Abstract: Organic condensation reactions are carried out at elevated temperatures by a method in which the starting material or materials are fed in, in gaseous form, at the bottom of a reactor charged with a mineral oil having a boiling point of not less than 150 DEG C., or are fed in, in liquid form, at the bottom of the reactor, and the mineral oil is kept at a temperature which is no lower than the boiling points, of the starting materials introduced as liquids, which correspond to the partial pressures, of the said starting materials, resulting at the bottom of the reactor, and the product is taken off, in gaseous form, at the top of the reactor.

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: Regeneration of Cu catalyst used in hydrating acrylonitrile or methacrylonitrile to their amides takes place by washing the inactivated catalyst with deminineralised and O2-free water, esp. condensn. water, at 20-150 (40-90) degrees C. Catalysts contain Cu and an Mg silicate, prepd. by pptg. an Mg cpd. with an alkali silicate in the presence of a Cu cpd. Wash liq. can be rejected without further purificn. and/or recycled to amide prepn. if it contains significant amide or nitrile quantities. Useful life of the Cu catalysts can be prolonged 2-10 times.
