Diethyl(phenylacetyl)malonate production method: the diethyl phthalate and sodium metal co-steam absolute ethanol, drop into the mixture of diethyl malonate, carbon tetrachloride and magnesium, heating to start the reaction, control Chemicalbook temperature to make the reaction gentle. Then add anhydrous diethyl ether, heat for 1h, and add the diethyl ether solution of benzyl chloride (add slowly, not to make the reaction too intense). After the reaction, the oil layer was separated by cooling and adding water, and the diethyl phenyllemalonate was obtained by steaming diethyl ether under reduced pressure.
