摘要：
The invention relates to a process for the work-up of residues from the production of isocyanates, which comprises the steps: a) hydrolysis of the residues by means of water, b) introduction of the reaction product from step a) into a mixer having a heat transfer surface, c) separation of amine and water from the output from step b), d) separation of water and amine.
