Versuchsvorschrift
A 1-liter glass flask equipped with a stirrer, thermometer, gas inlet, and distillation outlet was charged with 174.2 g (1.00 mole) of dimethyl adipate, 198.3 g (2.20 moles) of ethylene glycol, and a small amount of tetrabutyl titanate as a catalyst. The mixture in the flask was purged with nitrogen, heated to 190° C., and reacted at this temperature for 1 hour. As the reaction proceeded, bis(2-hydroxyethyl)adipate was produced with the distillation of methanol from the flask.
