Dihydrogen tetrametaphosphate, its derivatives, and preparation thereof
Dihydrogen metaphosphate can be synthesized via protonation, and can react with a dehydrating agent to afford tetrametaphosphate anhydride. A monohydrogen tetrametaphosphate organic ester can be derived from the anhydride. A metal tetrametaphosphate complex can be prepared using a metal salt and a dihydrogen tetrametaphosphate.
