반응 단계
In 1200 milliliters of toluene in a flask equipped with a Dean-Stark tube are dissolved 100 grams of p-bromoacetophenone; and to this solution is added 140 grams of ethylene glycol and 5 grams of p-toluenesulphonic acid. This mixture is refluxed until no further water collects in the Dean-Stark tube. After distilling off 600 milliliters of toluene, the remaining solution is decanted off and evaporated to dryness in vacuo to obtain 2-methyl-2-(p-bromophenyl)-1,3-dioxolane.
