    摘要： There is provided a process for the manufacture of phenolic compounds by separating a neutralized aralkyl hydroperoxide cleavage mass stream containing salts of neutralization into a crude ketone stream and a crude phenolic stream containing the salts of neutralization; separating the crude phenolic stream into a concentrated phenolic-rich stream, enriched in phenolic compounds, and a crude phenolic bottoms stream enriched in tars and alpha methyl styrene dimers, each compared to the crude phenolic stream, said crude phenolic bottoms stream containing salts of neutralization; to the crude phenolic bottoms stream, adding water and a diluent composition, thereby forming a phase separable crude phenolic bottoms stream, said diluent composition comprised of hydrocarbons phase compatible with the crude phenolic bottoms stream and having a combined density lower than the density of the crude phenolic bottoms stream; separating the separable crude phenolic bottoms stream into a hydrocarbon phase and an aqueous phase containing salts of neutralization; whereby the amount of salts of neutralization in the hydrocarbon phase is reduced compared to the amount of salts of neutralization present prior to separation.

    摘要： A process is described for the recovery of phenol and biphenols from their homogeneous mixtures containing benzene, sulfolane and water, which is based on the use of an alkaline solution and benzene for the separation of biphenols from sulfolane, after removing the benzene, H2O and phenol contained in the reaction effluent. The process allows the recovery of phenol and biphenol by-products dissolved in sulfolane, directly obtaining the purified solvent containing the benzene necessary for the feeding to the reactor for the direct oxidation of benzene, as well as the biphenols dissolved in water and pure phenol.

    摘要： The present invention relates to a process for preparing phenols, in which the pH of the reaction product from the acid-catalyzed cleavage of alkylaryl hydroperoxides is set to a value of at least 8 at a temperature of at least 100° C. prior to the work-up of the product. This measure enables the content of undesirable by-products, e.g. hydroxyacetone, in the cleavage product to be significantly reduced. This procedure is particularly advantageously integrated into a process for preparing phenols by: a) acid-catalyzed cleavage of alkylaryl hydroperoxides and b) thermal after-treatment of the cleavage product from step a), with the temperature in step b) being higher than in step a) and is at least 100° C., wherein the adjustment to a pH of at least 8 is carried out after the thermal after-treatment and prior to cooling of the cleavage product.

    摘要： A process for the manufacture of a hydroxy-substituted organic compound comprising decomposing an organic hydroperoxide, preferably a compound of the formula ArnullC(CH3)2O2H, wherein Ar is a substituted or unsubstituted mononuclear or polynuclear aromatic group. The decomposition is carried out in the presence of a catalyst comprising highly fluorinated polymer having sulfonic acid groups with the catalyst being in the form of particles of which at least about 20 weight % have a particle size less than about 300 nullm. Cumene hydroperoxide can be decomposed in the process to phenol and acetone which can be reacted to form bisphenol A in the presence of the same catalyst that was used for the decomposition.
