Abstract

In this paper, the hydrothermal conversion of glucose to lactic acid (LA) using sodium silicate (Na₂SiO₃) as a mild base catalyst was investigated. The results showed that Na₂SiO₃ was effective catalyst for the conversion of glucose. The highest LA yield of about 30% was obtained from glucose with a lower concentration of Na₂SiO₃ at 300 °C for 60 s. It was also found that the use of Na₂SiO₃ led to a much less corrosion and a higher LA yield than that with NaOH at the same pH value. This process provides an environmentally friendly and highly effective method toward the synthesis of useful LA from glucose.
