Abstract: A process for recovering caprolactam and its oligomers by removing inorganic impurities from aqueous polycaprolactam extracts, in which the aqueous extract is continuously passed through an evaporator in such a way that the impurities are deposited on the heat exchange surfaces of the evaporator.

Abstract: Column plates for a material exchange column, esp. with a peripheral supporting ring and supporting elements holding plates with through-holes, esp. perforations, valves or bubble caps comprise: (1) a liquid-tight join, pref. weld, esp. in discrete areas, between (a) the plates and the supporting elements and/or ring, (b) the supporting elements and (c) the supporting elements and the wall of the column or supporting ring; and (2) adjacent plates and supporting elements are sepd. from one another and from the column wall or supporting ring by gaps with a width of 1-15, pref. 1-7 mm. Also claimed are material exchange columns with plates of this type and a method of producing the plates.

Abstract: Continuous distillation process by means of a rectification column for producing stabilised unsaturated carboxylic acids, for example hydroquinone-stabilised acrylic acid, in which a) crude acrylic acid, consisting of acrylic acid and high-boiling by-products, is fed to the rectification column, b) acrylic acid is drawn off as the top product, c) a mixture of high-boiling by-products/acrylic acid is drawn off as the bottom product, d) a stabiliser, for example hydroquinone, is added to the distillate and to the reflux, and e) a temperature-resistant, highly active inhibitor is added to the rectification column a few plates below the reflux supply.

Abstract: A reactor column incorporates one or more discs where fluid product collects upon the upper surfaces The discs incorporate a small cup on their rim, which is joined to a drain tube. USE/ADVANTAGE - The cup arranges the collection and draining of small quantities of fluids which are thermally unstable and tend to polymerise.
