Abstract: Production of amine-formaldehyde condensate involves fractionating a mixture of polyoxymethylene glycols, formaldehyde, methylene glycol and water in a reaction column and reacting the reactive fraction with a countercurrent of amine in the same column. Production of amine-formaldehyde condensates (I) by reacting: (a) amine(s); with (b) a mixture containing: (i) poly-oxymethylene glycols; (ii) monomeric formaldehyde; (iii) methylene glycol; and (iv) water. The method involves fractionation of mixture the, followed by reaction with the amine in a reaction column. The amine and that part of the fractionated mixture (b) which reacts with (a) move in countercurrent to one another.

Abstract: Crude ammonia is separated into a low boiler fraction, a high boiler fraction and an intermediate-boiling pure fraction by continuous fractional distillation in a distillation apparatus configured either as a dividing wall column or as a system of thermally coupled distillation columns. In the process of the present invention, the low boiler fraction is taken off at the top of the distillation apparatus. The intermediate-boiling pure fraction is obtained at a side offtake which is preferably provided with droplet precipitators. In addition, the gas loading of the distillation column is restricted so that the operating pressure is in the range from 2 to 30 bar and the F factor does not exceed 2.0 Pa 0.5 .

Abstract: A catalyst packing which can be produced by vapor deposition and/or sputtering of at least one substance active as catalyst and/or promotor onto woven or knitted fabrics or sheets as support material is used in a process for catalytic distillation in which a heterogeneously catalyzed reaction is combined with a simultaneous distillation or rectification over the catalyst packing.

Abstract: The invention relates to a method for producing alkali methylates from an aqueous alkaline lye that is optionally mixed with methanol and methanol in a reaction column, said column comprising at least 5, preferably 15 to 30 theoretical trays between the inlet of the alkaline lye and the site of addition of the methanol. According to the inventive method, the vapor methanol-water mixture formed during the reaction is separated in a reaction column. According to an embodiment of the invention, the reaction column that is configured as a bubble-tray, valve-tray or sieve-plate column is provided with trays, each letting through maximally 5 %, preferably

Abstract: A distillation process and assembly separate a mixture consisting of a substance with a high melting point (m.p.) and a seco substance or mixture of substances with a lower m.p. A distillation process and assembly separate a mixture consisting of a substance (2) with a high melting point (m.p.) and a second substance or mixture of substances with a lower m.p. The starting mixture incorporating the substance (1) of low boiling point (b.p.) is released into the distillation apparatus, which consists of a partitioned column or of a thermally-coupled distillation column. The head of the distillation apparatus is positioned above the tapping outlet for the higher m.p. substance (2). Part of the condenser surface is of lower temperature than that of the higher m.p. substance. The light substance (1) in th head is strongly enriched, preventing separation of the higher m.p. substance (2) on the condenser.
