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

Isingeniso

I-2-Aminopyrazine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:

Ikhwalithi:

Ukubukeka: I-2-aminopyrazine iyikristalu eqinile engenambala.

Ukunyibilika: I-2-aminopyrazine inokunyibilika okuhle emanzini, futhi ingancibilika kuzincibilikisi zemvelo ezifana ne-ethanol ne-chloroform.

Izakhiwo zamakhemikhali: I-2-aminopyrazine iyi-alkaline ehlangana kalula nama-asidi ukwenza usawoti. Ingakwazi futhi ukwenza ukusabela kwamakhemikhali njengokusabela kwe-electrophilic substitution.

Sebenzisa:

Ezolimo: I-2-Aminopyrazine ingasetshenziswa njengesithako sesibulala-zinambuzane njengama-fungicides, ama-herbicides, kanye nezilawuli zokukhula kwezitshalo.

Indlela:

Ziningi izindlela zokulungiselela i-2-aminopyrazine, futhi ezivame ukusetshenziswa yilezi ezilandelayo:

I-Pyrazine kanye nokulungiswa kokusabela kwe-ammonia: i-pyrazine ne-ammonia iyafinyezwa futhi isabela ekushiseni okuphezulu, bese ihlanzwa ngokuphela kwamanzi kanye ne-crystallization ukuze ithole i-2-aminopyrazine.

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

Ulwazi Lokuphepha:

I-2-Aminopyrazine iyinhlanganisela yezinto eziphilayo, futhi kufanele kuqashelwe ekuvikelweni komlilo nokuqhuma lapho kusetshenziswa futhi kugcinwa.

Lapho uhlangana ne-2-aminopyrazine, ukuthintana ngqo nesikhumba kanye nokuhogela igesi yayo kufanele kugwenywe. Izimpahla zokuzivikela ezifanele zidinga ukugqokwa ngesikhathi sokusetshenziswa.

Uma uzwa ukungakhululeki ngemva kokugwinya noma ukuthinta isikhumba, funa usizo lwezokwelapha ngokushesha futhi ulethe isitsha kanye nelebula lenhlanganisela.

Lapho uphatha i-2-aminopyrazine, izinqubo zokuphepha ezifanele kufanele zilandelwe, futhi udoti kufanele ulahlwe ngendlela efanele.
