Ethylene Glycol → HCID 22281024, compound

Participants

Reaction Steps

40.0 g of (5-norbornen-2-yl)acetoaldehyde, 23.0 g of ethylene glycol, 120 ml of toluene and 200 mg of p-toluenesulfonic acid were mixed and heated under reflux for one hour while the water formed was removed through an H tube. The reaction mixture was allowed to cool down and poured into 50 ml of saturated sodium bicarbonate water. The resulting mixture separated into two layers. The organic layer was washed with water and saturated sodium chloride water, dried over anhydrous sodium sulfate, and concentrated in vacuum. It was further purified by vacuum distillation, obtaining 50.3 g of 2-(5-norbornen-2-yl)methyl-1,3-dioxolane (boiling point 63° C./200 Pa, yield 95%).
