Decomposition Kinetics of Maltose in Subcritical Water
Bioscience, Biotechnology, and Biochemistry, 2004 The decomposition process of maltose in subcritical water was studied using a tubular reactor in the temperature range of 180 to 260 degrees C and at 10 MPa. The formation of glucose and 5-hydroxymethyl-2-furaldehyde during the maltose decomposition was also observed. The decomposition rate of maltose was faster at higher temperatures.

Degradation Kinetics of Glucuronic Acid in Subcritical Water [PDF]
Bioscience, Biotechnology, and Biochemistry, 2010 The degradation kinetics of glucuronic acid (GlcA) under subcritical conditions from 160 to 200 degrees C was studied in a continuous tubular reactor. The formation of glucuronolactone (GlcL) during the treatment of GlcA in subcritical water was substantiated by ESI-TOF-MS and (1)H NMR.
