Reaction Steps

47 g of acrylic acid and 3.04 g of p-toluenesulfonic acid were initially charged in a round-bottom flask together with 0.2 g of hydroquinone and heated to 104° C. 40 g of glycidol were added dropwise to this reactant mixture and the resulting solution was stirred at 100° C. for 45 minutes. Subsequently, the reaction mixture was cooled to 25° C. 84 g of trimethyl orthoacetate were added dropwise to this reaction mixture, which was subsequently stirred at 25° C. for one hour. The reaction mixture was then freed of the low boilers present by means of a distillation. Subsequently, a vacuum distillation was carried out at 4 mbar and 95° C. 4-Acryloyloxymethyl-2-methoxy-2-methyl-1,3-dioxolane was obtained in a yield of 56%.
