Abstract

The invention relates to a method for obtaining glycidol in a semi-continuous or continuous manner by decarboxylating glycerol carbonate at reduced pressure, at a temperature less than or equal to 130° C. and in the presence of alkoxide catalysts of alkaline metals and alkaline earth metals, metal oxides, mixed metal oxides, metal stannates and mixed metal stannates, all of which optionally supported via SiO, γ-AlO, MgO and ZrO.
