Efficient electrophilic catalysis of 1,5-anhydrocellobiitol hydrolysis by Al(III); implications for the conservation of "rosin-alum" sized paper

Chem Commun (Camb). 2004 Apr 7:(7):866-7. doi: 10.1039/b316417a. Epub 2004 Feb 27.

Abstract

Added Al2SO4 greatly accelerates the hydrolysis at 150.0 degrees C of 1,5-anhydrocellobiitol, a model for the beta(1 --> 4) linkages in cellulose, in succinate buffers of room temperature pH 3.05 and 3.35; E(a) values for 20 mM Al(III)- and H+-catalysed hydrolyses are 109 +/- 3 and 140 +/- 1 kJ mol(-1), respectively.
