Procedure

A reaction vessel equipped with a stirrer, a condenser and a decanter was charged with 743.1 g (5 mol) of diethyl oxalate, 56.9 g (0.42 mol) of trimethylolpropane and 0.55 g (0.8 mmol) of dibutyltin dilaurate, and mixed at 130° C. for 5 hours. After removing 58.6 g of ethanol, it was then cooled and excess amount of diethyl oxalate was evaporated to obtain 158.7 g of crude triethoxalyltrimethylolpropane (yield 87%).
