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

Mawu Oyamba

2-Mercaptopyrazine ndi organic pawiri ndi mankhwala formula C4H4N2S. Ndi kristalo woyera wolimba ndi fungo lamphamvu. Zotsatirazi ndizofotokozera zamtundu, kugwiritsa ntchito, kukonzekera ndi chitetezo cha 2-Mercaptopyrazine:

Chilengedwe:

-Maonekedwe: Mwala wonyezimira woyera

-Kulemera kwa mamolekyu: 112.16g/mol

-malo osungunuka: 80-82 ℃

- Malo otentha: pafupifupi 260 ℃ (kuwola)

-Kusungunuka: Kusungunuka mu asidi, alkali, ethanol ndi ether, kusungunuka pang'ono m'madzi.

Gwiritsani ntchito:

- 2-Mercaptopyrazine ingagwiritsidwe ntchito ngati yofunika kwambiri pakati pa kaphatikizidwe ka organic ndipo ikhoza kukhala ndi gawo lofunikira pakupanga mankhwala ndi mankhwala ophera tizilombo.

-Itha kugwiritsidwa ntchito popanga utoto wa pyrazine, ma pharmaceutical intermediates ndi ma coordination compounds.

Njira Yokonzekera:

2-Mercaptopyrazine imatha kupangidwa:

1. Kuchita kwa 2-bromopyrazine ndi sodium hydrogen sulfate m'madzi/ethanol kupereka 2-Mercaptopyrazine. Zomwe zimachitika nthawi zambiri zimakhala kuti zomwe zimakhudzidwa zimatenthedwa firiji.

2. 2-Mercaptopyrazine imathanso kupezeka pochita 2-chloropyrazine ndi thiol pansi pamikhalidwe yamchere.

Zambiri Zachitetezo:

- 2-Mercaptopyrazine ndi mankhwala owopsa omwe angayambitse kupsa mtima pokhudzana ndi khungu, maso kapena pokoka fumbi lake.

-Valani zida zodzitetezera monga magolovesi oteteza mankhwala, magalasi otetezera ndi masks otetezera pamene mukugwira 2-Mercaptopyrazine.

-Pogwiritsa ntchito mankhwalawa, chonde onetsetsani kuti mukugwirira ntchito pamalo abwino mpweya wabwino kuti musapume fumbi lake.

- Pewani kukhudzana ndi ma oxidants ndi ma acid amphamvu kuti mupewe zoopsa.

-Sungani 2-Mercaptopyrazine mu chidebe chopanda mpweya, kutali ndi kutentha ndi magwero a moto.
