono e pale pono ʻia i ka wā e hoʻohana ai, mālama ʻia a mālama ʻia.

- Hōʻalo i ka ʻai ʻana, pili me ka ʻili a me ka inhalation o ka lepo i ka wā o ka hana.

- Inā loaʻa ka pilikia a i ʻole ka inhalation, holoi koke i ka wahi i hoʻopilikia ʻia me ka wai maʻemaʻe a ʻimi koke i ka lāʻau lapaʻau. I ka pilikia, e ʻimi i ke kōkua lapaʻau ʻoihana.

 

He ʻike kumu wale nō ka mea i luna, no ka ʻike kikoʻī a me ka hoʻohana kikoʻī, e ʻoluʻolu e nānā i ka palapala kemika kūpono a i ʻole e nīnau i kahi loea.
