摘要： Processes for preparing tri- and tetraoxymethylene glycol dimethyl ether (POMDMEn=3,4) include feeding a reaction mixture of an aqueous formaldehyde solution and methanol into a reactive evaporator and separating into a first low boiler fraction and a first high boiler fraction, recycling the first high boiler fraction into the reactor, feeding the first low boiler fraction into a first distillation column and separating into a second low boiler fraction and a second high boiler fraction, recycling the second high boiler fraction into the reactive evaporator, feeding the second low boiler fraction into a second distillation column and separating into a third low boiler fraction and a third high boiler fraction, feeding the third high boiler fraction into a phase separation apparatus and separating into an aqueous phase and an organic phase, and feeding the organic phase into a third distillation column and separating into a low and high boiler fractions.

摘要： The present invention relates to a process for preparing isocyanates by reaction of amines with phosgene in a reactor and subsequent separation of the isocyanate from the reaction mixture leaving the reactor and purification of the isocyanate, wherein the separation and purification of the isocyanate is carried out in a column having a pressure at the top of 1-950 mbar, preferably 5-50 mbar, particularly preferably 10-20 mbar, and a temperature at the bottom of 90-250° C., preferably 120-170° C., particularly preferably 130-150° C., and the pure isocyanate stream is preferably taken off in liquid or gaseous form at a side offtake of the column.

摘要： Production of polyisocyanates comprises mixing an amine with phosgene, reacting the amine with the phosgene in a tubular reactor, and passing the reactor effluent to a distillation column. Independent claims are also included for: (1) tubular reactor consisting of one or more horizontal and/or vertical segments connected together by sections whose diameter is smaller than that of the narrowest horizontal or vertical segment; (2) use of the above reactor for carrying out gas-liquid reactions; and (3) use of the above reactor for producing isocyanates by reacting primary amines with phosgene.
