摘要

Process and apparatus for the preparation by distillation of mixtures of cleavage products produced in the cleavage of alkyl hydroperoxides arilas ". The present invention claims a process and a device for the preparation by distillation of mixtures of cleavage products produced in the cleavage of alkyl hydroperoxides arilas.Usually, in preparation for the distillation of mixtures of cleavage products that are produced in the cleavage of alkyl hydroperoxides arilas, the mixture of the cleavage products is divided into three major fractions, for which at least two distillation columns are used.The use of two distillation columns has the disadvantage that the capital costs and energy costs, in these conventional processes are relatively high.By the process of this invention for the preparation by distillation of mixtures of products of cleavage, the requirements of equipment and energy consumption can be markedly reduced in comparison with the normal plants, because the product mix of cleavage can be solved in t. Three major fractions in only one device.The process of this invention can be used for the production by distillation of mixtures of cleavage products produced in the cleavage of alkyl hydroperoxides arilas, particularly in the cleavage of cumene hydroperoxide. Using the process of this invention, it is possible to separate phenol and acetone from a mixture of cleavage products that was obtained in the cleavage of cumene hydroperoxide.
