    Abstract: Cyclic lactams are prepared by reacting an aminocarboxylic acid compound of the formula I H2N-(CH2)m-COR1 I where R1 is -OH, -O-C1-C12-alkyl or -NR2R3 and R2 and R3, independently of one another, are each hydrogen, C1-C12-alkyl or C5-C8-cycloalkyl and m is an integer from 3 to 12, with water by a process in which the reaction is carried out in the liquid phase using a heterogeneous catalyst.

    Abstract: A process for producing 2-cyano-3,3-diary acrylic acid esters of general formula (I) in which R and R are hydrogen, C1-C12 alkoxy groups or di-(C1-C4 alkyl) amino groups and R 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 DEG 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.

    Abstract: Caprolactam is prepared by cleaving oligomers or polymers containing essentially the repeating unit -[-N(H)-(CH2)5-C(O)-]- in the presence of a catalyst at elevated temperatures by a process in which the cleavage is carried out in the liquid phase in the presence of a heterogeneous catalyst and of an organic solvent.
