    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:High-purity cyclohexene is isolated inexpensively by simple operations from benzene containing cyclohexene by selective adsorption on an adsorbent of X-type alminosilicate zeolite. CONSTITUTION:A mixture containing cycloexene, cyclohexane and benzene is brought into contact with an X-type aluminosilicate zeolite of the formula Mn/2O Al2O3.xSiO2yH2O (M is metal, n is valency of M, x is 2-3, y is the content of crystal water) which is previously dewatered by heating at 200-600 deg.C, at 0-50 deg.C to remove bezene by adsorption. Then the mixture of cyclohexane and cyclohexene is treated with another X-type aluminosilicate zeolite to remove cyclohexene by adsorption. The benzene and cyclohexene adsorbed on above zeolites are liberated by heating and recovered respectively.
