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.

18. A process for converting glycerol to a product mixture comprising propylene glycol and a 2-amino-1-propanol comprising:
-
reacting glycerol with a metal catalyst in a first reactor to obtain hydroxyacetone; and
reacting the hydroxyacetone with a reducing agent or an amine compound and the reducing agent to obtain a product mixture comprising propylene glycol and a 2-amino-1-propanol, wherein reacting the hydroxyacetone comprises;
reducing a first portion of the hydroxyacetone in a reactor with the reducing agent to produce the propylene glycol in the product mixture; and
reacting a second portion of the hydroxyacetone with the amine compound to produce an adduct and reducing the adduct with the reducing agent in the reactor to produce the 2-amino-1-propanol in the product mixture. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)
