Abstract: 2-Imidazolines are prepared by reacting N,N'-diformyl-1,2-diamines in the gas phase at 200 DEG -350 DEG C., in the presence of certain amounts of an inert gas, over zinc oxide of a particular structure or over a mixture of this zinc oxide and aluminum oxide, as the catalyst. The 2-imidazolines obtainable by the process according to the invention are valuable starting materials for the preparation of dyes, crop protection agents and drugs.
