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: In parent patent, the continuous prodn. of N-alkylarylamines (I) comprises gas-phase reaction of arylamines (II) with alcohols (III) and/or dialkyl ethers (IV) at 180-450 degrees C in presence of carriers contg. oxyacids of P. The catalyst used is silica of internal surface 50-500 m2/g and H3PO4 content 0.1-20 wt.% and during the reaction H3PO4 and/or alkyl phosphates are continuously supplied to the catalyst. In this addition (II) and (III) or (IV) are introduced as gases at a temp. equal to or greater than the reaction temp. By using the reactants to heat the catalyst, surface coking is reduced.

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: 2-Imidazolines of formula (I) (where R1, R2 and R3 are aliphatic, cycloaliphatic, araliphatic, or aromatic residues, R2 and R3 can also be H, and R1 can also be a gp. of formula (Ia) (in which R4 is an aliphatic residue), e.g. 2-methyl-2-imidazoline or 1,4-di(2-imidazolin-2-yl-)-butane, are prepd. by reacting 1,2-diamines of formula H2N-CH2-CHR3-NHR2 (II) with nitriles of formula R5-CN (III) (where R5 is R1 or a gp. -R4-CN) in the presence of polysulphides of formula Z2-Sx (IV) (where Z is an ammonium gp. or an alkali atom and x is 2,3,4 or 5). (I) are useful as starting materials for dyestuffs, plant protection agents and pharmaceuticals. They are also useful as catalysts for polymn. reactions and polycondensations. They may be converted into the corresp. imidazoles by dehydrogenation on aluminium/zinc oxide catalysts. In comparison with known procedures, the new process is simpler and more economical, and gives (I) in improved yields and purity. Reaction temps. are lower than when no catalyst is used.

Abstract: Prepn. of novolaks comprises reaction of an alkyl phenol with acetaldehyde in a mol. ratio of 1:0.3 to 1:1.5 in the presence of an acid catalyst. The alkyl phenol, in the absence of solvent, is mixed with catalyst and acetaldehyde is added continuously or intermittently so that the pressure is not >5 bar, until the desired mol. ratio is reached. The liq. reaction prod. are removed by heat and/or reduced pressure. The customary use of azeotropic distillation for water removal is omitted and no solvent recovery is involved. The procedure is simplified, yield is higher and effluent problems are diminished.
