METHOD FOR WORKING UP DISTILLATION RESIDUES FROM ISOCYANATE PRODUCTION

The present invention relates to a method for working up distillation, residues from isocyanate production in which monomeric isocyanate present in distillation residues is recovered by means of a spray-dry method and the overall yield of monomeric isocyanate is thus significantly increased.
