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: A refrigeration apparatus (1) is provided with a refrigerant circuit (1E) along which are connected a compressor (2), an outdoor heat exchanger (4), an expansion mechanism, an indoor heat exchanger (41) for providing room air conditioning, and a cooling heat exchanger (45, 51) for providing storage compartment cooling. The refrigerant circuit (1E) includes a discharge side three way switch valve (101) for varying the flow rate of a portion of the refrigerant which is discharged out of the compressor (2) and then distributed to the indoor heat exchanger (41) and the outdoor heat exchanger (4) during a heat recovery operation mode in which the indoor heat exchanger (41) and the outdoor heat exchanger (4) operate as condensers. As a result of such arrangement, even when the amount of heat obtained in the cooling heat exchanger (45, 51) exceeds the amount of heat required in the indoor heat exchanger (41), surplus heat is discharged without excessive decrease in the discharge pressure of the compressor (2).
