Abstract

In this paper, lactic acid production from C6-polyols is investigated to compare with that from C6-aldoses under hydrothermal conditions. Experiments of C5-polyols and C5-aldoses were also performed. Results showed that the yield of lactic acid from C6-polyols was lower than from both C6-aldoses and glycerine. Reactions of C5-polyols revealed the same results. It is indicated that, being different from both aldoses and glycerine, long chain polyols might follow a different reaction pathway. Further investigation is needed to clarify the reaction mechanism.
