反応手順
In a 300-ml three-necked flask, 98 g of cyclohexanone, 148 g of n-butanol, 50 g of anhydrous magnesium sulfate, 2 mg of bismuth chloride and 80 g of toluene were charged. The resulting mixture was stirred at 10° C. under atmospheric pressure for 10 hours in a nitrogen atmosphere. After magnesium sulfate was removed from the reaction mixture, the solvent (toluene) and unreacted starting materials were distilled off under reduced pressure. Distillation of the residue under reduced pressure gave 207.7 g of cyclohexanone dibutyl acetal (yield: 89.4%).
