PREPARATION OF OCTAPHOSPHATE BY THE HYDROLYSIS OF CYCLO-OCTAPHOSPHATE

Abstract

The hydrolysis of chain oligophosphates is an acid catalyzed reaction and that of ring oligophosphates is an acid and base catalyzed reaction. According to the hydrolytic property of oligophosphates, the selective ring opening of ring oligophosphate to chain oligophosphate with the same chain length as that of the ring oligophosphate can be expected. The preparation of short-chain condensed phosphate of octaphosphate was achieved by hydrolyzing cyclo-octaphosphate in a strongly basic solution.
