2-[2-(1,3-dioxolan-2-yl)ethoxy]ethanol

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a 500 ml four-neck round bottom flask equipped with a mechanical stirrer, condenser, thermometer and addition funnel were added 22.0 g triethylamine, 32.4g.2-[2-(2-hydroxyethoxy)ethyl-1,3-dioxolane, and 180 ml methylene chloride. The temperature was reduced to about 0° C. to -5° C. A total of 23.22 g. methacryloyl chloride was added dropwise through an addition funnel. While maintaining the temperature at about 0 to -5°, the mixture was then allowed to warm to room temperature and stirred for 30 min. and added to an equal volume (180 ml) of ice-water. The methylene chloride layer was separated from the aqueous layer, a small amount of anhydrous magnesium sulfate (3 g) was added, the solution was filtered, and methylene chloride was stripped off to isolate the product. Purification was done by distillation at 106° C. under 0.2 Hg pressure.

実験手順: The preparation was similar to that used for the preparation of the monomer designated III except that 22.0 g triethylamine, 32.4 g 2-[2(2-hydroxyethoxy)-ethyl]-1,3-dioxolane and 180 ml methylene chloride were added initially and 23.22 g methacryloyl chloride were added dropwise. The monomer was purified by distillation at 106° C. under 0.2 mm Hg pressure. that used for the preparation of the monomer were added initially The monomer was purified by distillation at 106° C. under 0.2 mm Hg pressure
