    摘要： This invention relates to a process for working up residues from production of isocyanates. This process involves hydrolyzing residues from production of at least one isocyanate with water to form a hydrolysis product, and processing the hydrolysis product within an extruder or a kneader having a heat transfer surface, to form a mixed product containing at least one amine and water. The amine and the water are separated from the mixed product to form an amine/water mixture, which is then separated to obtain the water and the amine. The process may also involve separating all or part of the water from the hydrolysis, or separating part of the amine from the hydrolysis, prior to the processing of the hydrolysis product.
