Abstract: Imidazoles are prepared by reacting 2-imidazolines at from 250 DEG to 500 DEG C. in the presence of molybdenum oxide and nickel oxide and/or cobalt oxide and aluminum oxide, silicon dioxide and/or silicates as catalysts. The imidazoles obtainable by the process according to the invention are valuable starting materials for the preparation of dyes, crop protection agents, textile auxiliaries, catalysts for polyurethanes and epoxy resins, surfactants and drugs, for example the corresponding nitroimidazoles.

Abstract: A novel process for the preparation of 2-imidazolines by reacting 1,2-diamines with nitriles or carbonyl compounds in the gas phase at from 200 DEG to 450 DEG C. in the presence of an oxide or phosphate of a metal of group 3 or 4 of the periodic table and/or in the presence of silicon dioxide. The 2-imidazolines obtainable by the process of the invention are valuable starting materials for the preparation of dyes, crop protection agents and drugs.

Abstract: Prodn. of imidazoles of formula (I) comprises (a) reacting 1,2-diamines of formula (II) with carboxylic acids of formula (III) or (b) dehydrogenating 2-imidazolines of formula (IV), in either case by heating at 300-600 degrees C in the presence of zinc oxide or a mixt. of zinc oxide and aluminium oxide as catalyst: (R1 - R4 = H or an aliphatic, araliphatic, cycloaliphatic or aromatic residue). (I) are intermediates for dyes, plant protection agents, textile aids, polyurethane and epoxy resin catalysts, surfactants and pharmaceuticals (e.g. nitroimidazoles). They can also be used as catalysts for polymerisations and aldol condensations. (I) is obtd. in good yields and purity. The catalysts used are cheap and easily regenerated, and are not significantly poisoned after prolonged use.
