1. A method for producing glycidol by decarboxylating glycerol carbonate, which comprises the steps:

  • a) Placing into contact glycerol carbonate with a catalyst selected from the group consisting of (C1-C2) alkoxides metal oxides, mixed metal oxides, metal stannates, mixed metal stannates and mixtures thereof; and

    b) Carrying out the reaction at a temperature less than or equal to 130°

    C. at reduced pressure to continuously separate the glycidol formed by evaporation, wherein the (C1-C2) alkoxides, metal oxides, mixed metal oxides, metal stannates, and mixed metal stannates are of alkaline metals or alkaline earth metals.
