    摘要： The present invention relates to a method for decomposing and recovering an isocyanate compound, which comprises; continuously mixing and dispersing into water at high pressure and high temperature an isocyanate compound having at least one isocyanate group or group derived from an isocyanate group in a molten state or solution state, supplying a liquid mixture containing the isocyanate compound and the water at high pressure and high temperature continuously to a reactor, followed by subjecting the isocyanate compound to a decomposition reaction in the reactor, and recovering a raw material for the isocyanate compound or a derivative thereof, and an apparatus for decomposing and recovering an isocyanate compound, which comprises: a reactor which brings water at high pressure and high temperature into contact with an isocyanate compound having at least one isocyanate group or group derived from an isocyanate group to cause a decomposition reaction, a water supply line which continuously supplies the water at high pressure and high temperature to a reactor, a compound supply line which continuously supplies the isocyanate compound in a molten state or solution state to the water supply line, an on-off valve which communicates the compound supply line with a vicinity of a communication portion of the water supply line to the reactor, a dehydrating device which conducts a dehydration of a decomposition reaction product discharged from the reactor, and a purification device which purifies the decomposition reaction product after the dehydration.
