Abstract

Procedure for the preparation of glycerin, characterized in that glycerin acetates are hydrolyzed in countercurrent with water at temperatures of 150 to 300ºC and pressures of 1 to 40 absolute atmospheres in the absence of catalysts and acid is removed from the upper part of the reaction zone aqueous acetic and glycerin is removed at the bottom of the reaction zone.
