Abstract

Cellulose, a commonly found carbohydrate, exhibits exothermic decomposition, when heated above 180‡C. These reactions have been detected and quantified by a range of thermal analysis and calorimetric techniques giving complementary information. The presented results are of interest for process safety.

Zusammenfassung

Cellulose, ein weit verbreitetes Kohlenhydrat, zeigt beim ErwÄrmen auf Temperaturen oberhalb 180‡C exotherme Zersetzung. Die damit verbundenen Reaktionen wurden mittels einer Reihe komplementÄrer thermoanalytischer und kalorimertrischer Methoden erfasst und quantifiziert. Die vorgestellten Resultate sind für die AbschÄtzung von Prozessrisiken bedeutungsvoll.
