2-Mercapto Pyrazine (CAS#38521-06-1)

Okwu mmalite

2-Mercaptopyrazine bụ ngwakọta organic nwere usoro kemịkalụ C4H4N2S. Ọ bụ kristal ọcha siri ike nke na-esi ísì ụtọ. Nke a bụ nkọwa nke ọdịdị, ojiji, nkwadebe na ozi nchekwa nke 2-Mercaptopyrazine:

Ọdịdị:

- Ọdịdị: White crystalline siri ike

-Arọ molekụla: 112.16g/mol

- ebe mgbaze: 80-82 ℃

-esi esi: ihe dị ka 260 ℃ (recomposition)

-Soluble: Soluble na acid, alkali, ethanol na ether, ubé soluble na mmiri.

Jiri:

-2-Mercaptopyrazine nwere ike iji dị ka ihe dị mkpa n'etiti na organic synthesis na ike ịrụ ọrụ dị mkpa na njikọ nke ọgwụ ọjọọ na pesticides.

- Enwere ike iji ya mee ihe iji kwadebe ihe eji esiji pyrazine, ndị na-ahụ maka ọgwụ na ọgwụ na-ejikọta ọnụ.

Ụzọ nkwadebe:

2-Mercaptopyrazine nwere ike ịmepụta:

1. Mmeghachi omume nke 2-bromopyrazine na sodium hydrogen sulfate na mmiri / ethanol iji nye 2-Mercaptopyrazine. Ọnọdụ mmeghachi omume na-adịkarị ka mmeghachi omume na-akpalite na okpomọkụ ụlọ.

2. 2-Mercaptopyrazine nwekwara ike nweta site na-emeghachi omume 2-chloropyrazine na thiol n'okpuru ọnọdụ alkaline.

Ozi nchekwa:

- 2-Mercaptopyrazine bụ ihe mgbakasị ahụ nke nwere ike ime ka mgbakasị ahụ na kọntaktị na akpụkpọ ahụ, anya ma ọ bụ site na iku ume nke ájá ya.

- Yiri akụrụngwa nchedo onwe onye dị ka mkpuchi mkpuchi kemịkalụ, ugogbe nchekwa na ihe mkpuchi mgbe ị na-eji 2-Mercaptopyrazine.

-Mgbe ị na-eji ogige a, biko gbaa mbọ hụ na ị na-arụ ọrụ na ebe ikuku na-ekpo ọkụ ka ị ghara ikuru uzuzu ya.

- Zere kọntaktị na oxidants na acid siri ike iji gbochie mmeghachi omume dị ize ndụ.

- Chekwaa 2-Mercaptopyrazine n'ime akpa ikuku, pụọ na ọkụ na isi ọkụ.
