    摘要： To improve energy efficiency of prior art processes while preserving the standards of quality and total yield of desired end products, a process for the preparation of phenolic compounds is proposed. The process of the invention comprises working-up of the cleavage product mixtures by distillation, which comprises resolving the cleavage product mixture into at least three fractions in a single distillation step by feeding the cleavage product mixture to the side of a distillation column, removing a first fraction comprising the ketone at the top of the distillation column, removing a second fraction comprising the phenolic compound at the bottom of the distillation column, and removing a third fraction comprising unreacted the alkylaryl compound and the hydroxy ketone, and water, as side stream, whereby the side stream take-off is situated above the feed of cleavage product mixture to the distillation column, characterized by removing heat from the distillation column, whereby the heat take-off is situated above the side stream take-off of the third fraction, and a process for separating phenol from cleavage product mixtures, wherein the cleavage product mixture prior feeding into the distillation column, is preheated to a temperature of above 70° C. at standard pressure, preferably to a temperature of above 100° C., more preferably to a temperature between 110° C. and 180° C., most preferred to a temperature of about 140° C. to 146° C., and an apparatus suitable therefore.

    摘要： A process for the cleavage of alkylaryl hydroperoxides includes steps for producing a mixture of a concentrate that contains at least one alkylaryl hydroperoxide to be cleaved and a cleavage product obtained from the cleavage of an alkylaryl hydroperoxide, dividing this mixture into at least two parts and cleaving the alkylaryl hydroperoxides in parallel at different temperatures. One of the two parts is treated at a temperature sufficiently high for an integrated thermal post-treatment to be achieved. The process consumes less energy since less steam has to be used. Problems which can result from fouling in heat exchangers are largely prevented. No second feed point for alkylaryl hydroperoxide has to be provided. The process can be used in the preparation of phenol and acetone by the Hock method.
