摘要： An apparatus for decomposing an isocyanate compound having at least one isocyanate group and/or group derived from the isocyanate group in order to recover the compound in the form of the starting material or derivatives thereof, which apparatus comprises hydrolysis means by which the compound to be decomposed is contacted in a reactor under a high pressure substantially only with liquid water heated to 190 to 370 °C to hydrolyze the compound, and post-treatment means by which the decomposition products discharged from the reactor are subjected to post-treatments, e.g., dehydration, addition, distillation, separation, and liquid separation.
