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

Intangiriro

2-Mercaptopyrazine ni ifumbire mvaruganda hamwe na formula ya chimique C4H4N2S. Nibintu byera bya kristalline ikomeye kandi ifite impumuro nziza. Ibikurikira nubusobanuro bwa kamere, imikoreshereze, imyiteguro namakuru yumutekano ya 2-Mercaptopyrazine:

Kamere:

-Ibigaragara: Crystalline yera ikomeye

-Uburemere bwa molekulari: 112.16g / mol

ingingo yo gushonga: 80-82 ℃

-Ibintu bitetse: hafi 260 ℃ (kubora)

-Gukemuka: Gushonga muri aside, alkali, Ethanol na ether, gushonga gake mumazi.

Koresha:

- 2-Mercaptopyrazine irashobora gukoreshwa nkigihe cyingenzi muguhuza ibinyabuzima kandi irashobora kugira uruhare runini muguhuza imiti nudukoko twangiza.

-Bishobora gukoreshwa mugutegura amarangi ya pyrazine, abahuza imiti hamwe nibikoresho byo guhuza.

Uburyo bwo Gutegura:

2-Mercaptopyrazine irashobora guhuzwa:

1. Igisubizo cya 2-bromopyrazine hamwe na sodium hydrogen sulfate mumazi / Ethanol kugirango itange 2-Mercaptopyrazine. Imiterere yimyitwarire isanzwe nkiyo reaction ikangurwa nubushyuhe bwicyumba.

2. 2-Mercaptopyrazine irashobora kandi kuboneka mugukora 2-chloropyrazine hamwe na thiol mugihe cya alkaline.

Amakuru yumutekano:

- 2-Mercaptopyrazine nuruvange rushobora gutera uburakari uhuye nuruhu, amaso cyangwa guhumeka umukungugu.

-Kwambara ibikoresho birinda umuntu nka gants zo kurinda imiti, ibirahure byumutekano hamwe na masike yo gukingira mugihe ukoresha 2-Mercaptopyrazine.

-Iyo ukoresheje iyi compound, nyamuneka urebe neza ko ukorera ahantu hafite umwuka uhagije kugirango wirinde guhumeka umukungugu wacyo.

-Irinde guhura na okiside na acide zikomeye kugirango wirinde ingaruka mbi.

-Bika 2-Mercaptopyrazine mubikoresho byumuyaga, kure yubushyuhe ninkomoko yumuriro.
