p-Toluenesulfonic acid → Decane, 1,1-dimethoxy-

Participants

Reaction Steps

Decanal dimethyl acetal was prepared by reacting 796 g decanal with 763.5 g trimethyl orthoformate in the presence of 1.97 g p-toluene sulfonic acid dissolved in 6.07 g methanol at a temperature of 45° C. for a period of time of 0.33 hours. The resulting product was washed with an aqueous 2.5% sodium bicarbonate solution, and then with water; dried over anhydrous sodium sulfate; filtered through CELITE®/sodium sulfate and distilled at 92–98° C. at 4.36–4.97 mm Hg. Then, into a 2 liter reaction flask equipped with stirrer, thermometer, heating mantle, addition funnel, vacuum apparatus, and reflux condenser the following ingredients were added at 17° C.:
