Synthesis of Diethyl Ethylmalonate

The synthesis involves the following steps: dissolving 2.3g of sodium in 25g of anhydrous alcohol, with the resulting sodium ethoxide solution gradually treated with 16g of cooled ethyl diethylmalonate. The transparent crystals of sodium ethoxide are initially separated, followed by the formation of a substantial amount of sodium malonate paste. Portions of 20g of ethyl iodide (or equimolar amounts of ethyl bromide) are added dropwise to the substance via oscillation. The reaction mixture is then heated until the liquid no longer exhibits alkaline reactions, which may take one to two hours. The alcohol is evaporated, the residue is treated with water, and the reaction product is extracted with ether. After evaporating the ether, the residue is distilled to collect fractions at 206-208°C. The yield of diethyl ethylmalonate is approximately 15g. The synthesis route is as follows:
