Saponification

Saponification es le reaction chimic hydrolyse inter acidos grasse e un hydroxydo, per exemplo hydroxydo de sodium (${\mathsf {NaOH}}$) o hydroxydo de potassium (${\mathsf {KOH}}$). Le resultato es sales del acido e alcohol. Le sales del acidos grasse es nominate sapones.

Le reaction con NaOH

acido grasse $+$ 3 vices hydroxydo de sodium $\longrightarrow$ alcoholo $+$ 3 vices sapon
