Fat + methanol $\to$ glycerol
Meant to be more sustainable?!??!?
Enviromental conditions
heating
$OH^{-}$
Note Biodiesel synthesis + sapponification have same catalyst/environmental requirements!
We can use either:
As catalysts for biodiesel
sapponification, biodiesel synthesis, quite similar
$$\text{Tryglyceride(fat)} + \frac{NaOH}{CH_{3}OH}\to + \text{Glycerol} + \frac{\text{Soap}}{Biodiesel} + H_{2}O $$(no ratios included)
ESTER FORMATION $\implies$ $H_{2}SO_{4}$ ESTER BREAKING (sapponification, biodiesel) $\implies$ $OH^{-}$
