Diethyl(phenylacetyl)malonate 化學(xué)特性,用途語(yǔ),生産方法
物理的性質(zhì)
Diethyl(phenylacetyl)malonate has a boiling point of 120 °C. Its density is predicted to be 1.148±0.06 g/cm3.
使用
Organic synthesis intermediates.
製造方法
The anhydrous ethanol co-vaporized with diethyl phthalate and sodium metal is added dropwise to the mixture of diethyl malonate, carbon tetrachloride and magnesium, heated to start the reaction, and the temperature is controlled to smooth the reaction. Then add anhydrous diethyl ether, heat for 1h, add the diethyl ether solution of phenylacetyl chloride (add slowly, not to make the reaction too intense). After the reaction is completed, cool and add water, separate the oil layer, and evaporate the diethyl ether under reduced pressure to obtain diethyl(phenylacetyl)malonate.
貯蔵
Dry and cool place and keep away from strong light.
