Abstract: Cyclohexane derivatives such as cyclohexanol and cyclohexyl carboxylates are produced directly from aromatic hydrocarbons. The reaction may be carried out, under hydrogenation conditions, by reacting an aromatic hydrocarbon with hydrogen and a reagent selected from the group consisting of water, and carboxylic acids in the presence of a strong acid and a hydrogenation catalyst.

Abstract: Cyclohexanol is dehydrated to cyclohexene by heating it in the presence of a heteropolyacid catalyst. The heteropolyacid is selected from tungstophosphoric acid, tungstosilicic acid, molybdophosphoric acid and molybdosilicic acid. Tungstophosphoric acid can be improved in its catalytic performance by calcination. The dehydration reaction is preferably carried out in liquid phase continuously removing cyclohexene by distillation.

Abstract: PURPOSE:To prepare a cyclohexanol derivative useful as a solvent and a raw material of polymer, in one step, by the reductive addition reaction of an aromatic hydrocarbon with hydrogen in the presence of a mixture containing a strong acid, water, and if necessary, an organic acid, using a noble metal of VIII group of the periodic table as a catalyst. CONSTITUTION:The preparation of cyclohexanol derivative of formula (Ac is H, organic acid residue or strong acid residue; R is alkyl; n is 0, 1 or 2) by the hydrogenation of an aromatic hydrocarbon (e.g. benzene) using a noble metal of the VIII group of the periodic table (pref. Ru or Rh) as a catalyst, is carried out in the presence of a strong acid, and water and/or an organic acid. The presence of the strong acid is essential, and its amount is >=2% of the sum of the strong acid and water and/or an organic acid. The strong acid is, e.g. sulfuric acid, phosphoric acid, etc., and the organic acid is, preferably acetic acid.

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.
