반응 단계
A solution of 106.12 g (1.0 mol) of benzaldehyde, 74.48 g (1.2 mol) of ethylene glycol, 500 ml of toluene and a catalytic amount of p-toluenesulfonic acid was heated at reflux in a flask equipped with a Dean-Stark trap for 1 hour and 25 minutes. The solution was cooled, treated with K2CO3, filtered, and distilled to yield 122.9 g of product; bp=163°-5° C./mm.
