Multiple experiments of glycerol ketalization/acetalization with aldehydes/ ketones at laboratory scale on discontinuous plants were performed, to convert glycerol into viable biodiesel component. For the ketalization/acetalization of glycerol, 3 aldehydes (acetaldehyde, butyraldehyde and furfuryl aldehyde) and 3 ketones (acetone, methyl-isobutyl ketone and cyclohexanone) were used under acidic heterogeneous catalysis conditions. All ketalization processes have been found to take place with high conversion of glycerol (over 90%). From a technical and economical point of view, the synthesis of the solketal by ketalization of glycerol with acetone appears to be suitable for scale-up to functionalize glycerol as a biodiesel component. © 2019, Politechnica University of Bucharest.
