N2 - An improved, environmentally sound three-component system, MTO/H2O2/LiBr, used to prepare biodegradable oxidized starch super absorbers is reported. In contrast to previous systems (ref. 1: W. A. Herrmann, J. P. Zoller and R. W. Fischer, J. Organomet. Chem., 1999, 579, 404), a highly acidic reaction media is avoided, thus limiting product depolymerisation to a low level. This paper presents an optimized catalytic approach to make carboxy starch, which reduces overall reaction cost, and produces less harmful waste.
