Selelekela
2-Mercaptopyrazine ke motsoako oa tlhaho o nang le foromo ea lik'hemik'hale C4H4N2S. Ke 'mala o mosoeu oa kristale o monko o monate. E latelang ke tlhaloso ea mofuta, tšebeliso, tokiso le tlhaiso-leseling ea polokeho ea 2-Mercaptopyrazine:
Tlhaho:
-Ponahalo: E tiileng ka kristale e tšoeu
- Boima ba limolek'hule: 112.16g / mol
- sebaka se qhibilihang: 80-82 ℃
- Sebaka se belang: hoo e ka bang 260 ℃ (ho bola)
-Soluble: E qhibiliha ka asiti, alkali, ethanol le ether, e qhibiliha hanyane ka metsing.
Sebelisa:
- 2-Mercaptopyrazine e ka sebelisoa e le setsi sa bohlokoa sa lipakeng tsa organic synthesis 'me e ka bapala karolo ea bohlokoa ho kopantsoeng ha lithethefatsi le chefo e bolaeang likokoanyana.
-E ka sebelisoa ho lokisa lidae tsa pyrazine, li-intermediate tsa meriana le metsoako ea ho hokahanya.
Mokhoa oa ho itokisa:
2-Mercaptopyrazine e ka etsoa:
1. Karabelo ea 2-bromopyrazine e nang le sodium hydrogen sulfate metsing / ethanol ho fana ka 2-Mercaptopyrazine. Maemo a karabelo ka kakaretso a joalo hoo karabelo e tsosoang mocheso oa kamore.
2. 2-Mercaptopyrazine e ka boela ea fumanoa ka ho arabela 2-chloropyrazine le thiol tlas'a maemo a alkaline.
Lintlha tsa Tšireletseho:
- 2-Mercaptopyrazine ke motsoako o halefisang o ka bakang ho halefa ha ho kopana le letlalo, mahlo kapa ka ho hema lerōle la eona.
-Apara lisebelisoa tsa ho itšireletsa tse kang li-gloves tse sireletsang lik'hemik'hale, likhalase tsa tšireletso le limaske tse sireletsang ha u tšoara 2-Mercaptopyrazine.
-Ha o sebelisa motsoako ona, ka kopo etsa bonnete ba hore o sebetsa sebakeng se nang le moea o motle ho qoba ho hema lerōle la lona.
- Qoba ho kopana le li-oxidants le li-acid tse matla ho thibela liketso tse kotsi.
- Boloka 2-Mercaptopyrazine ka har'a setshelo se sa keneng moea, hole le mocheso le mehloli ea mollo.
