  • Synthesis of Lactic Acid and Alkyl Lactate from Carbohydrate-Containing Materials
    Publication number: 20130231497
    Abstract: A method for synthesizing lactic acid and lactate is invented from carbohydrates, such as monosaccharides and/or polysaccharides in the presence of the catalyst that is the combinations of nitrogen-heterocycle aromatic ring cation salts and metal compounds. In the reaction, at least one alcohol and at least one solvent are used. Specifically, in the presence of [SnCl4-1-ethyl-3-methylimidazolium chloride ([EMIM]Cl)], SnCl4-1, 3-dimethylimidazolium methyl sulfate ([DMIM] CH3SO4)], [SnCl2-1-ethyl-3-methylimidazolium chloride ([EMIM]Cl)], or SnCl2-1, 3-dimethylimidazolium methyl sulfate ([DMIM] CH3SO4)] in methanol.
