  • Patent number: 10618873
    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.

  • Patent number: 8927737
    Abstract: The present process purifies a salt Cat+X?, where Cat+ is any cation and X? is an organic anion having at least 6 carbon atoms. The salt is an impurity in a composition comprising a water-soluble salt (Cat+)nYn?, where Yn? is an inorganic anion or an organic anion, different from X?, with at most 10 carbon atoms. The process involves converting X? into an acid HX by adding an acid (H+)mZm?, forming two phases: an organic phase comprising HX and an aqueous phase comprising the water-soluble salts (Cat+)mZm? and (Cat+)nYn? or acids (H+)nYn?. The organic phase is separated and the aqueous phase passes over a basic anion exchanger which binds Zm? and Yn? and liberates OH?, giving an aqueous mixture comprising Cat+OH?. The organic phase and the aqueous mixture are converted into Cat+X? and H2O, optionally with addition of further HX.
