Summary

Hydrolytic degradation of lithium polyphosphate catalyzed by ethanol was studied. Two samples with endgroup molecular weights of 4300 and 5500 were used. They were dissolved in 0.1 M NaBf and 30% (v/v) ethanol was used as the catalyst. The hydrolytic degradation of the samples catalyzed by 0.1 M hydrochloric acid was also studied. Kinetic results show that the energies of activation obtained for ethanol-catalyzed reactions were comparable to those obtained for acid-catalyzed reactions. The results are similar to those obtained earlier for water-soluble long-chain sodium polyphosphates and the mechanism of nucleophilic attack is also expected to be the same.
