Cannizzaro Reaction of Formaldehyde

2HCHO + NaOH → HCOONa + CH3OH

개요

In the Cannizzaro reaction, two molecules of a non-enolizable aldehyde undergo disproportionation in the presence of strong base. One molecule is oxidized to a carboxylate salt while the other is reduced to an alcohol. Formaldehyde disproportionates to sodium formate and methanol.
