Procedure
Into a reactor equipped with a stirrer, a thermometer a gas introducing tube and a dropping funnel, 201 g (1.5 mol) of 2,2-bis(hydroxymethyl)propionic acid, 304 g (3.0 mol) of trimethylamine and 600 ml of chloroform were charged. Under ice cooling, 406 g (4.5 mol) of acryloylchloride were dissolved in 400 ml of chloroform, and the resulting solution was added dropwise to the reaction liquid from the dropping funnel while the temperature of the reaction liquid was kept below 5° C. After the completion of dropping, the reaction liquid was kept under ice cooling and stirred for two hours. Chloroform was then removed from the reaction liquid under reduced pressure. Resulting yellow crystals were purified by column chromatography using as a developing solvent ethyl acetate/n-hexane mixed solvent (1:4 by volume). The solvent was then removed under reduced pressure to obtain 2,2-bis(acryloyloxymethyl)propionic acid as white crystals. ##STR17##
