Summary:The invention relates to a process for distillative removal of a unsaturated carboxylic anhydride of the general formula (I) R-C(O)-O-C-(O)-R in which R is an unsaturated organic radical having 2 to 12 carbon atoms, wherein said unsaturated carboxylic anhydride is discharged in gaseous form from a sidestream take-off and is condensed in an atomized liquid circulating stream of said unsaturated carboxylic anhydride.
