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： The hydrolytic saccharification method and hydrolytic saccharification apparatus according to the present invention use a hydraulic cylinder-type pressurized reactor as a reactor for causing cellulosic biomass to be in a supercritical or subcritical state, and use a hydraulic cylinder-type steam compressor as a source of superheated steam, such that the reactor and the compressor are operated in conjunction with each other. Surplus hydraulic pressure that is generated when hydrolysis of the cellulosic biomass is completed is recovered as compression power of the hydraulic cylinder-type steam compressor. Moreover, flash steam generated from slurry containing a hydrolysate is supplied to the hydraulic cylinder-type steam compressor for cyclic use of the flash steam.
