Taw qhia thiab daim ntawv thovntawm CAS 109-08-0|2-Methylpyrazine
2-Methylpyrazine yog cov kua tsis muaj xim, tsis muaj kuab lom uas muaj ntxhiab tsw. Nws yog siv raws li ib tug additive nyob rau hauv cov zaub mov thiab dej haus rau impart ib roasted tsw.
Methylpyrazine yog tsim los ntawm lub voj voog redox nyob rau hauv uas nws yog oxidized rau pyrazinoic acid thiab tom qab ntawd txo rov qab mus rau qhov qub compound. Cov txheej txheem no tuaj yeem ua rau cov khoom siv tooj liab lossis lwm yam hlau ions, xws li npib tsib xee lossis hlau. Cov nitrogen atom hauv pawg methyl ntawm lub nplhaib pyrazine ua haujlwm nrog cov hlau ion, thaum cov ethylene diamine ligand ua haujlwm nrog cov pa atom ntawm cov hlau ion.
Cov txheej txheem tshuaj tiv thaiv ntawm hom kev sib koom ua ke geometry no suav nrog cov pab pawg carbonyl thiab hydrogen atoms, uas tau pauv los ntawm 2-methylpyrazine rau ethylene diamine. Cov tshuaj tiv thaiv no tshwm sim los ntawm ntau cov tshuaj tiv thaiv uas suav nrog cov kauj ruam oxidation, ua raws li ob theem txo qis uas thaum kawg ua rau kev tsim dej thiab 2-methylpyrazine.
Daim ntawv thov:
2-Methylpyrazine yog siv nyob rau hauv dyeing thiab tshuaj industries, thiab kuj siv los ua zaub mov tsw additives.
