  • Process for preparing phosphoric ester
    Patent number: 6710199
    Abstract: A process for preparing a phosphoric ester having reduced odor, comprising contacting a phosphoric ester with at least one of an inert gas and steam at 100° to 160° C. in a packed tower; a process for preparing a phosphoric ester having reduced odor, comprising repeating a set of processes comprising (A) heating a phosphoric ester, and contacting the heated phosphoric ester with at least one of an inert gas and steam; and (B) cooling the phosphoric ester obtained in the step (A); a process for preparing a phosphoric ester having reduced odor, comprising adding water to a phosphoric ester, and distilling water from the phosphoric ester under reduced pressure; and a process for preparing a phosphoric ester having reduced odor, comprising reacting an organic hydroxy compound with a phosphorylation agent, while introducing an inert gas into the mixture of the organic hydroxy compound and the phosphorylation agent.

  • Method for purifying sugar phosphates or their salts
    Patent number: 4787940
    Abstract: A novel method for purifying a sugar phosphate or its salt, in which a sugar-containing mixture of a sugar phosphate or its salt and phosphoric acid or its salt is subjected to electrodialysis to remove the phosphoric acid or its salt from the mixture.According to this method, the phosphoric acid or its salt can be readily obtained in a reusable form. The method is thus quite advantageous in view of the economy.
