 äthylmalonester siedet bei 1940 unter einem Druck von 12 mm. 



   In ähnlicher Weise lässt sich durch Äthylieren des Phenylzyanessigesters der Phenyl- äthylzyanessigester erhalten. Diese Substanz siedet bei 155  und 18 mm Druck und unterscheidet sich vom   Ausglmgsmaterial   charakteristisch durch ihre Unlöslichkeit in wässrigen Alkalien. 



   Statt des Phenylmalonesters und-zyanessigesters können auch andere   Arylmulon-   ester und -zyanessigester Verwendung finden und statt des angewandten Bromäthy ! s können andere Äthylierungsmittel, wie z. B. Diäthylsulfat usw., benutzt werden.

 EMI2.1
 Ethyl malonic ester boils at 1940 under a pressure of 12 mm.



   In a similar way, the phenylcyaneacetic ester can be obtained by ethylating the phenylcyaneacetic ester. This substance boils at 155 and 18 mm pressure and differs from the base material characteristically in its insolubility in aqueous alkalis.



   Instead of the phenyl malonic ester and cyano acetic ester, other aryl mulonic esters and cyan acetic esters can also be used and instead of the bromoethy used! s can other ethylating agents such. B. diethyl sulfate, etc., can be used.
