Abstract

Model compounds of oxidized anhydroglucose units in cellulosic materials, carrying 13C isotopic labels at specific positions, have been synthesized starting from commercially available 1-13C-D-glucose (14.7%) and 3-13C-Dglucose (6.3%), respectively, over 10 linear steps. To ensure high yields, the synthetic route was optimized with non-labeled material beforehand. The labeled compounds are used in studies of chromophore formation, yellowing, brightness reversion and aging of cellulosics.

Keywords: Cellulose, aging, yellowing, brightness reversion, isotopic labeling, 3-keto-glucose
