Patent number: 6657087Abstract: The present invention claims a process and an apparatus for the work-up by distillation of cleavage product mixtures produced in the cleavage of alkylaryl hydroperoxides. Usually, in the work-up by distillation of cleavage product mixtures which are produced in the cleavage of alkylaryl hydroperoxides, the cleavage product mixture is divided into three main fractions, for which at least two distillation columns are used. The use of two distillation columns has the disadvantage that the capital costs, and also the energy costs, in these conventional processes are relatively high. By means of the inventive process for the work-up by distillation of cleavage product mixtures, the equipment requirements and the energy consumption can be markedly reduced in comparison with customary plants, since the cleavage product mixture can be resolved into the three main fractions in only one apparatus.Type: GrantFiled: November 13, 2001Date of Patent: December 2, 2003Assignee: INEOS Phenol GmbH & Co. KGInventors: Markus Weber, Christoph Schwarz, Uwe Tanger, Hermann-Josef Korte, Jochen Ullrich
