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 producing polyisocyanates by reacting primary amines with phosgene, comprising the following steps: a) mixing the amine with the phosgene; b) reacting the amine with the phosgene in a reactor, inside of which the mixture stays for a period of time and, optionally; c) transferring the discharge from the reactor from step b) into a distillation column. The invention is characterized in that the reactor cited in step b) is provided in the form of a tubular reactor.

Abstract: The invention relates to an integrated method for producing trioxane from formaldehyde. According to said method, a flow A1 containing water and formaldehyde and a return flow B2 consisting essentially of water and formaldehyde are introduced into a trioxane synthesis reactor in which the formaldehyde is converted into trioxane, forming a product flow A2 containing trioxane, water and formaldehyde; the flow A2 is introduced into a first distillation column and distilled at a pressure of between 0.1 and 2.5 bar, forming a trioxane-enriched flow B1 and the flow B2 consisting essentially of water and formaldehyde; the flow B1 and a return flow D1 containing trioxane, water and formaldehyde are introduced into a second distillation column and distilled at a pressure of between 0.2 and 17.5 bar, forming a product flow C2 consisting essentially of trioxane and a flow C1 containing trioxane, water and formaldehyde; and the flow C1 is introduced into a third distillation column and distilled at a pressure of between 0.1 and 2.5 bar, forming the return flow D1 containing trioxane, water and formaldehyde and a flow D2 consisting essentially of water and formaldehyde.
