Cov khoom lag luam
Ethyl Vanillin yog cov organic sib xyaw nrog cov mis (c2h5o) (ho) c6h3cho. Cov khoom tsis muaj xim no muaj lub nplhaib benzene nrog hydroxyl, kev ua siab, thiab cov pab pawg tsim ua rau 4, 3, thiab 1 txoj haujlwm, feem.
Ethyl Vanillin yog cov hluavtaws molecule, tsis pom muaj nyob hauv qhov xwm. Nws tau npaj los ntawm ntau kauj ruam los ntawm catechol, pib nrog kev ua kom zoo rau muab "TheTethol". Qhov no ithers tov nrog glyoxylic acid los muab cov qauv ua kom zoo nkauj rau cov neeg mandelic acid derivative, uas ntawm oxidation thiab decarboxylation muab vanillin.
Raws li ib qho flasant, Ethyl Vanillin yog hais txog peb zaug raws li muaj zog li vanillin thiab yog siv nyob rau hauv kev tsim cov chocolate.
