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.
摘要:
A process for removing residues from the microstructure of an object is provided, which comprises steps of preparing a remover including CO2 and additive for removing the residues and a co-solvent dissolving the additive in said CO2 at a pressurized fluid condition; and bringing the object into contact with the remover so as to remove the residues from the object. An apparatus for implementing the process is also provided.
