2-Amino Pyrazine (CAS#5049-61-6)

Mawu Oyamba

2-Aminopyrazine ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:

Ubwino:

Maonekedwe: 2-aminopyrazine ndi kristalo wopanda mtundu wolimba.

Kusungunuka: 2-aminopyrazine imakhala yabwino kusungunuka m'madzi, komanso imatha kusungunuka muzosungunulira monga ethanol ndi chloroform.

Chemical properties: 2-aminopyrazine ndi chinthu chamchere chomwe chimagwirizana mosavuta ndi zidulo kupanga mchere. Itha kuchitanso zinthu zina monga electrophilic substitution reaction.

Gwiritsani ntchito:

Ulimi: 2-Aminopyrazine itha kugwiritsidwa ntchito ngati mankhwala ophera tizilombo monga fungicides, herbicides, ndi zowongolera kukula kwa mbewu.

Njira:

Pali njira zambiri zokonzekera 2-aminopyrazine, ndipo zomwe zimagwiritsidwa ntchito kwambiri ndi izi:

Pyrazine ndi ammonia anachita kukonzekera: pyrazine ndi ammonia ndi condensed ndi anachita pa kutentha, ndiyeno kuyeretsedwa ndi kutaya madzi m'thupi ndi crystallization kupeza 2-aminopyrazine.

Kukonzekera kwa hydrogenation wa pyrrolidone: pyrrolidone ndi hydrogenated ndi ammonia pamaso pa chothandizira kupeza 2-aminopyrazine.

Zambiri Zachitetezo:

2-Aminopyrazine ndi organic pawiri, ndipo chidwi chiyenera kuperekedwa ku chitetezo cha moto ndi kuphulika pamene mukugwiritsa ntchito ndi kusunga.

Mukakumana ndi 2-aminopyrazine, kukhudzana mwachindunji ndi khungu ndi kupuma mpweya wake kuyenera kupewedwa. Zida zotetezera zoyenera ziyenera kuvalidwa panthawi yogwiritsira ntchito.

Ngati simukumva bwino mutameza kapena kukhudzana ndi khungu, funsani kuchipatala mwamsanga ndipo bweretsani chidebe ndi chizindikiro cha mankhwalawa.

Pogwira 2-aminopyrazine, njira zoyenera zotetezera ziyenera kutsatiridwa, ndipo zinyalala ziyenera kutayidwa bwino.
