Abstract: The invention relates to a method for producing a heat exchanger. Said method is characterised in that a metal polymer dispersion layer having a halogenated polymer is chemically deposited on a heat exchange surface in a currentless manner. The invention also relates to a method for producing a heat exchanger. Said method is characterised in that a metal phosphor layer having a thickness of 1 to 15 mu m is applied by currentless chemical deposition before the metal polymer dispersion layer is applied. The invention also relates to a heat exchanger which can be produced by an inventive method and to the utilisation of a coating which is produced by currentlessly, chemically depositing a metal polymer dispersion layer having a halogenated polymer in order to make the coated surfaces less likely to accumulate solid materials from fluids whereby deposits are formed.

Abstract: The invention relates to a method for coating a reactor. Said method is characterised in that a metal layer or a metal polymer dispersion layer is deposited on the inner surface of the reactor in a currentless manner by contacting the surfaces to a metal electrolytic solution which contains a reduction means and a halogenated polymer in dispersed form in addition to the metal electrolyte. Said halogenated polymer can optionally be deposited.

Abstract: A process is proposed for distilling ethylene oxide from a mixture containing ethylene oxide in a column at an absolute pressure of 2-10 bar and a temperature of 20-180 ~C; pure ethylene oxide is removed at the top or through a side discharge in the column and distillation takes place in a column divided up internally into a number of successive zones with structured sheet metal packs or piles of fillers, one or more quenching systems located outside the column being allocated to said zones.

Abstract: A method for reacting a solution containing a mixture of at least two chemicals in chemical equilibrium with other chemical(s) involves: (a) separating the solution into at least two fractions, enriched in the various compounds relative to the equilibrium concentrations; and (b) reacting one fraction with the other reactant(s) before equilibrium is completely restored. A method for reacting a solution containing a mixture of at least two chemicals in chemical equilibrium with other chemical(s) involves: (1) separating the solution into at least two fractions, enriched in the various compounds relative to the equilibrium concentrations; and (2) reacting one fraction with the other reactant(s) before equilibrium is completely restored.
