Abstract:  Thermolytic reactions of cellulose have been studied by methods of thermal analysis and by the GC—MS analysis of products obtained from these reactions. It has been found that both 3,6-anhydride of D-glucose and l,4:3,6-dianhydro-α-D-glucopyranose are formed during heating of cellulose in the temperature range 200—300 °C. It has been concluded that the dehydration reactions proceeding at that range of temperature lead to the dehydropolysaccharides formation. 3,6-Dehydration is supposed to be one of the possible dehydration reactions, which take place during heating of cellulose polymers.
