Nhanganyaya

2-Aminopyrazine inhengo yemuviri. Iyi inotevera sumo kune hunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:

 

Hunhu:

Kuonekwa: 2-aminopyrazine ikristaro isina ruvara yakasimba.

Solubility: 2-aminopyrazine ine yakanaka solubility mumvura, uye inogona zvakare kunyungudika muorganic solvents senge ethanol uye chloroform.

Chemical properties: 2-aminopyrazine chinhu chine alkaline chinopindirana zviri nyore nemaasidhi kuita munyu. Inogona zvakare kuita kemikari kuita senge electrophilic substitution reactions.

 

Shandisa:

Zvekurima: 2-Aminopyrazine inogona kushandiswa semushonga wezvipembenene senge fungicides, herbicides, uye zvinomera zvinokura.

 

Nzira:

Kune nzira dzakawanda dzekugadzirira 2-aminopyrazine, uye dzinowanzo shandiswa ndedzinotevera:

Pyrazine uye ammonia maitiro ekugadzirira: pyrazine uye ammonia zvinoputirwa uye zvinogadziriswa pakupisa kwepamusoro, uye zvino kunatswa nekushaya mvura uye crystallization kuwana 2-aminopyrazine.

Kugadzirira kwehydrogenation yepyrrolidone: pyrrolidone inonzi hydrogenated neammonia muhupo hwekugadzirisa kuwana 2-aminopyrazine.

 

Zvekuchengetedza

2-Aminopyrazine musanganiswa weorganic, uye kutarisisa kunofanirwa kubhadharwa kune moto uye kudzivirira kuputika paunenge uchishandisa nekuchengetedza.

Paunosangana ne2-aminopyrazine, kusangana kwakananga neganda uye kufema kwegasi rayo kunofanira kudzivirirwa. Magiya ekudzivirira akakodzera anofanirwa kupfekwa panguva yekushandiswa.

Kana ukanzwa kusagadzikana mushure mekumedza kana kubata ganda, tsvaga kurapwa nekukurumidza uye uuye nemudziyo uye chinyorwa chekomboni.

Paunenge uchibata 2-aminopyrazine, maitiro akakodzera ekuchengetedza anofanirwa kutevedzerwa, uye tsvina inofanira kuraswa zvakanaka.
