Nhanganyaya

2-Mercaptopyrazine inhengo yeorganic ine kemikari formula C4H4N2S. I crystalline yakachena yakasimba uye inonhuwa. Inotevera rondedzero yechimiro, kushandiswa, kugadzirira uye chengetedzo ruzivo rwe2-Mercaptopyrazine:

Zvakasikwa:

-Kuonekwa: White crystalline yakasimba

-Molecular uremu: 112.16g/mol

-kunyungudika nzvimbo: 80-82 ℃

-Kubikira nzvimbo: inenge 260 ℃ (kuora)

-Soluble: Soluble mu acid, alkali, ethanol uye ether, inonyungudika zvishoma mumvura.

Shandisa:

- 2-Mercaptopyrazine inogona kushandiswa seyakakosha yepakati mune organic synthesis uye inogona kuita basa rakakosha mukuumbwa kwemishonga nemishonga yezvipembenene.

-Inogona kushandiswa kugadzira pyrazine dhayi, mishonga yepakati uye kurongeka kwemakemikari.

Kugadzirira nzira:

2-Mercaptopyrazine inogona kugadzirwa:

1. Kuita kwe2-bromopyrazine ne sodium hydrogen sulfate mumvura / ethanol kupa 2-Mercaptopyrazine. Mamiriro ekuita anowanzo kuti maitiro anomutswa patembiricha yekamuri.

2. 2-Mercaptopyrazine inogonawo kuwanikwa kuburikidza nekuita 2-chloropyrazine ne thiol pasi pemamiriro e-alkaline.

Zvekuchengetedza

- 2-Mercaptopyrazine chinhu chinogumbura chinogona kukonzera kutsamwa mukubata neganda, maziso kana nekufema kweguruva rayo.

-Pfeka zvidziviriro zvekuzvidzivirira zvakadai semakemikari ekudzivirira magirafu, magirazi ekuchengetedza uye masikisi ekudzivirira paunenge uchibata 2-Mercaptopyrazine.

-Paunoshandisa komputa iyi, ndapota ita shuwa kuti unoshanda munzvimbo ine mhepo inofefetera kuti usafemedze guruva rayo.

-Dzivisa kusangana neoxidants uye yakasimba acids kudzivirira kuita zvine njodzi.

-Chengetedza 2-Mercaptopyrazine mumudziyo usina mhepo, kure nekupisa uye moto.
