Embodiment Construction
[0014] 1, Preparation of 3-vinyl citronellal
[0015] Put 15.4g (0.1mol) of geraniol and 9.5g (0.03mol) of mercuric acetate in a 250ml round bottom flask, then add 72g (1mol) of newly distilled vinyl ether, blow nitrogen, then cool to 0°C and react for 24 hours . followed by 10% Na 2 CO 3 After the aqueous solution was reacted for 0.5 hours, the organic phase was extracted with ether, dried over anhydrous sodium sulfate, and the solvent was evaporated. The residue was heated to 180°C in an oil bath and kept for 0.5 hours. The product was chromatographed on a silica gel column (petroleum ether / chloroform=1 / 2) to obtain 9.38 g of aldehyde, with a yield of 52.1%.
