摘要：
A study of the liquid-phase conversion of biomass-derived sugars directly to methyl lactate catalyzed over solid base catalysts is presented. The yield of methyl lactate reached 29.45% under optimal reaction conditions. The effects of reaction time, reaction temperature, and catalysts calcination temperature were investigated. Fresh and used catalysts were characterized by XRD, CO2-TPD, and N-2-adsorption techniques. MgO with the highest concentration of weakly basic sites was found to show the highest catalytic activity for the conversion of sugars to methyl lactate. (C) 2011 Elsevier B.V. All rights reserved.
