Abstract: The invention relates to a method for the production of diaminodiarylmethanes, comprising the steps: a) reaction of an aromatic amine with an agent liberating methylene groups in the presence of homogenous acid catalysts, b) removal of the homogenous acid catalyst from the reaction product, c) work-up and purification of the reaction product, whereby the homogenous acid catalyst is removed from the reaction mixture by adsorption on a solid adsorption agent.

Abstract: The invention relates to a method for producing isocyanates by reacting amines with phosgene in the presence of inert organic solvents inside a reactor and by subsequently processing the reaction mixture exiting the reactor. The invention is characterized in that the separating out of the solvent ensues in a two-step or multi-step, preferably two-step distillation process, and the solvent is separated out in a first apparatus under a pressure of 0.1 to 15 bar and in a second or other apparatuses under a pressure of 1 to 900 mbar. The condensation heat of the solvent vapor from the first apparatus is used for partially or completely vaporizing solvent in the second apparatus.

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.
