Versuchsvorschrift

A mixture of 640 g (21.5 mols) of ethanol, 264 g (3.0 mols) of glycol carbonate and 0.1 g of thallium hydroxide is kept at 150° for 2 hours and worked up as in Example 1. A conversion of glycol carbonate to diethyl carbonate of 58% is obtained. The distillation residue is 0.11 g, which corresponds to the amount of catalyst employed; diglycol and triglycol cannot be detected in the distillate.
