Abstract: The present invention relates to a process for preparing C4-C15 lactams, in which a C1-C10-alkyl nitrite is reacted with a C4-C15-cycloalkane and is illuminated with a light-emitting diode during the reaction. This forms a C4-C15-cyclohexanone oxime which is then converted further to a C4-C15 lactam; the C1-C10 alcohol formed is recycled into the preparation of the C1-C10-alkyl nitrite.

Abstract: The invention relates to a process for the production of 1,6-difunctionalized hexane derivatives from 1,3-diunsaturated hydrocarbons, preferably butadiene, wherein a hydroformylation with carbon monoxide and hydrogen is performed in the presence of an at least dihydric alkanol and during the hydroformylation the temperature is increased. The reaction yields the acetals of the 1,6-hexanedial derivatives which are isolated and further reacted to obtain the desired 1,6-difunctionalized hexane derivatives, in particular 1,6-hexanediamine, 1,6-hexanediol and adipic acid.

Abstract: The present invention relates to a catalytic process for preparing an α,β-ethylenically unsaturated carboxylic acid salt, comprising contacting an alkene and carbon dioxide with a carboxylation catalyst being a transition metal complex, an alkoxide, and an organic solvent, to obtain an α,β-ethylenically unsaturated carboxylic acid salt, the organic solvent being incompletely miscible with water at a pressure of 1 bar at at least one temperature T and selected from amides and ureas, T being a temperature in the range from 10° C. to 90° C.
