Carboxymethylcellulose (CMC) and its derivatives are cross-linked by reaction with a carbodiimide. By this reaction, hydrophilic substances are obtained, whose density, in a water solution, is very high and which, under certain conditions, give hydrated gels. These gels are self-destructible and eli ...

Johansson Ake Allan, Roman Alain, Armanet Jean Michel, Sachetto Jean Pierre: Process for the hydrolysis of cellulose into glucose.. Battelle Memorial Institute, November 2, 1983: EP0093088-A2 (1 worldwide citation)

Wet cellulose is treated by gaseous HCl without cooling, which results in a preliminary degradation of the material and deformation of an aqueous acid solution of oligomer sugars. This solution is then supersaturated by HCl in order to complete the hydrolysis, resulting in the formation of reversion ...
