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.

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: 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: (I), prepn. by reaching butenediol esters, (II), with at least equiv. quantities of HCN at 60-160 degrees C., takes place in aq. solns. of CuBr contg. alkali bromide, under pressures >=2 (pref. 2-20) bar. Mol. ratio CuBr to (II) is (0.3-0.6) : 1. The alkali bromide is esp. NaBr. The aq. solns. pref. also contain NH4Br and up to 10 wt.% HBr. (I) can be hydrogenated to hexamethylene diamine, used in polyamide prodn. On replacing previously used CuCl + alkali halide by CuBr + alkali bromide, yields of (I) can be increased, e.g. from 30% to >80%. Process can be effected economically on a large scale. Aq. solns. are handled more easily than fused salts. (I) is easily separated.
