Abstract: An improved process of distilling a cyclohexanone-rich overhead stream in a first still from a feed mixture comprising cyclohexanone, phenol and cyclohexanol of the type wherein a cyclohexanone-rich stream is withdrawn as a part of an overheads condensate from the first still and a phenol-rich stream is withdrawn as a part of a reboiled bottom stream from the first still. The improvement includes withdrawing a side stream substantially free of phenol from above the point where the feed mixture is fed to the first column and separating the side stream in a second still into a second cyclohexanone-rich overhead stream and a bottom stream containing cyclohexanone and cyclohexanol. The second cyclohexanone-rich stream may be returned to the first still.

Abstract: Process for the manufacture of acetaldehyde by reaction of ethylene and oxygen in the presence of an aqueous solution of palladium and copper chloride, in which continuously part of the latter solution is regenerated by heating it outside of the reactor. The gaseous mixture leaving the reactor is treated (a) by cooling with recycling of the condensate formed to the reactor and completion of the water portion that has not condensed during cooling, by the addition of water to the reactor, (b) by washing of the cooled gas mixture with water whereby an aqueous acetaldehyde solution is obtained, (c) by extractive distillation of this solution using water as extraction agent. Next, pure acetaldehyde is obtained as an overhead product in a further distillation step. The water demand of step (b) and optionally additionally of steps (a) and/or (c) is satisfied with the waste water obtained in the bottoms of the last distillation step and the residual waste water in each case is discharged.

Abstract: Disclosed is a process for separating 11-cyanoundecanoic acid, cyclohexanone and .epsilon.-caprolactam from a pyrolysis product obtained by pyrolyzing 1,1'-peroxydicyclohexylamine in the presence of steam at a temperature of 300.degree. to 1,000.degree. C. The pyrolysis product is first contacted with a mixture comprised of aqueous ammonia and at least one organic solvent selected from benzene, toluene and xylene, and the so prepared liquid is separated into the oily layer and the aqueous layer. On one hand, the oily layer is distilled to separate cyclohexanone therefrom. On the other hand, the aqueous layer is acidified to a pH of below 4.0 by adding thereto a mineral acid and maintained at a temperature of 40.degree. to 100.degree. C. to separate crude 11-cyanoundecanoic acid in molten form from the aqueous layer, and then, the separated crude molten 11-cyanoundecanoic acid is washed with hot water to extract .epsilon.-caprolactam therefrom.
