2-Kev siv Methylbutyraldehyde thiab Synthesis

Kev piav qhia	2-Methylbutyraldehyde muaj lub zog, choking tsw nrog ib tug peculiar cocoa thiab kas fes zoo li tsw thaum diluted. Nws muaj qab zib, me ntsis fruity, zoo li chocolate saj. Tej zaum yuav tau npaj los ntawm oxidation ntawm sec-butylcarbinol cais los ntawm fermented fusel roj; dl-daim ntawv los ntawm sec-butyl magnesium bromide thiab formaldehyde; los ntawm kev txo qis methylethylacetic acid.
Chemical Properties	2-Methylbutyraldehyde muaj lub zog, choking tsw nrog ib tug peculiar cocoa thiab kas fes zoo li tsw thaum diluted. Qhov sib xyaw no kuj tau tshaj tawm tias muaj qab zib, me ntsis fruity, chocolate zoo li saj.
