Reaction Conditions

Reaction Steps

Glycidol and acrylic acid which comprises 6.4% by weight of triethylamine hydrochloride and 0.6% by weight of hydroquinone were metered together into a loop reactor heated to 125° C. The metering rate for glycidol was 40 g/h; that for the acrylic acid/hydroquinone/catalyst solution was 41 g/h. The residence time was approx. 15 min. The effluent of the loop reactor within one hour was collected, cooled and admixed with 69 g of trimethyl orthoacetate. The mixture was stirred at 25° C. for 1 hour. A crude product of the 4-acryloyloxymethyl-2-methoxy-2-methyl-1,3-dioxolane was obtained in a yield of 63% by GC analysis.
