Abstract: PURPOSE:To prepare phenazine in high yield, with reduced amount of catalyst, by carrying out the dehydrogenation reaction of 1,2,3,4,6,7,8,9- octahydrophenazine in a specific solvent in the presence of a catalyst comprising the VIII-group noble metal of the periodic table. CONSTITUTION:Phenazine is prepared by the dehydrogenation reaction of 1,2,3,4, 6,7,8,9-octahydrophenazine in one or more organic solvents selected from hydrocarbons and ethers having a boiling point of >=200 deg.C in the presence of a catalyst comprising the VIII-group noble metal of the periodic table, especially preferably Pd or Pt catalyst, under the reflux of the organic solvents, under normal pressure. The organic solvent is especially preferably diethylene glycol or triethylene glycol. The dehydrogenation catalyst is preferably supported on a carrier such as activated charcoal, alumina, etc. USE:Raw material of an azine dye having phenazine ring, raw material of phenazine oxide which is a pesticide effective to bacterial leaf blight of rice plant, etc.

Abstract: PURPOSE:To separate the titled compound in high purity in a simple and ready operation, from a mixture of benzene and/or cyclohexane, containing cyclohexene, with silica gel adsorbing the benzene and cyclohexene selectively as an adsorbent. CONSTITUTION:A mixture of benzene and/or cyclohexane, containing cyclohexene, is brought into contact with silica gel freed of water, etc., adsorbed, in advance of use, by calcining at 100-300 deg.C, etc., as an adsorbent, preferably at -10-80 deg.C, more preferably at 0-50 deg.C, for the selective adsorption of the benzene and/or cyclohexene, to separate and recover high-purity cyclohexene by desorption with a well-known method. The silica gel mentioned above may be a commercially available one in the form of powder or fragments. USE:A raw material for organic synthesis of cyclohexanol, adipic acid, etc.

Abstract: PURPOSE:High-purity cyclohexene used as an intermediate for organic syntheses is isolated inexpensively by simple operations from a mixture containing benzene cyclohexene by the use of Y-type aluminosilicate zeolite from which alumina is previously removed by treatment. CONSTITUTION:Benzene is removed from a mixture of cyclohexene, cyclohexane and benzene by adsorbing it on a Y-type aluminosilicate zeolite of the formula Mn/2O.Al2O3.xSiO2yH2O (M is metal, n is valency of M; x is 3-6 and y is the content of crystal water) which is previously subjected to alumina removing and dewatering treatment at 200-600 deg.C, at a temperature preferably of 0-50 deg.C. Then the mixture of cyclohexane and cyclohexene is treated with another zeolite of the same type to remove cyclohexene by adsorption. Finally benzene and cylcohexene adsorbed on the zeolites are liberated by heating and recovered respectively.

Abstract: PURPOSE:The selective adsorption of cyclohexene in benzene is conducted by using an adsorbent of Y-type aluminosilicate zeolite thereby isolating cyclohexene of high purity in simple operation and high economy. CONSTITUTION:A mixture of cyclohexene along with benzene and cyclohexane is brought into contact with a Y-type aluminosilicate zeolite of the formula Mn/2O Al2O3.xSiO2.yH2O (M is metal, n is valency of the metal, x is 3-6, y is the content of crystal water) which is previously subjected to dewatering treatment at 200-600 deg.C, at 0-50 deg.C to remove benzene by adsorption. Then the resulting mixture of cyclohexene and cyclohexane is treated with another Y- type aluminosilicate zeolite to remove cyclohexene by adsorption. The cyclohexene and benzene adsorbed on zeolites are liberated from zeolites by heating and recovered respectively.

Abstract: PURPOSE:To separate and recover the titled compound selectively and in high yield through a simple and ready operation from a mixture containing cyclohexene and cyclohexane, by using silica gel as an adsorbent and a specific alkylbenzene as a desorbing agent. CONSTITUTION:Benzene is removed from a reaction mixture containing the benzene, cyclohexene and cyclohexane. The resultant mixture is then mixed with a solution of a desorbing agent containing a 7-10C alkylbenzene having 1-3 alkyl substituent groups as a chief component. The liquid phase mixture thus obtained is then mixed with an adsorbent of silica gel from which water is removed in advance at room temperature to 200 deg.C and atmospheric pressure to 30kg/cm to drive out the selectively adsorbed cyclohexene and separate and recover the high- purity cyclohexene. The desorbing agent itself used for expelling the cyclohexene can be circulated continuously for reuse as a desorbing agent by the adsorbing operation of the cyclohexene. USE:A raw material for the organic synthesis of cyclohexanol, adipic acid, etc.

Abstract: PURPOSE:To provide a simple means for the adsorption separation of cyclohexene from a mixture of cyclohexene and cyclohexane, easily, economically, in high purity, using a zeolite-type adsorbent in combination with trimethylbenzene as a desorbent. CONSTITUTION:Cyclohexene is adsorbed and separated from the mixture obtained by separating benzene from a mixture of benzene, cyclohexene and cyclohexane, using an X-type or Y-type aluminosilicate zeolite as an adsorbent and a solution containing trimethylbenzene as a desorbent. The adsorption is carried out by treating the mixture with the adsorbent adsorbed with the desorbent, whereby the desorbent is substituted by cyclohexene. In case of desorption, the adsorbent adsorbed with cyclohexene is brought into contact with the desorbent, by which the adsorbed cyclohexene is desorbed with the desorbent. The desorbent is recycled and reused.
