SEPARATING TOLUENE DIISOCYANATE AND/OR HIGHER BOILING SOLVENTS FROM DISTILLATION RESIDUES OF THE TOLUENE DIISOCYANATE MANUFACTURE USING A FLUIDIZED BED A process for separating toluene diisocyanate and/or higher boiling solvents from distillation residues obtained from the phosgenation of toluene diamine in the presence of solvents wherein the separation takes place in a fluidized bed at temperatures of 140.degree.C to 280.degree.C.
