N2 - In this paper, alkaline hydrothermal experiments of glucose, fructose and xylose, the model compounds of carbohydrate biomass, were conducted in a batch reactor in the temperature range of 250 to 350°C to examine the production of lactic acid. Result showed that the formation of lactic acid in a hydrothermal reaction of glucose, fructose and xylose could be promoted notably by using NaOH, KOH and Ca(OH)2 as alkaline catalysts.The yield of lactic acid from glucose, fructose and xylose followed the sequence of fructose > glucose > xylose with NaOH as alkaline catalyst. For fructose, high lactic acid yields of 43.5% with NaOH and 46% with KOH on the carbon base were obtained at the temperature of 300°C.
