Intshayelelo
I-2-Methylthiopyrazine yi-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-2-methylthiopyrazine:
Umgangatho:
- I-2-Methylthiopyrazine ayinambala ukuya kwikristale ekhanyayo ephuzi okanye i-crystalline powder enevumba lesulfure elibuthathaka.
- I-alkaline xa inyibilika emanzini kwaye inokuchithwa kuzo zombini izisombululo ze-acidic kunye ne-alkaline.
- Xa ishushu okanye ivutha, i-2-methylthiopyrazine ikhupha iigesi ezinobuthi.
Sebenzisa:
- I-2-Methylthiopyrazine isetyenziswa ngokubanzi kwi-chemical synthesis njenge-catalyst okanye i-ligand ye-organic synthesis reactions.
Indlela:
- Ukulungiswa kwe-2-methylthiopyrazine ngokuqhelekileyo kufumaneka ngokuphendula kwe-sulfide kunye ne-2-chloropyridine. Isinyathelo esithile kukusabela i-2-chloropyridine kunye ne-sodium sulfide kwi-solvent ye-organic ukuze ufumane imveliso ye-2-methylthiopyrazine.
Ulwazi ngoKhuseleko:
- I-2-Methylthiopyrazine i-compound enetyhefu kwaye kufuneka igwenywe kwi-inhalation, ukungeniswa, okanye ukudibanisa nesikhumba kunye namehlo.
- Izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu, iindondo, iigawuni kufuneka zinxitywe ngexesha lokusetyenziswa okanye ukulungiselela.
- Kufuneka isetyenziswe kwindawo engena umoya ukuze kuthintelwe ukuxinwa komphunga okungaphezulu komda wokhuseleko.
- Xa ugcina, kufuneka igcinwe itywinwe ngokuqinileyo, kude nomlilo kunye ne-oxidants.
- Kwimeko yoqhagamshelwano ngengozi okanye ukungeniswa, funa unyango ngokukhawuleza.
