Abstract: A process for producing aziridines of the formula (I) in which R , R , R , R and R are mutually independently H, C1-C8 alkyl or aryl and R is in addition benzyl, C1-C8 hydroxyalkyl or C1-C8 aminoalkyl, by the intramolecular catalytic dehydration of alkanol amines of the formula (II) in which the constituents R , R , R , R and R have the meanings given in formula (I), in the gas phase at temperatures of at least 250 DEG C on solid catalysts in a fluidised bed at a pressure of 1 to 500 mbar, in which, while maintaining the fluidised bed, a part of the solid catalyst is removed from the reactor, regenerated and fed back into the generator and the aziridines are isolated from the reaction mixture.
