2-Mercapto Methyl Pyrazine (CAS#59021-02-2)

Isingeniso

I-2-mercaptomethylpyrazine, eyaziwa nangokuthi i-2-mercaptopyrazine methane noma i-methazole, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2-mercaptomethylpyrazine:

Ikhwalithi:

I-2-mercaptomethylpyrazine iyikristale eqinile engenambala ukuya kokuphuzi enephunga elikhethekile le-thiol. Inoncibilika kahle ekamelweni lokushisa futhi iyancibilika emanzini, kuma-alcohol nezincibilikisi ze-ketone.

Sebenzisa:

I-2-mercaptomethylpyrazine inezinhlelo zokusebenza ezihlukahlukene. Ivame ukusetshenziswa njenge-ejenti yokunciphisa ku-organic synthesis futhi iyakwazi ukunciphisa izinhlanganisela ezifana ne-ketones, i-aldehydes, i-acids ne-alkyl halides. Ibuye isetshenziselwe ukuhlanganiswa kwama-ion complexes ensimbi, ama-catalysts for organic synthesis, kanye nezindawo eziphakathi kwamanye ama-fungicides kanye nezibulala-zinambuzane.

Indlela:

Indlela eyinhloko yokulungiselela i-2-mercaptomethylpyrazine ikhiqizwa ukusabela kwe-2-bromomethylpyrazine ne-sodium sulfide (noma i-ammonium sulfide). Izinyathelo eziqondile zimi kanje:

I-2-Bromomethylpyrazine isabela nge-sodium sulfide (noma i-ammonium sulfide) ukuze kukhiqizwe i-2-mercaptopyrazine methane kanye neminye imikhiqizo.

Ingxube yokusabela yahlanzwa futhi yacwebezelwa ukuze kutholwe i-2-mercaptomethylpyrazine.

Ulwazi Lokuphepha:

I-2-Mercaptomethylpyrazine iyinhlanganisela yezinto eziphilayo futhi kufanele isetshenziswe ngokuphepha. Kungase kube nomthelela ocasulayo emehlweni, esikhumbeni, nasendleleni yokuphefumula. Gqoka amagilavu ​​okuzivikela kanye nezibuko lapho usebenzisa, futhi uqinisekise indawo yokusebenza enomoya omuhle. Lapho uphatha amakhemikhali, landela izinqubo ezifanele zaselabhorethri ukuze uvimbele ukuchayeka kwesikhumba namehlo futhi ugweme ukuhogela umhwamuko wawo. Uma uthintana noma uhogela umoya, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.
