Abstract

See full text

Crude glycerol obtained from raw materials, such as the glycerol obtained during the production of biodiesel or glycerol obtained during the conversion of fats or oils, is purified by forming a dioxolane therefrom by reacting the crude glycerol with a ketone or aldehyde, separating the dioxolane thus formed, converting the dioxolane into purified glycerol and ketone/aldehyde, and recovering the glycerol thus purified.
