    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: The invention relates to a plant for carrying out chemical reactions, having a reactor (1), the reaction space of which contains hydrogen peroxide (H2O2) and titanium silicalite (TS-1). The object of the invention is to improve such a plant such that continuous separation and recycling of the active catalyst to the reaction space is possible with a long filter service life. This is achieved in that the reaction space contains a solid silicon source, in that the plant comprises a water takeoff line (3) which is set up for drawing off water in addition to components which are dissolved and/or dispersed therein from the reaction space, in that the water takeoff line (3) leads to a filter (4) which separates off the components which are dissolved and/or dispersed in the water, and in that the plant has a return line (5) which is set up for recirculating to the reaction space components which are separated off by means of the filter (4).
