| dc.description.abstract | We herein present a study on the application of homogeneous
catalysts in the form of metal salts on the conversion of trioses,
such as dihydroxyacetone (DHA), and glyceraldehyde (GLY) to
lactic acid (LA) in water. A wide range of metal salts (26 in
total) were examined. Al salts were identified as the most
promising and essentially quantitative LA yields (>90 mol%)
were obtained at 1408C and a reaction time of 90 min. A reaction
pathway is proposed and a kinetic model using the power law approach was developed for the conversion of DHA to LA
with pyruvaldehyde (PRV) as the intermediate. Good agreement
between experimental data and the model was obtained.
Model predictions, supported by experiments, indicate that a
high yield of LA is favoured in dilute solutions of DHA (0.1 m)
at elevated temperatures (180 8C) and reaction times less than
10 min. | en_US |
