ABSTRACT:
Processes for the conversion of glycerol to a product mixture of an amino alcohol product and propylene glycol are disclosed. Glycerol is converted to hydroxyacetone and the hydroxyacetone is reduced with a reducing agent or reacted with an amine compound to give an adduct which is reduced using the reducing agent to obtain a product mixture of propylene glycol and an amino alcohol product.
