Hoʻolauna

ʻO 2-Ethyl-5-methylpyrazine kahi mea hoʻohui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka pūhui:

 

ʻAno maikaʻi:

ʻO 2-Ethyl-5-methylpyrazine kahi paʻa keʻokeʻo keʻokeʻo i hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol a me ka etera.

 

E hoʻohana:

 

Hanana:

ʻO ka hoʻomākaukau ʻana o 2-ethyl-5-methylpyrazine e hana mau ʻia e nā ʻano kemika. ʻO ke ʻano hana synthesis maʻamau ka hana ʻana i ka nui kūpono o ka methyl acetone a me ka ethylenediamine ma lalo o nā kūlana hopena kūpono e loaʻa ai ka huahana i koho ʻia.

 

ʻIke palekana:

ʻO ka 2-Ethyl-5-methylpyrazine he haʻahaʻa haʻahaʻa akā pono e hahai ʻia no ka mālama pono ʻana. Ke pili me ka ʻili a me nā maka, holoi koke me ka wai. I ka wā o ka hana, e ho'āʻo e pale i ka inhaling i kona mahu, inā he inhalation, e ʻoluʻolu e noho mamao mai ke kumu kumu i ka ea hou i ka manawa. I ka mālama ʻana, pono e pale aku i ka hoʻopili ʻana me nā mea e like me nā oxidants a me nā waikawa ikaika e pale aku i nā kūlana pōʻino. E ʻoluʻolu e heluhelu i ka pepa ʻikepili palekana a me nā ʻōlelo aʻoaʻo hana no ka hui ma mua o ka hoʻomaka ʻana i kekahi kaʻina hana.
