Abstract
A process for the production of dioxolane compounds of formula (I), wherein R1 and R2 independently represent hydrogen or an alkyl chain from 1 to 10 carbon atoms; R3 and R4 independently represent hydrogen, an alkyl chain from 1 to 5 carbon atoms or an alkyl chain from 1 to 5 carbon atoms endowed with one or more hydroxyl groups. Such process comprises successively a reaction step between crude glycerol and aldehyde or ketone and a liquid-liquid extraction step with an extracting ketonic solvent corresponding to formula (II) with A and B independently being an alkyl chain with 2 to 10 carbon atoms, or phenyl, A and B not comprising hydroxyl functions.
