  • Publication number: 20230097969
    Abstract: A method for producing a phosphate diester or a phosphate triester is provided in which the phosphate diester or the phosphate triester can be produced from phosphoric acid and a hydroxy compound. Phosphoric acid and a phenol, which is used in excess with respect to the phosphoric acid, are subjected to dehydrating condensation with heating and refluxing. Water released during this dehydrating condensation is adsorbed onto a dehydrating material, which is an adsorbent derived from concrete sludge, disposed somewhere in the refluxing channel, thereby producing a phosphate diester or a phosphate triester.
