Intshayelelo

I-2-Aminopyrazine yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:

 

Umgangatho:

Imbonakalo: I-2-aminopyrazine yinto eqinileyo yekristale engenambala.

Ukunyibilika: I-2-aminopyrazine ine-solubility efanelekileyo emanzini, kwaye inokunyibilika kwii-solvents eziphilayo ezifana ne-ethanol kunye ne-chloroform.

Iimpawu zemichiza: I-2-aminopyrazine yinto yealkaline esebenza ngokulula kunye ne-asidi ukwenza iityuwa. Isenokwenza ukusabela kweekhemikhali ezifana neempendulo ze-electrophilic substitution.

 

Sebenzisa:

Ezolimo: I-2-Aminopyrazine ingasetyenziswa njengesithako sokubulala izitshabalalisi ezifana nemichiza yokungunda, imichiza yokutshabalalisa ukhula, kunye nezilawuli zokukhula kwezityalo.

 

Indlela:

Zininzi iindlela zokulungiselela i-2-aminopyrazine, kwaye ezo zisetyenziswa ngokuqhelekileyo zezi zilandelayo:

I-Pyrazine kunye nokulungiswa kokuphendula kwe-ammonia: i-pyrazine kunye ne-ammonia iyancipha kwaye iphendule kwiqondo lokushisa eliphezulu, kwaye ihlanjululwe ngokuchithwa kwamanzi kunye ne-crystallization ukufumana i-2-aminopyrazine.

Ukulungiswa kwe-hydrogenation ye-pyrrolidone: i-pyrrolidone i-hydrogenated ne-ammonia phambi kwe-catalyst ukufumana i-2-aminopyrazine.

 

Ulwazi ngoKhuseleko:

I-2-Aminopyrazine yi-organic compound, kwaye ingqalelo kufuneka ihlawulwe kumlilo kunye nokukhusela ukuqhuma xa usebenzisa kwaye ugcina.

Xa udibana ne-2-aminopyrazine, ukudibanisa ngokuthe ngqo kwesikhumba kunye nokuphefumla igesi yayo kufuneka kugwenywe. Izixhobo ezifanelekileyo zokukhusela kufuneka zinxitywe ngexesha lokusetyenziswa.

Ukuba ufumana ukungonwabi emva kokuginya okanye ukudibana kwesikhumba, funa unyango ngokukhawuleza kwaye uzise isitya kunye neleyibhile yekhompawundi.

Xa uphatha i-2-aminopyrazine, iindlela ezifanelekileyo zokukhusela kufuneka zithotyelwe, kwaye inkunkuma kufuneka ilahlwe ngokufanelekileyo.
