1. A process for removing phosphatides from triglyceride oils which are substantially liquid at 40°

  • C. comprising the steps of dispersing an acid or acid anhydride in the oil, said acid or acid anhydride having a pH of from 0.5 to 7 as measured at 20°

    C. in a one molar aqueous solution and said oil at a temperature of from 20°

    to 100°

    C., adjusting the temperature of the mixture to the range of from the lowest temperature at which the oil remains a liquid to 40°

    C., dispersing from 0.2 to 5 percent by weight of water in the mixture;

    maintaining the temperature of the mixture of oil, acid and water from 5 minutes to several days; and
