Customs Code 2918300090

Preparation of Diethyl phenyllevulmalonate Anhydrous ethanol, which is co-steamed with diethyl phthalate and sodium metal, is added to the mixture of diethyl malonate, carbon tetrachloride and magnesium. The reaction is heated to start, and the temperature is controlled to smooth the reaction. Then add anhydrous ether, heat for 1h, add acetyl chloride ether solution (add slowly, do not make the reaction too intense). After the reaction, the oil layer was separated by cooling and water, and the ether was evaporated under pressure to obtain diethyl phenacetomalonate.
