  • Dihydrogen tetrametaphosphate, its derivatives, and preparation thereof
    Patent number: 10941039
    Abstract: 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.
    Type: Grant
    Filed: July 1, 2018
    Date of Patent: March 9, 2021
    Assignee: MASSACHUSETTS INSTITUTE OF TECHNOLOGY
    Inventors: Yanfeng Jiang, Khetpakorn Chakarawet, Julia Stauber, Christopher Colin Cummins
