반응 단계
In a 300-ml three-necked flask, 72 g (1 mole) of n-butanal, 144 g of crotyl alcohol, 3 mg of titanium acetylacetonate, 80 g of molecular sieve 4A and 50 g of toluene were charged. The resulting mixture was stirred at 20° C. under atmospheric pressure for 12 hours in a nitrogen atmosphere. After the removal of the molecular sieve 4A from the reaction mixture, the solvent (toluene) and the unreacted starting materials were distilled off under reduced pressure. Distillation of the residue under reduced pressure gave 189.1 g of n-butanal dicrotyl acetal (boiling point: 116° C./25 mmHg) (yield: 95.5%).
