Hydrothermal Dehydration of Aqueous Fructose Solutions in a Closed System

Abstract

Aqueous monosaccharide solutions including glucose or fructose have been hydrothermally treated in a closed system to form colloidal carbon spheres. In-situ Raman and 13 C NMR have been used to quantify the intramolecular dehydration moiety, HMF, as an intermediate. An aqueous glucose solution forms a carbon sphere via an intermolecular dehydration route without forming HMF during initial hydrothermal treatment and followed by carbonization at 170−180 °C. However, an aqueous fructose solution initially forms HMF by intramolecular dehydration at 120−140 °C. Upon subsequent polymerization, microscopic carbon-containing spheres assemble to larger spheres, thereby generating a grain-like surface morphology. The carbon sphere contains a dense hydrophobic carbon core and a hydrophilic shell.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
