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 2 , γ-Al 2 O 3 , MgO and ZrO 2 .

Claim (Index 1):
A method for producing glycidol by decarboxylating glycerol carbonate, which comprises the steps:\n a) Placing into contact, optionally in the presence of an organic solvent, glycerol carbonate with a catalyst selected from the group consisting of (C 1 -C n ) alkoxides of alkaline metals and alkaline earth metals, metal oxides, mixed metal oxides, metal stannates, mixed metal stannates and mixtures thereof, wherein the catalyst is optionally supported via a support selected from the group consisting of SiO 2 , \u03b3-Al 2 O 3 , MgO and ZrO 2 ; and b) Carrying out the reaction at a temperature less than or equal to 130\u00b0 C. at reduced pressure to continuously separate the glycidol formed by evaporation.
