Production method:
Diethyl phthalate and sodium metal co-steamed anhydrous ethanol, drop to the mixture of diethyl malonate, carbon tetrachloride and magnesium, heat to start the reaction, control the temperature to make the reaction smooth. Then add anhydrous ether, heat for 1h, and add the ether solution of phenylacetyl chloride (slowly add, do not make the reaction too intense). After the reaction, cool and add water to separate the oil layer, evaporate the ether under reduced pressure to obtain diethyl phenyllevulonate.
