PHENYLACETOACETONITRILE

Ethyl a-phenylacetoacetate can be prepared by the hydrolysis of a-phenylacetoacetonitrile in absolute alcohol with dry hydrogen chloride.1 The present method differs in specifying neutralization of the hydrogen chloride with sodium carbonate and hydrolysis of the imino ether in aqueous sulfuric acid, so that the product separates as fast as it forms, thus being protected from further decomposition, with a considerably increased yield as the result. [Pg.39]

If pure dry a-phenylacetoacetonitrile is used, half its weight of water.should be added to the sulfuric acid, or charring will take place on the steam bath. [Pg.55]

In a 250-ml. three-necked flask equipped with a stirrer and a condenser are placed 75 ml. of 60% sulfuric acid and 25 g. (0.093 mole) of a-(4-chlorophenyl)-7-phenylacetoacetonitrile.2 While... [Pg.17]
