Hoʻolauna

ʻO 2-Aminopyrazine kahi mea hoʻohui kino. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana:

 

ʻAno maikaʻi:

ʻO ke ʻano: 2-aminopyrazine he paʻa kala kala ʻole.

Solubility: 2-aminopyrazine maikaʻi ka solubility i ka wai, a hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol a me ka chloroform.

Nā waiwai kemika: ʻO ka 2-aminopyrazine kahi mea alkaline e hana maʻalahi me nā waikawa e hana i nā paʻakai. Hiki iā ia ke hoʻokō i nā hopena kemika e like me nā hopena hoʻololi electrophilic.

 

E hoʻohana:

Mahiʻai: 2-Aminopyrazine hiki ke hoʻohana ʻia ma ke ʻano he pesticide e like me fungicides, herbicides, a me nā mea hoʻoponopono ulu.

 

Hanana:

Nui nā ʻano hoʻomākaukau no ka 2-aminopyrazine, a ʻo nā mea maʻamau e like me kēia:

Pyrazine a me ka ammonia hoʻomaʻamaʻa hoʻomākaukau: pyrazine a me ka amonia condensed a reacted i ke kiʻekiʻe wela, a laila hoʻomaʻemaʻe ma ka dehydration a me crystallization e loaa 2-aminopyrazine.

Ka hoʻomākaukauʻana i ka hydrogenation o pyrrolidone: pyrrolidone ua hydrogenated me ka amonia i mua o kahi catalyst e loaʻa ai ka 2-aminopyrazine.

 

ʻIke palekana:

ʻO ka 2-Aminopyrazine kahi hui kūlohelohe, a pono e uku ʻia i ka pale ahi a me ka pahū i ka wā e hoʻohana ai a mālama ai.

I ka wā e hui ai me 2-aminopyrazine, pono e pale ʻia ka hoʻopili pololei ʻana me ka ʻili a me ka inhalation o kāna kinoea. Pono e ʻaʻahu ʻia nā mea pale kūpono i ka wā e hoʻohana ai.

Inā loaʻa iā ʻoe ka ʻeha ma hope o ka ʻai ʻana a i ʻole ka pili ʻana i ka ʻili, e ʻimi koke i ka lāʻau lapaʻau a lawe mai i ka ipu a me ka lepili o ka hui.

I ka lawelawe ʻana i ka 2-aminopyrazine, pono e mālama ʻia nā hana palekana kūpono, a pono e hoʻolei pono ʻia ka ʻōpala.
