【Abstract】 2-cyclohexylidene cyclohexanone Ⅰ and 2-cyclohexenyl cyclohexanone Ⅱ were prepared by the condensation of cyclohexanone under the catalysis of Fe₂（SO₄）₃·xH₂O in the presence of solvent such as cyclohexane, benzene, and toluene or without solvent in 49～52％（Ⅰ+Ⅱ） yields. The mixture of resultants Ⅰ and Ⅱ was purifield by TLC（cyclohexane:ethylacetate=8:1）to yield Ⅰ and Ⅱ（Ⅰ:Ⅱ=1:4）.Glycol or 1,2-propanediol attaches to the carbonyl group of aldehydes or ketones in the presence of Fe₂（SO₄）₃·xH₂O to yield acetals or ketals Ⅳ_a-k in 44～84％ yields.更多还原
