Abstract—In this paper, alkaline hydrothermal experiments of fermentation of starch.[3] However, the fermentation process
glucose, fructose and xylose, the pounds of not only usually takes a long time, but also does not utilize
carbohydrate biomass, were conducted in a batch reactor in the cellulose biomass directly.[4-8] Our research group [9-12] has
temperature range of 250 to 350 oC to examine the production of preliminarily investigated the production of lactic acid from
lactic acid. Result showed that the formation of lactic acid in a glucose by alkaline hydrothermal reaction. The results showed
hydrothermal reaction of glucose, fructose and xylose could be that a fairly high yield of lactic acid from glucose was
o
promoted notably by using NaOH, KOH and Ca(OH)2 as obtained by using sodium hydroxide at temperature of 300 C.
alkaline yield of lactic acid from glucose, fructose
and xylose followed the sequence of fructose > glucose > xylose The purpose of this study was to examine the production of
with NaOH as alkaline catalyst. For fr
