摘要: Impurities, that is, by-products, in an oxidation product solution obtained by oxidation of diisopropylbenzene by molecular oxygen or in the oxidation product solution freed from diisopropylbenzene dihydroperoxide, are removed by extracting the by-products such as carbinols, ketones and styrenes from the solution with a mixture of an aqueous alkaline solution and at least one of alcohols having 1 to 3 carbon atoms such as methanol, ethanol, and isopropanol, as an extracting reagent at a temperature of 20.degree. to 80.degree.C.

摘要: Resorcinol and hydroquinone are recovered in mixture at a high purity from a solution containing resorcinol and hydroquinone, especially, a solution resulting from cleavage of oxidation products of isopropylbenzene and successive distillation of the cleavage product thereby to remove lower and higher boiling components therefrom, by adding 0.5 to 20 parts by weight of at least one solvent selected from aromatic hydrocarbons, aromatic hydrocarbons having lower alkyl substituent groups, and aliphatic hydrocarbons having 7 to 10 carbon atoms to one part by weight of said solution, if necessary, together with 1 to 30% by weight of at least one compound selected from ketones having 3 to 10 carbon atoms, alcohols having 1 to 5 carbon atoms and aliphatic esters having 3 to 5 carbon atoms, based on the weight of the organic solvent, dissolving the solution into the organic solvent by heating, separating a mixture of resorcinol and hydroquinone as a solid phase from the organic solvent layer after slow cooling, and recovering the solid phase as a product. The resorcinol and hydroquinone in the organic solvent layer are further recovered through extraction with water. When water is used together with the organic solvent from the beginning of extraction, the resorcinol and hydrocarbon are obtained in an aqueous layer.

摘要: In a process for the production of hydroperoxides by the oxidation of an aromatic hydrocarbon having at least one tertiary carbon atom with oxygen or an oxygen containing gas in the presence of an aqueous alkaline solution, an improvement is made in that the oxidation is effected in an emulsion phase which is caused by powerfully mixing all or a part of the materials to be brought into the oxidation reaction only by the aid of the hydroperoxides formed in the reaction, whereby enhancing the reaction rate with safety.
