A method of 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 one solvent are used. Specifically, in the presence of [SnCl4-l-ethyl-3-methylimidazolium chloride ([EMIM] CI)], [SnCl4-l, 3-dimethylimidazolium methyl sulfate ([DMIM] CH3SO4)], [SnCl2-l-ethyl-3-methylimidazolium chloride ([EMIM] CI)], or [SnCl2-l, 3-dimethylimidazolium methyl sulfate ([DMIM] CH3S04)] in methanol.
