Abstract: La presente invención está dirigida a un proceso para preparar aminas. En particular está dirigida a un proceso realizable a escala industrial, en la que una cetoxima puede convertirse en una amida cíclica o acíclica por medio de una reacomodación Beckmann utilizando 2, 4, 6-tricloro-1,3,5-tiazina como catalizador en un solvente orgánico no polar.

Abstract: Processing of a reaction mixture formed by ammoxidation of a ketone with hydrogen peroxide and ammonia using a titanium-containing catalyst in homogeneous solution comprises separation of the catalyst, separation of the product, discarding the water of reaction and recycling of the solvent. The ketone-oxime product is separated by a liquid-liquid extraction in a ternary solvent system.

Abstract: Production of oximes by ammoxidation of a C6-20 carbonyl compound in the presence of a water-miscible organic solvent and a heterogeneous titanium catalyst, separating the catalyst, crystallizing the oxime from the reaction mixture, entraining water from the mother liquor and recycling the solvent. Production of oximes by reacting a carbonyl compound having 6-20 carbon atoms with ammonia and hydrogen peroxide in the presence of a water-miscible organic solvent and a heterogeneous titanium catalyst, separating the catalyst, crystallizing the oxime from the reaction mixture, entraining water from the mother liquor and recycling the solvent comprises using a solvent that boils above 100 degrees C and/or forms an azeotrope with water, distilling water or azeotrope from the mother liquor and recycling the distillation bottoms and optionally the organic phase of the azeotrope.

Abstract: In separators used in thermal technology the components are isolated by means of a mass transfer via a fluidic phase interface. Said interfaces are e.g. vapour-liquid interfaces during distillation, gas-liquid interfaces during absorption and liquid-liquid interfaces during extraction. The interfaces are usually produced by the dispersion of a fluidic phase using a supply of energy provided by means of mixers, pumps, fans or distributors. Packs such as bases, dumped packing or structured packing are used to obtain or renew the interfaces. Phase separation processes of this type can be optimised e.g. by improving the apparatus that is used. The invention therefore relates to packs for multi-phase separators, which have an artificial surface structure consisting of elevations and indentations, whereby the surface of said packs is poorly wettable. The advantage of the inventive packs is that deposits take substantially longer to form on them than on conventional packs. For packs that are used in particular in extraction apparatus, such as e.g. packing, or auxiliary coalescence agents in the form of plates, the poor wettability of the surface of the inventive packs aids the thorough mixing and subsequent isolation of the phases.

Abstract: The invention relates to a process for working up a reaction mixture which is formed by ammoximation of a ketone by means of hydrogen peroxide and ammonia in homogeneous solution over a titanium-containing catalyst. The process comprises separating off the oxime product, discharging water of reaction and recirculating the solvent, wherein the oxime formed is separated off in the liquid phase using at least one liquid-liquid extraction in a ternary solvent system.
