반응 단계
268 g (2 moles) of 2,2-bis-hydroxymethyl propionic acid are refluxed for 10 hours in 800 ml of glacial acetic acid and 416 ml (4.4 moles) of acetic acid anhydride. The reaction solution is freed from the solvent in vacuo. The oily residue is stirred with 1500 ml of petroleum ether, the carboxylic acid ester is crystallizing out. It is filtered off under suction and washed with petroleum ether. Yield 420 g (96% of the theoretical); Mp. 85° C.
