Taw qhia

2-Methoxy-3-isopropylpyrazine, tseem hu ua MIBP (Methoxyisobutylpyrazine), yog cov organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:

 

Zoo:

- Cov tsos: cov kua tsis muaj xim

- tsw: muaj ntxhiab tsw zoo li ntsuab peppers

 

Siv:

 

Txoj kev:

2-Methoxy-3-isopropylpyrazine tuaj yeem ua ke los ntawm cov kauj ruam hauv qab no:

Sodium sulfate thiab sodium bicarbonate yog siv los kho tus nqi pH.

Pyrazine, isopropyl magnesium bromide, thiab methanol hnov ​​​​mob ntawm qhov tsim nyog.

Tom qab cov tshuaj tiv thaiv tiav, cov ntshiab compound yog distilled thiab crystallized.

 

Cov ntaub ntawv kev nyab xeeb:

- 2-Methoxy-3-isopropylpyrazine muaj toxicity tsawg tab sis tseem yuav tsum muaj kev nyab xeeb ntawm cov tshuaj yuav tsum tau ua raws.

- Tsis txhob sib cuag nrog daim tawv nqaij, qhov muag, thiab cov mucous daim nyias nyias. Thaum muaj kev sib cuag, yaug tam sim nrog dej ntau.

- Tsis txhob nqus cov vapors lossis hmoov av los ntawm qhov sib xyaw.

- Thaum siv los yog khaws cia, khaws cia kom deb ntawm qhov hluav taws kub thiab cov khoom siv hluav taws xob.

- Yuav tsum khaws cia rau hauv qhov chaw txias, qhuav thiab qhov cua zoo, kom deb ntawm cov kua qaub thiab oxidants.
