Hoʻolauna

2-ethoxy-3-isopropylpyrazine. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

 

ʻAno maikaʻi:

- Ke ʻano: 2-ethoxy-3-isopropylpyrazine he keʻokeʻo a ʻeleʻele melemele.

- Ka hoʻoheheʻe ʻia: ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol a me ka dimethyl sulfoxide.

 

E hoʻohana:

- Hoʻohana nui ʻia ka 2-ethoxy-3-isopropylpyrazine ma ke kahua o nā pesticides. Hiki ke hoʻohana ʻia ma ke ʻano he mea maka no nā pesticides a me nā mea hoʻomalu weed. ʻO kēia pūhui ka hana o ka pale ʻana i ka tyrosine ammonia-lyase mea kanu, a laila e hoʻopilikia ai i ka ulu ʻana o ka mea kanu.

- Ma waho aʻe o ke kahua o nā pesticides, hiki ke hoʻohana ʻia ka 2-ethoxy-3-isopropylpyrazine i ka synthesis o nā mea hoʻohui ʻē aʻe.

 

Hanana:

- Loaʻa pinepine ʻia ka 2-ethoxy-3-isopropylpyrazine e ka hopena o ka phenyl isocyanate me ka ethoxypropanol. Hoʻohana ka hopena i ka waikawa hydrochloric a i ʻole ka sodium hydroxide ma ke ʻano he catalyst e hoʻokō i ka hopena reflux i kahi lewa inert.

 

ʻIke palekana: He mea hoʻonāukiuki a pono e paleʻia mai ka piliʻana me kaʻili, nā maka, a me ka'āpana hanu.

- Pono e mālama pono i ka mālama ʻana a me ka mālama ʻana i ka 2-ethoxy-3-isopropylpyrazine, me ke komo ʻana i nā mīkina lima a me nā maka.

- I ka wā e hoʻolei ai i ka ʻōpala, e hoʻokō i nā lula kaiapuni kūpono.
