Reaktionsschritte

The 4-allyloxymethyl-2,2-dimethyl-1,3-dioxolane was prepared by mixing acetone, 225 parts, 3-allyloxy-1,2-propanediol, 195 parts and toluene, 480 parts in a flask fitted with a magnetic stirring bar and a water trap mounted with a reflux condenser. Concentrated sulfuric acid, 4 parts, was added to the flask and the mixture was heated to reflux. The first 170 parts of distillate were removed via the water trap, after which reflux was conducted and water was collected in the water trap. After 13 hours the reaction mixture was cooled, neutralized with aqueous sodium bicarbonate, distilled to remove water and toluene and then distilled under vacuum to give 161 parts of 4-allyloxymethyl-2,2-dimethyl-1,3-dioxolane having a boiling point of 57° to 58° at 4.5 Torr.
