    Abstract: A process for producing 2-cyano-3,3-diary acrylic acid esters of general formula (I) in which R1 and R2 are hydrogen, C1-C12 alkoxy groups or di-(C1-C4 alkyl) amino groups and R3 is a C4-C18 alkyl group which may be interrupted by oxygen atoms in the ether function, by the reaction of benzophenonimine of general formula (II) with a cyanic acid ester of general formula (III), in which the reaction is conducted at 20 to 60 ~C and the ammonia released is continuously removed from the reaction mixture with the aid of a stream of gas or by reducing the pressure to 900 to 100mbar.
