Abstract: The present invention relates to a process for the production of isocyanates, preferably diisocyanates and polyisocyanates of the diphenylmethane series (MDI), by reacting an amine with phosgene in the liquid phase or in the gas phase to form the corresponding isocyanates, subsequent removal of the solvent in at least two steps to obtain at least two solvent streams, individual treatment of the at least two solvent streams, and recirculation of at least a portion of the solvent streams.

Abstract: The invention relates to a method for partially or completely separating a substance mixture consisting of hydrogen chloride and phosgene, optionally of solvents and optionally of low-boiling fractions and inert substances such as those that normally arise during the production of isocyanates by reacting amines with phosgene. The inventive method is characterized in that a partial or complete condensation of phosgene is firstly carried out followed by a distillation or stripping inside a column for removing the hydrogen chloride from the bottom product phosgene and lastly, a washing of the top product hydrogen chloride with the process solvent for absorbing the phosgene in the process solvent is carried out. A subsequent purification by means of adsorption on activated carbon or other appropriate methods can be used for removing solvent remnants.

Abstract: The invention relates to a method for producing isocyanates by reacting amines with phosgene inside a reactor followed by separating the isocyanate out from the reaction mixture exiting the reactor and purifying this isocyanate. The invention is characterized in that the isocyanate is separated out and purified in a column with a top pressure of 1 to 950 mbar, preferably 5 to 50 mbar, particularly preferred 10 to 20 mbar, with a bottom temperature of 90 to 250 °C, preferably 120 to 170 °C, particularly preferred 130 to 150 °C, and that the pure isocyanate flow is withdrawn in liquid or gaseous form, preferably in a side-stream of the column.
