反应步骤

In a 250 ml flask were added 30 g (0.18 mole) of 1-(2,6,6-trimethyl-3-cyclohexen-1-yl)-2-ethanone (94% purity), 12.0 g of butyl acetate, an aliquot according to Table 1 of the catalytic solution as prepared above and a quantity of co-ingredient according to Table 1. The resulting mixture was stirred at 100° C. To said mixture, 4.0 g (0.09 mole) of acetaldehyde, diluted in 10 g of butyl acetate were introduced under the surface of the liquid, over 3 hours. After the completion of the introduction the reaction was cooled to 35° C. To the cooled reaction medium were added 10 g of acetic acid and then 40 ml of water. After stirring a few minutes, the water phase was removed and the organic phase was neutralized by washing it with 25 g of 20% aqueous potassium carbonate.
