In a 300-ml three-necked flask, 98 g (1 mole) of cyclohexanone, 148 g (2 moles) of n-butanol, 50 g of molecular sieve 4A, 2 mg of cerium chloride hexahydrate and 40 g of toluene were charged. The resulting mixture was stirred at 25° C. under atmospheric pressure for 12 hours in a nitrogen atmosphere. After the removal of the molecular sieve 4A, the solvent (toluene) and unreacted starting materials were distilled off under reduced pressure. Distillation of the residue under reduced pressure gave 212.2 g of cyclohexanone dibutyl acetal (yield: 93.1%).
